What Is Tiny Whoop ?

Introduction:

Little things are awesome! The Tiny whoop drone is small, can run for over 10 minutes and is so much fun to fly. What I like most about it is that it can bump into things without crashing. It just bounces off like a ball. Because of its size and light weight, you can fly it around your house and be rest assured that you won’t destroy anything or cause harm to anyone.

Invented by a group of racers called Team Big Whoop, the tiny whoop drone started out as a blade inductrix and is actually just a modification of it. The Inductrix FPV BNF is a micro quadcopter which comes with a casing and variety of bodies. It is the perfect micro quadcopter for building a tiny whoop drone because it flies really well, because of its blades. The basic additions to the blade Inductrix FPV BNF to achieve a tiny whoop drone are a video transmitter and an FPV camera.

A Tiny whoop drone can be used outdoor and within the home. There are many things you can do with it, but fun and security purposes are the basic applications.

For fun:

  • You can use it to chase your pet around the house or out in the field
  • A simple cruising around the house
  • It is an exciting way to chase people
  • Can be very useful when you want to disturb someone
  • Use it to spy on your friends.

For security:

  • For surveillance around the compound
  • From the comfort of your bed, you can use it to check who is at the door before deciding to answer or not
  • You can use it to search for missing items around the house from a convenient spot.
  • With all these benefits, you surely want at least one of these insane flying machines for yourself.
  • The good news is you don’t need to be an Engineer to build a tiny whoop drone. It is very easy to make thanks to its simple architecture.

Building a Tiny Whoop Drone:

  • These are the items required to build a tiny whoop drone
  • A blade Inductrix FPV BNF (Ready to Fly or Bind and Fly Version)
  • A spectrum transmitter
  • An FX787 FPV camera and video transmitter combo
  • A lot of batteries 1S (150 to 205mAh)
  • Upgrade motors (optional)
tiny

There is an in-built receiver in the blade Inductrix FPV BNF, which supports spectrum transmitter only. I recommend you buy the RTF version as it comes with a TX.The use of upgrade motors in building tiny whoop is optional but I recommend it because they aid in handling the extra weight of the FPV setup with the increased power they supply.



Building Procedure of the Tiny Whoop Drone:

Step one:

Get the blade Inductrix FPV BNF and remove the plastic cover to expose the circuit board. Do not touch the thin red wire, that’s the radio antenna and it can be damaged easily.

Step two:

Get the FX787 FPV camera and video transmitter combo and carefully take off the protective plastic. This will give allowance for the rubber band to keep it securely in place on the Inductrix FPV BNF main board.

Step three:

This should be the only stage that’s going to be a bit challenging. Don’t panic though; we are just going to upgrade the motors.Study the upgrade motors, you’ll notice that the wire color coding is different from that of the stock motors. It is blue and red for clockwise direction but black and white for anticlockwise direction.There is only one way to know the right direction of the quadcopter which is by looking carefully at the inductrix main board to notice an arrow showing you the front direction.

Disconnect the plug, and then use pliers to slowly remove the motor by carefully pushing it upwards without spoiling it.Roll the wire you have left with the motors and be sure to use insulating tape to enclose the motors for them to firmly stay in place. You can easily plug the motor in the proper connector sockets since they’re just next to the main board.

Step four:

The battery source will feed the pads that power up Inductrix FPV BNF and the FPV gear, and you are going to solder the wires to the top end of the circuit board.Measure the power wires to ensure that they can reach the pads.After you confirm the length you can now solder.

Match the red wire from the FPV combo to the pad where a white wire connected under it.The black wire should be matched to the pad where a black wire is soldered from beneath.

Congratulations!You just made your own tiny whoop drone.

SETTING UP TARANIS:

  • Set up a new model
  • Start by turning off the internal RF, and then switch external to PPM, CH-12 AND 30.5
  • Set up channels
  • Auto and Self-level are the only modes on Inductrix FPV BNF and a momentary switch that must be CH-6 will trigger them.
  • For the quadcopter to have proper reaction to sticks, reverse channels 2 and 4.

BINDING:

  • To bind the taranis to tiny whoop, use the OrangeRX module.
  • Quickly press the bind button three times in a row to switch the OrangeRX module to binding mode.
  • Turn off the taranis switch and turn on the quadcopter
  • Press down the bind button on the OrangeRX module and power on the taranis, do this simultaneously.

You should see the LED light on the tiny whoop turning color blue, and also hear beeps indicating that you successfully carried out the binding.



Batteries:

Tiny Whoop drones use 1S 150 to 205mah LiPo batteries, and they are able to fly for one or two minutes.

If you want to enjoy lengthy flight time just get many of them, around twelve to fifteen or so.

Cost:

Building a Tiny Whoop drone will not create a deep hole on your pocket; That’s nothing compared to the immense fun the tiny whoop gives, so go ahead and build one!

How to Build a Quadcopter – Complete Guide

quad_feat

Introduction:

The reason why you are looking at this article is because you have seen epic videos of quadcopter zipping across a field at unbelievable speeds, right?

Today I have created a setup that is focused on a balance point between price, performance and easy for a beginner to build. I do not want to share the cheapest setup like many other tutorials online, simply because they do not tell you how crappy it is once you fly it.

This article is going to be about " how to build a quadcopter " .

quad_feat

The parts I will be compiling, will be from a mixture of places; which will require some time actually to come in. Usually, standard free shipping would take roughly about 30 days depending where you are located.

The two sites I will be getting the parts are from Banggood and Rotorgeeks. The only place I would recommend purchasing batteries is at Hobbyking don’t bother ordering LIPOs from Banggood.com, they are disgusting.

quad_first

Here are the parts you will need to build a quadcopter. I can guarantee that this setup will get the most performance out of your money. The FPV stuff is optional but may as well purchase it in case you choose to fly first person view in the future.

How_to_Build_a_quadcopter_pic3

How To Build A Quadcopter - Quadcopter Parts:

  • Cobra 2203 2400KV (Purchase 4 of these bad boys) (Creates rotation)
  • RotorGeeks RG20 Electronic Speed Controller (Adjust the speed of the motors to allow different characteristics)

First Person View Stuff:

  • Eachine CCD 700tvl 148 Degree Camera Lens w/ 5.8G 200mW FPV Transmitter (Transmit video signals over 5.8ghz frequency)
  • 5.8Ghz FPV Mushroom Omnidirectional Antenna TX/RX Set (CHOOSE TYPE W RP-SMA MALE)

Battery Stuff:

  • Zippy Compact 1300mah 3s 40C lipo (Provides the power supply)

How To Build A Quadcopter - Tools and Misc. you will need:

  1. Soldering Iron
  2. Solder 60/40
  3. Wire cutters and strippers
  4. Heat shrink or electrical tape (preferably heat shrink)
  5. Lots of zip ties short and medium length
  6. Hex Allen screwdriver
  7. Blue thread Loc-Tight
  8. M3 Nylon standoffs
  9. XT60 female battery lead connector
  10. Liquid electrical tape
  11. Extra wire, less than 30 cm
  12. Soldering Flux
soldering_flux

So how do all these parts come together and work? I will explain how it works. The power from the lipo is shared across the power distribution board where the electronic speed controller then powers up the motors. A small voltage converter steps down the main power supply to a steady 5v into the Naze32. The signal wires from the speed controllers are connected to the Naze32 where then the software sends across specific analog values to vary the speed of the motors. The PID’s in the software works with the accelerometer and gyro and doing so will allow the quadcopter to fly with characteristics like self-leveling and headless mode.

To change the direction you are heading; you transmit analog values over the 2.4ghz spectrum with a transmitter where your quadcopter picks it up with its receiver and sends it to the Naze32 to process these values. The video transmitter is then screaming on its frequency and channel to allow the person on the other end to fly fpv. You may have an optional on-screen display to allow telemetry information on the fpv video. The Naze32 outputs values to an OSD where the values are overlayed with the video camera before it gets transmitted over the 5.8ghz spectrum. That sums up how everything will come together, in theory, now let’s get started with the building process!

Now that all the parts have come in, this will be the second hardest part to the “How to Build a Quadcopter” series. I will be teaching you to build everything together while keeping it clean.


How To Build A Quadcopter - The Building Process:

  • Now we need to flash the Naze32 with Cleanflight. To do so, download the Cleanflight Configurator from Google Chrome (Press here). Start up Cleanflight, and go under Firmware flasher, choose the latest firmware for the Naze board. Make sure you have “No Reboot sequence” and “Full-chip erase” checked. There is a small little solder bridge that needs to be done on the Naze32 before plugging it into the computer.There are two pads that say “Boot,” jump it with a blob of solder then connect the board to Cleanflight.This process brings the board into flashing mode. Don’t worry about bricking the board; the Naze32 can not ever be bricked as the bootloader is stored in the chip. Press “Load Firmware Online” and then press flash. Make sure you wait until the program says “successful.” Then finally, you can press connect on the top right.
  • config
  • The next thing I would do first is trim your RC receiver values with the little switches on the transmitter. Center roll, pitch, and yaw to 1500. You can leave the throttle value alone, just make sure it is centered on the transmitter itself. After you have done that, look at throttle value in Cleanflight this will be you “minimum throttle” in the “Configuration” tab. Move the throttle to middle and then maximum all while copying the throttle values to the “Configuration” tab. The next blank you will need to fill out is the minimum command, simply add 20-30 to the “minimum throttle” value and should work perfectly fine.
  • While still in the configuration tab, enable ONESHOT 125, Motor Stop, and enable vBat monitoring. After all the changes have been made, make sure you scroll to the bottom and press save; the board will flash its LEDs and will reboot.
  • Take off propellers and make sure the lipo is not connected during this step. Go under the Motor tab and check the little box and set the motors too full throttle. Then plug in the battery, the motors will start beeping a sequence; wait until its quiet and then pull the master slider down to zero. This will calibrate the speed controllers to be in-sync with the rest of the speed controllers. Wait till it is quiet and unplug the lipo.

How to tune PIDs for a Quadcopter:

If you tried to fly the quadcopter before it is tuned, you might see that quadcopter is jittering like crazy, or it may feel sluggish and unresponsive. The simplest way I can explain what are PIDs: a mathematical algorithm that processes the gyro, accelerometer, and user input values in a way that changes the behavior of the quadcopter. For example, if you want your quadcopter to have a more “locked in” feel, you would want to crank the I-gain so external forces like wind and turbulence would not change its set angle.

Everybody has their preferences and unique setup, so do not bother searching up some random PID values from the internet like many amateurs. Try to learn and understand it, as this will make you a better pilot.

tuning1

How To Build A Quadcopter - The Tuning Process:

  • By this time, you are finished with the PIDs, yay! I would then next adjust the TPA and TPA breakpoint with a simple method. The reason why someone would use TPA is when the quadcopter reaches a high throttle value, the quadcopter would start to shake and vibrate during its way up.This is because the quadcopter is trying hard to correct itself. What the TPA does is decrease the sensitivity of the PIDs when it reaches a certain throttle value. This is where you input the values for TPA breakpoint, so it starts the decrease. Roughly estimate, the whereabouts your finger rest on the throttle when the shaking begins and repeat the same position when you are in Cleanflight to determine the throttle value. Use this value for the TPA Breakpoint.

Do make sure P and I are tuned correctly before this process. Remember that TPA is the opposite of D-gain, where this time you are looking for vibration while it's rapidly ascending instead of rapidly descending.

  • You may find the quadcopter feel unresponsive and even maxing out on the sticks the quadcopter which takes forever to get into that set position. This is when you want to increase the rates. I would suggest adding .3 to roll, pitch and yaw; this should be perfect for starters. Later if you need high sensitive stick movements, like if you want to do a barrel roll while on the spot without losing any altitude, you would need to crank up the rates way to .5 or .6. Do not go up this high unless you know how to fly the aircraft with low rates.

Acro mode, Rate mode & Manual Mode- Debunked

How to Fly Quadcopter in Manual Mode / Acro Mode / Rate Mode:

Flying in manual mode is a mind boggling experience, especially if it is your first time. Most people have already been too comfortable flying in some sort of self-leveling mode like angle mode. Angle mode kicks in the accelerometer with the gyro to self-level the quadcopter if there is no stick input in the pitch, roll, and yaw. The is easier on the pilot since the aircraft can automatically return to the neutral position if they let go of the sticks.Let's start off by looking at what acro mode / manual mode / rate mode mean!

What does Acro mode/Manual Mode or Rate mode mean ?

Simple. Imagine a car with automatic transmission.Imagine a car with manual transmission.The car with manual transmission gives you more control over your speed and what not. In the same way , acro mode /manual mode or rate mode gives you more control over your drone and does so by giving you complete control over the angular velocity of the drone.

Flying in manual mode, acro mode, or rate mode does not return the aircraft in neutral position but instead holds the set position when stick input is not given.

This is useful in situations like doing rolls or flying upside down. Manual mode is something every pilot wants to master for smooth flying . It's the sensation of having limitless control over the aircraft. You put your skills to the test when in manual mode.

how_to_manual_fly

Flying in manual mode is not easy. It will take time and practice. If you are tight on money for this hobby, It is recommended to practise on a drone Simulator like LiftOff or FPV FreeRider.Why? because you will crash a lot, trust me. If you want the realism of the environment, then prepare yourself with bulk loads of propellers and extra motors just in case. Spare arms for your frame will also be handy.

It is recommended to fly manual mode in FPV first as this will make it easier to determine how much your drone is tilting compared to simply flying line of sight. Once your quadcopter and FPV gear is set up you will want to identify the left stick on your transmitter. Some transmitters like the Phantom series has the throttle centered by springs under the stick module. If it is in the center, then you will have to make sure to hold it down to zero, or the quadcopter will start flying upwards thinking it should be at 50% throttle when you arm it. If you have something like a Taranis or Turnigy 9x, you will not have this problem.

acro mode

Now, after all the little details and cautions, here comes the actual tutorial

Hovering:

You want to make sure that you can hover the quadcopter and fight any external forces like wind . Prop wash with the pitch and roll stick before moving around too much. Say, for example, if you feel the quadcopter is drifting to the left because of a small gust of wind, you will want to roll the quadcopter to the right just a tad bit, just so the forces balance out.

You will find yourself constantly making small stick maneuvers as external forces may come and go, this is totally normal. However, if you see the quadcopter slowly tilting by itself when the wind blows, then you will need to crank up some P and I gain into the PIDs. The quadcopter should only be drifting; never leaning .

Another note I like to give is this : If you feel every small stick movement is still a lot, this is where you would want to add some RC expo. Instead of having a linear output, it creates an exponential curve (a slope), so small movements will become even softer.

Flying:

While flying, everything is going to be the same as angle mode except the fact that now when you let go, it remains in the same position. This is unless you manually self-level it. You now have 360 degrees range of motion, meaning the quadcopter can possibly flip over, unlike angle mode which has a set maximum tilt angle.

Say ,if you want to give the aircraft a forward pitch of 10 degrees, then what you want to do is push the pitch a little bit and then let off that stick. If you don't let go and continue to hold it, you will cause it to slowly to continue to pitch forward. Now if you want it to be in a neutral position, then apply the same amount of force in the opposite direction. Sounds simple, right? When you start applying yaw, things get a little more confusing.

Let's go back to the 10 degrees pitch example. If you were to yaw 90 degrees left, the quadcopter will want to stay at that angle but its heading is now changed. Relative to the original position, it is now in a 10 degrees right roll. To compensate that, you will want to roll 10 degrees left instead of pitching 10 degrees backward. Don't get too mathematical about this when flying, focus on small movements and get to feel how the quadcopter behaves when starting out.

Flipping:

I cannot just write a "How to fly in Manual Mode" article without dropping tips on how to flip. Doing flips is very simple, it is all about timing and throttle management. Before trying to perform a flip, you will want to turn up your rates for roll and pitch , or else you be doing massive Ferris wheels in the sky.

Now to perform your first basic side flip : Have the quadcopter about 10 meters off the ground. Punch the throttle for one second to get the momentum going, and then drop the throttle down to 10%, then immediately max out the roll sticks to one direction.

You must carefully observe when the quadcopter is upright again so you can let go of the roll sticks and apply some throttle again. If you noticed your time is off, and don't know how to save it, flip it into angle mode and then apply throttle to prevent it from crashing down.

Take home notes:

The higher the rates you apply, the faster the quadcopter can flip "on the spot" without losing any height. I master the flips before I actually manage to fly decently, it is pretty easy to do once you get the time right. TIMING IS KEY!

*just a note, do not ever throttle down to 0% as the propellors will stop spinning, and that mean you will not be able to flip at all.

In conclusion , flying your drone in acro mode or manual mode is basically just a lot of dedicated practice.

Fatshark Dominator V3 Video Goggles Review

CONVERTER

Why FPV ?

Flying a drone First Person View (FPV) or from the pilot’s perspective is an amazing experience. By strapping a camera to the front of the drone and transmitting this video feed as a live stream to a screen or video goggles, you can control the drone as though you were in it. Although the technology is relatively simple, there is quite a bit of cost involved with switching from line of sight to FPV flying. A large proportion of this cost goes towards the goggles or screen used to view the feed. Today we are looking at the Fatshark Dominator V3 Video Goggles, which are a very good option for those who want a compact lightweight mobile solution.

If you have recently started out flying FPV, it is likely that you went with a system comprising a separate receiver and screen or a set of goggles that utilise a single large screen and a lense to help you focus. These are both great value for money and allow you to get a feel for the hobby without spending too much money. The sacrifice for the low budget is often a system that is bulky or low specification.

The Fatshark Dominator V3 Video Goggles provide a very compact solution, incorporating a built in/swappable receiver, DVR and a screen for each eye. The goggles sit comfortably on your face thanks to the foam padded faceplate, which also blocks out external light, providing a really immersive feel. This is one of the biggest upgrades for users swapping from a screen or the large style goggles, which are heavy and allow light in. Extended flying sessions are now possible with no discomfort. In addition, the padded faceplate has a built in fan to keep the lenses free from any misting. We have found this particularly useful when flying in cooler weather when the goggles would otherwise have fogged up.

Onto the most important thing, video quality! The Fatshark Dominator V3 utilise a 16:9 aspect ratio and an 800x480 resolution. There is a 35-degree field of view and IPD adjustment, so you can line up each screen to each eye perfectly. The image is clear and reasonably crisp even at the corners. The perceived screen size is large, but not huge, we would compare it to having a laptop or tablet at arm’s length. If you are moving from a single screen with lense like we did (Quanum V2) then the screen size may actually be a step down for you, but the screen quality itself is very good and allows you to see even fine details clearly. When using the HDMI port to connect to a computer, the image appears even clearer.

Fatshark Dominator V3 Video Goggles

For us the HDMI port was a very attractive feature, as not only does it allow the goggles to be used with FPV drone simulators for a more realistic and immersive feel, but there are now HD FPV systems available like the Connex Prosight. Having HD ready goggles, with the connectivity required to be able to make the most of the new HD systems was important for us.

The DVR is a feature which we had always missed on the Quanum V2 DIY large screen type goggles. The DVR allows you to record the analogue feed viewed on the goggles and also play back this footage. This is very handy if you ever lose a model and either don’t have a buzzer or the battery disconnects, as you can watch the footage back to see where you crash landed. Being analoge, the goggles can tune into and record your friend's video feed too! A great feature on the Fatshark Dominator V3 DVR is that if you disconnect the battery without stopping the recording, it will still save. This is something that was missing from earlier versions. One thing we would like to see is an auto-pause when there is no signal, as we regularly forget to stop recording between batteries and now have hours of static recorded…

The battery that comes with the goggles is reasonably sized (both physical and capacity) at 1,800 mAh. The battery generally lasts us a whole session of flying, which could be 10-15 packs. It fits nicely into the side of the headband, where it sits comfortably on your head and doesn’t seem to add much to the weight/feel of the goggles when wearing them. If you are planning on dosing a longer flying session it is worth picking up a spare battery; when the battery voltage gets low the goggles make a few beeps before turning off shortly after!

The final piece that makes the whole system work is the changeable receiver module. This is compact and has a cover which seals it into the goggles nicely. The standard module utilises the 5.8Ghz band and supports a single antenna. There are now a number of alternative receivers available, which offer increased functionality such as diversity and favourite channel lists and these slot right into the existing module bay.

PROS:


  • Compact
  • Lightweight
  • Built in DVR
  • Mini HDMI port
  • External video feed in - you can use your old receiver
  • Screen for each eye - can view 3D content

CONS:


  • Price
  • 720p, not full HD
  • Small screen size compared to cheaper options
  • Not much time between low battery warning and video loss

Verdict:

We recently made the switch from the Quanum V2 DIY goggles to the Fatshark Dominator V3 and are very happy with the Dominator V3. The perceived screen size is smaller than the Quanum V2 and there are other options out there that have larger images (such as the Dominator HD2), but we feel that the Dominator V3 provide a good compromise between screen size and blurred edges (experienced when the screen size is too big). The small form factor is fantastic for long flying sessions without getting uncomfortable and the ability to record each and every flight without adding a heavy and expensive camera to the drone is a great feature. We will admit that the price tag is large, but we think it is justified and would definitely recommend the Fatshark Dominator V3 to anyone looking for a set of FPV goggles.

How to use Fatsharks Dominator V3 Goggles with Liftoff or FPV FreeRider

You may all know the famous quadcopter FPV simulators Liftoff and FPV FreeRider which allows you to use your transmitter while being in the virtual quadcopter world. I have seen many people complaining how they want to use these simulators with their Fatshark goggles. Unlike the Headplays HD, where you can simply video out the display through a digital HDMI cable. Fatsharks can only be fed with an analog signal. As you may already know, most computers only have digital display ports.

The trick to convert digital video signal to analog video for your FatShark Goggles :

What you need is a simple module that converts the HDMI signal into the old style yellow composite. eBay sells these “HDMI to composite converter” for surprisingly cheap, only around 15USD. It runs off a 5V USB battery supply which can be connected to the computer while you are using it.

First connect the USB power supply into the little converter. Then unplug the HDMI cable from your monitor into the little converter. If you have a laptop, you will need to plug in an HDMI cable and allow the computer to mirror out through the cable. Once that’s completed, connect the male auxiliary to composite cable provided by Fatshark into the female composite port on the converter. Turn off the video transceiver and you should then only be getting the video from the computer. Voila!Your Fatshark Goggles are now ready!

 

 

How to Waterproof your Quadcopter’s Electronics

Introduction:

I live in an area where if it’s not raining then everything is all muddy and wet. This is a major pain in the ass for me because if I crash, not only does it scoop up a bite of dirt into the motors but covers all my electronics with dew. If you want to learn how to clean the dirt from the motors go here.Recently, I found this product that works absolutely fantastic. It is simply a bottle of Liquid Electrical tape. It covers your electronics with a layer of insulator which works really well when applied the correct way.

Waterproof your Quadcopter’s Electronic

There are many places that sell liquid electrical tape such as:

  1. Home Depot
  2. Walmart
  3. Rona
  4. Canadian Tire
  5. A few electronics store

To apply the liquid electrical tape, what you want to do is use a small brush and dab the fluid onto the components. Do not try to paint the fluid onto the components because this will cause you to miss some metal contacts; due to the varying height of the chips. You can apply it to the flight controller, fpv camera, on screen display, voltage step down and your speed controllers.

Some tips I can give you while using the liquid electronic liquid are:

If there are LEDs on the electronics, apply over it and then later clean it off with a napkin. You do not need to apply a thick layer, or else the drying time will take too long, and possibly not even dry fully underneath. To speed up the drying time, use a small little computer fan which should bring the drying time down to only 3 minutes instead of 8. If you got liquid tape on any connectors, you can carefully scratch off the plastic with a small flat head.

Hubsan X4 Quadcopter Review

Introduction:

Hubsan X4 is a great little quadcopter to start with. It fast and agile .It doesn't burn your wallet. With the price of around 30USD, this quadcopter tops the charts and is one of the most referred-to drones in the RC community. Believe it or not, I can say that I fell in love with the X4, surpassing my love for the QAV250.

Hubsan_x1

In Detail about Hubsan X4:

Having received the Hubsan X4 from Banggood.com for only about 30USD while it was on Black Friday sale, I am more than ecstatic to write about this drone. The package comes with

  1. Hubsan X4
  2. One 380mah 3.7 20C lipo battery
  3. Charging cable
  4. 4 spare propellers
  5. Special propeller removal tool
  6. 2.4ghz Transmitter
  7. Propeller guard (secretly tape underneath the plastic packaging, weird)

The quadcopter has a fantastic hard glossy plastic with four small LEDs to help with the orientation. The frame is specially designed to absorb impacts. This is my favorite thing about the design of the Hubsan X4. The frame is located underneath each arm and when crashed the plastic dislocates from the main arm to absorb the shock (You can then push it back with your fingers), Heck, it doesn’t make a difference in flight performance when even all four motor support gets dislocated. I had many nasty crash and thanks to this, the frame is good as new.

Hubsan_x2

The transmitter, although not fancy like a Turnigy 9x, is pretty comfortable to fit in your hands. Unlike the CX-10, the transmitter is quite small and every small maneuver is quite rapid unless the rate is turned down. The Hubsan X4 surprisingly has adjustable rates for throttle, yaw, roll and pitch separately! You do not usually get this feature on a ‘toy drone’. I, however, do not fly with these features but is quite useful for beginners to turn down the rates for roll and pitch when starting out. Furthermore, the transmitter allows you to change from beginner mode to expert mode. This essentially changes the rates on all channels to high and the quadcopter becomes very sensitive to the stick movements. Other than these two fancy features for the remote, the transmitter also has your basic trims that show on the LCD display. No, the LCD does not light up if you were wondering.

Hubsan_x3

Here is the main reason why I love the Hubsan X4. The customizability! I added a micro 5.8 FPV system on the Hubsan x4 which allows me to fly First-Person View. I will be sharing how I did this in an upcoming tutorial. The Hubsan motors are strong enough to lift extra 6grams of weight with the propeller guards without sacrificing much performance. Not to mention the spare parts and batteries are super cheap. I got 8 extra 380mah 3.7 25C LiPo(s) off eBay which is the same as buying one QAV250 3s battery. I live in Vancouver, where it is mostly rainy weather, and I fly this indoors whenever it’s raining outside. The 5.8 signal can penetrate all three layers of the house.

I highly recommend buying this quadcopter! You will save yourself a lot of time from building, configuring and repairing quads if you choose to purchase the Hubsan X4. Besides it saves you tons of money and very portable to carry around. Plus, as a last note, this is the cheapest way to FPV if you ever wanted to explore into FPV flight.

Let's get started with some FAQ, shall we?

Since most of the readers are from Canada, Australia, Singapore, and India, I am obliged to drop some links as to where to buy the Hubsan x4.

If you are in Australia:

  • Australian Robotics - though the drone is hardly in stock
  • Just Hobbies
  • Try to get this through Amazon.com though you will have to pay additional customs and shipping charges
  • If you want to buy it off eBay , make sure you research your seller properly by looking through his reviews

If you are in India:

  • Amazon.in and Flipkart don't sell popular drones .So, you are left with the only option of buying it through Amazon.com and paying the super hefty 30% customs duty!
  • Even if you do find this on Flipkart and Amazon , it's highly unlikely that it's going to be a fulfilled order by a reputable seller . If you end up buying the Hubsan x4 in India , let us know!

If you are in Singapore:

If you are in Canada:

  • Amazon.ca
  • Pro RC if its out of stock on AMZ

1. Ok, So you bought the Hubsan x4 and the motor goes kaput in a few weeks. What do you do?

Motor replacements for Hubsan x4 is a fairly easy task. But.Never go cheap on a new set of motors.

Check these out and make sure you buy one of these too, just in case. Having replaced a ton of motors, I have never soldered wires together .They are super thin and there is hardly any free space for extra wires in the arms. You can resolder it at the board instead.

2. How do I pimp my Hubsan x4 you ask ?

Batteries :the stock batteries is something you can write home about( for those who don't now Hubsan x4 battery life is about 5 mins and can go about to 9-10 minutes if you plan to upgrade to a 500mah battery kit ) .

ZJchao -(380) though decent, getting a good set of these is like winning the lottery. Poor quality control but a good buy never the less.

Neewer(500) is another option but you may also need to buy their battery charger which pulls about 0.8 amps in total.

The best buy would be the Tenergy though they have a lower 380mah capacity. These, for the most part, do not have any glaring quality control problems and you can be rest assured that each pair won't differ from the other.

Also, all of the above batteries are compatible with all major Hubsan x4 models (Hubsan X4 (H107C-HD), Hubsan X4 (H107C), Hubsan X4 (H107D), Hubsan X4 (H107L)).

Carrying case water proof your drone and can help you carry spare parts which might come in handy.

Protection Guard , if you are into that sort of thing but can be really hard to get a proper fit.

If you need a motor upgrade, check out the dark edition motors MMW

3. Is your Hubsan x4 drifting?

  • Check for hair or lint built up on one or more of the shafts
  • Try to isolate the problem by
    • Turn on the controller and do the stick calibration
    • Power up the Hubsan and bind the thing up with your controller
    • Calibrate the accelerometers by keeping the X4 on a flat surface
  • If you tried all of the above and it still doesn't work - It's probably a motor or electronics issue. Return it!
  • Also, note that some amount of drift is perfectly fine. Make sure you know how bad it is!

Changing BetaFlight PID’s with a MinimOSD

1

This procedure is also applicable to CleanFlight and Betaflight:

Changing your PID’s settings is always important, as different weather and new upgrades will impact the behavior of your quadcopter. Having an OSD can be quite helpful as it saves time from plugging it into a computer. Not only does it give you useful information like voltage, flight time, flight modes and an artificial horizon, it can also change your PIDs settings using your transmitter.

1

*The setup is with a MinimOSD running KVOSD software. KVOSD is an awesome yet simple OSD software dedicated for Cleanflight. If you are not running KVOSD, I would recommend flashing it to KVOSD

2

KVOSD easily allows you to activate its PID’s settings page through a simple maneuver with your transmitter when the quadcopter is on. You have to simply ‘throttle middle and yaw right’ for the left stick and ‘pitch full’ on the right stick for about two seconds. This is for Mode 2, but if you are using Mode 1, remember the sticks are swapped.

Once you are in the PID’s page, you can move the cursor around using pitch and roll. In order to change a setting, simply yaw right to increase and yaw left to decrease the value. Remember to hold for 2 seconds to change one value and hold it for longer more rapidly. To save the settings, move the cursor to bottom ‘Save & Exit’ and yaw right. This will update Cleanflight with the adjusted settings.

BetaFlight Procedures shown as screenshots below:

There are many more settings you can change with the OSD. Move the cursor to 'Page' and yaw right. Here are the options you can change with KVOSD:

Easycap Setup And Review

Introduction:

When I first purchased Easycap from Banggood.com, I was very skeptical. In my mind, I thought about every possible negative thing that can come up when purchasing a cheap fpv setup. This by far has surpassed my expectations!This article will deal about easycap setup and will also offer essential driver links. I am throwing in a small easycap review as well!

Easycap

The Easycap I purchased from Banggood was less than 10USD and comes with not only the analog video connector but also S-Video, left and right audio channels. The quality build feels really nice, comes with durable wires, and a USB cover. The DVR software comes in a small CD and the license code on the face of it. The license code however, did not work for me and I needed to search online for another registration code which then worked. When I first tested out on my 14-inch laptop screen, it was absolutely amazing, the latency was super low! It was so low that, I honestly could fly my QAV250 with the video. Easycap setup is fairly simple too.All you need is a couple of drivers and you good to go!

The DVR software is pretty simple to use. It allowed me to record the DVR footage in decent analog quality however, I felt that the live stream video quality is much better than the saved video. A really neat feature about the Easycap is that, it does not blue screen or shut off, it instead snowflakes the video. I would not even consider it snowflakes since the software replaces the black and white static with colorful pixels. This is less distracting when flying as most of the time the colored static is kind of blended with the rest of the video when the connection is weak.

Now the main question is; would I recommend this for FPV?

I would certainly recommend this for a beginner or someone who wishes to have a cheap DVR. I know that the most popular route currently for beginners is to purchase a TFT monitor as their first fpv setup. Many of these monitors cost in the range $50-$60, whereas if you already have a laptop you can use it. In addition, you get the DVR feature which is a big plus. As for me, you know that I am all about the goggles, for the “cockpit feeling”, but sometimes I like to bring this around if I know I am going to fly with my friends around so they could spectate on a larger screen, instead of viewing it on the 7 inch TFT Color Monitor.

How to Setup up Easycap?

  1. Connect the Easycap to you PC or laptop
  2. Allow the computer to search and install the driver by itself.
  3. Install Honestech TVR from the CD or through Google.
  4. Now open up the software and it will require you to enter the license code. Use the Serial code: TVR25-NMBGG-HGGGH-362DC-6BMG6 you will need to type in each section individually.
  5. Once the software has opened, you may see your webcam if you have a camera connected. You will need to tell the computer to choose the other camera. To do this, press composite on the media bar. You now have live video stream!
  6. To record the video, press the red circle to allow it to record
  7. To stop the recording, press the red circle again
  8. Here is the important part, in order to save the video, you will see a drop down list underneath the media bar, right-click it and press “Save as...”

The video is saved in “.mpg” If you have problems viewing it, use a video converter or the DVR itself to play it back.
