Black Talon FPV Quadcopter

Black Talon FPV Quad is a RC drone for indoor flight, it has a good comprehensive proerty, but its flight time is too short.The drone has gradually become a mainstream digital gadgets, not only take the aerial photography, surveying and other specialized work, even to the competitive direction. For ordinary people, the UAV can also be a great relaxation activities, especially the cheap, easy to use model.

Black Talon FPV Quad is a four-axis compact indoor drone, its price is about $ 139, it iVery suitable for use at home. In addition, it also equipped with a camera, to take pictures and video,Now let’s take a  look at their experiences below.
black-talon-fpv-quad-03
Black Talon FPV Quad has black body, overall is very small, propeller parts has bezel with security, can easily fly in complex family environments. It uses WIFI signals for remote control, frequency is 5.8GHz, it has tested their disturbance is very good, do not conflict with other wireless devices in the home, and the latency is very low.
Black Talon FPV Quad with a wireless controller that handles look like the Xbox One handle, also has a monitor LCD screen to monitor flight. In addition, if you don’t like the RS button on the handle, you can also replace the lever, it is very flexible.
About the battery, Black Talon FPV Quad equipment with a 520mAh lipo battery, it provides about 5-6 minutes flight times, it seemed not very good. Of course, users can buy some other more fast batteries to replace it, I recommend pilots can choose the Tattu fpv batteriesTattu 450mAh 11.1V 75C 3S1P Lipo Battery and Tattu 850mAh 11.1V 45C 3S1P Lipo Battery is very useful to Black Talon FPV Quad, it can last more long, flies more long time .

Black Talon FPV Quad has three sensitivity settings, medium and high settings of the more suitable for outdoor use, after all, need to take into account wind speed cause yaw condition. When used indoors, Black Talon FPV Quad signal penetration is excellent, even flying into the basement in the single-family homes and almost no lag, LCD monitors are also very easy to use.
black-talon-fpv-quad-04
Due to wing has designs of crash, even hit the shelves, cabinets and also not so big problem, airborne and pressure sensor provides excellent flight stability, no one in the small indoor four-axis machine is still relatively rare. Of course, 5-6 minute range is its greatest weakness, maybe you just fly enough, need to replace the battery.
Black Talon FPV Quad is a comprehensive performance, value for money and it is very good in-room , flying and shooting are very satisfied, in addition to poor battery endurance.

Xiaomi Mi Drone 4K Review
In comparison to the 1080p version the Xiaomi Mi Drone 4K uses two sets of independent heterogeneous IMU and compass sensor. Such a combination is met found rarely on UAVs. It helps the drone in providing better flight real-time monitoring by merging data from both sensors.
This drone uses 1.2mm ultra-thin lightweight body design process. It weighs only 670 grams, which can be considered as a record for such kind drones. So unlike many other quadcopters the Mi Drone 4K looks more stylish, but this change doesn’t affect the battery and the lifetime. As you guess, the improvements refer to the battery and lifetime as well. Thanks to 5100mAh battery (actually there are four separate 4.35V high voltage lithium polymer batteries) it can provide up to 26 minutes of continuous flight time.
Xiaomi Mi Drone 4K
The Xiaomi Mi Drone 4K comes with a 12MP Sony back-illuminated sensor, which is capable of recording videos at 3840 x 2160 pixels resolution. Moreover, it saves the files in RAW format. This product is based on new TDMA technology, which means it provides an anti-jamming performance significantly stronger than the traditional Wi-Fi scheme. Moreover, the Xiaomi Mi Drone 4K now supports transmission distance from the original 1km to 4km.
Xiaomi Mi Drone 4K
This camera is packed with a 3-axis brushless self-stabilizing pan, built-in 3-axis gyroscope, 3-axis accelerometer and 3-axis brushless motor driver. So it is capable of providing up to 2000 times better data acquisition and operation compensation.
Every time we talk about this drone we mention there have been made more than 400 software improvements. But this statement doesn’t mean anything to a novice. In other words, Xiaomi has developed a special app allowing to control the Mi Drone UAV easily. You can generate routes, set up automatic takeoffs and landings as well as a destination, flying around a given point and automatic return.
Xiaomi Mi Drone 4K
As for security, when the battery power is too low, the drone returns to the starting point. The same will be implemented if the connection is suddenly lost. Finally, you can track the location of the Xiaomi Mi Drone 4K in real time by GPS.

Build a Fast FPV Racing Quadcopter?

If you want to win a FPV drone racing, there are two important points: one is your superb flight skill, and another is your good FPV drone. About flight skill, you need to do more flight training, but get a good FPV drone is easier than flight skill. So How to build a fast FPV quadcopter?
What’s a good FPV drone? I think a good drone must come with high speed and large acceleration. For racing drones, the acceleration is the most important. As we know FPV drone race track is very short and many track corners. As soon as possible to lift the speed is the most important after the drone pull out the track corner, so it is not a large thrust motor can help you to win a racing, you need a reasonable collocation scheme for your drone.
Build a Fast FPV Quadcopter

In the past, I used QAV 250 frame equip with 1806 motors and 3S Lipo battery can fly very fast; and now I use 2205/2305 motor, come with small and light frame, DALRC6045 propeller, the speed get 185km/h. So how to choose the FPV drone parts?
Motor:
I have used many different motors, and these are some of I used.
  • 2205 motors: equip with dalrc5045 3 propeller, their thrust is about 1200g(motor’s weight is about 30g, 4 motor is 120g)
  • 2206 motors: I have used it, the weight is too heavy, hard to turn the corner, and the speed is not increased significantly;
  • 2305 motors: this is my new test motors, and the thrust is very good, they’re super smooth and have a good power!
Frame:
I have three requirements for select the frame:
  1. Light weight;
  2. Small wind resistance;
  3. Strong and solid;
In the past, I sued dalrc220 frame because it is strong and solid, and needn’t consider the weight, now I like the new frame xr220, because it is light, strong solid and small wind resistance.
ESC:
I think the most ESCs have no difference, the program are similar, you just need consider the price. I’m using the Tattu ESCs, in order to match my Tattu quadcopter motors.
Lipo Battery:
To flight fast, a good lipo battery is very important; low C rate can’t discharge high current, if you want to flight fast, you need at least 60C or more lipo battery. How to choose high discharge rate lipo battery? I recommend you can choose Tattu battery, best power delivery, autonomy, reliability, long life and less sag than any other lipos, and most FPV pilots are using their battery.
I have built many FPV quadcopter, and this is one of my FPV quadcopter’s build parts;

Stinger X210 Racer Drone Build

Stinger X210 is an OPENSOURCE Racer frame that’s so cute. Main body part is 3D printed canopy! If made of ABS or PETG it’s really strong (you can probably stand on it) and you can get a nice finish (more about finish in my tutorial below). It holds FPV camera nicely in place with easy adjustable tilt angle. In the back you have vtx connector mounting hole and good intake/exhaust holes for ventilation. On the sides there are holes for cables and main battery strap.

It has 4 identical arms that can be made in 3 or 4mm CF. I prefer 4mm, but for some weight reduction you can go lower aswell. It has screw “locking” mechanism that allows you to replace arm without disassembling whole build. Arms has also motor ventilation holes (rare!) and motor bumpers. They are wide enough for most “barebone” ESCs. Center will fit the 30.5 and 20mm FCs and below you have room up to 4s 2000mah batteries with OPTIONAL battery protector.

This frame is opensource, that means that you can make it yourself or ask your local buddy with machines to print or cut the parts of frame for you! That means cheap non-profit frame with local spare parts, fully customizable and upgradeable. If you are Banggood or Hobbyking or someone similar, you should contact me first!


Specs:
– Fully symmetrical X
– 210mm motor diagonal
– Quickly replaceable arms
– Very sturdy frame!
– Printable and customizable canopy!
– Really aerodynamic frame!
– Minimal screws and spacers
– Clean build
– Optional battery protector (12gr)
– around 450gr RTF
Opensource rules:
Makers: No commercial selling of this frame without my approval! You can make it for yourself, your friends or by requests!
Modifiers: You can edit files and modify frame, canopy etc. – but please share modified files so others can use them! No commercial selling of derivatives!
Pilots: You can get this frame locally via CNChubs or 3DHubs by sending files OR by asking for parts in this group. I bet there will be makers in your vicinity.
To make your 3D print look cool, stronger and more resistant to sunlight follow this tutorial:


I used for building next equipment, which proven to be good choice:
This selection is quite cheap and turned out to be really good! It flies on rails, power on demand, all acro stuff! No BEC needed, no modifications, less than 2h build time. You also have OSD for voltage and RSSI and maybe some other things if needed.
We start the build with ESC and motor soldering. If you want to make it real good, with low resistance and good solder joint, than you shorten the motor wires than split the wire end and solder on both top and bottom of the ESCs.


We do this on all 4 sets. We make 4 sets identical, because we will change motor direction in software. We also add signal cable and main power cables, that are supplied with ESCs.

Now we can complicate a little and turn the ESCs so that MOSFETS are facing the arm. We will add heat transfer material between the ESC and arm to allow arm to act like heat sink. Well… you can also just put ESCs in the heatshrink and let them cool by the motor air-flow.

Here you can see some of the heat-transfer material, that will also insulate esc from carbon fiber on the arm.

Stinger X210 racer drone build
And shrink over the boom + ESC, to protect it nicely.

We now have 4 finished arms. We make 2 symmetrical arms.

Stinger X210 racer drone buildThis image shows how easily is everything put together. We solder rear 2 escs to the XT60 connector directly, and front pair via Y cable, that is also soldered to XT60 directly. Than we have only 1 more thin wire for FC – directly from 4s. Camera and VTX will be powered also from 4s directly, but via FC, to save some wire.
Stinger X210 racer drone build
Instead of heavy and bulky PDB, we solder everything to XT60 and cover with heatshrink in the end.

Stinger X210 racer drone build
I’ve soldered motor signal wires directly to the FC because I didn’t have suitable connector, but most important is that I made 2 connectors, which I got with camera and vtx and connected them to FC directly (+, – from 4s and video in/out), so I can just mount the canopy and hook up the cables. This is basically it… the build is finished with this
Stinger X210 racer drone build
I have one less quality picture how camera and videolink are mounted inside the canopy…
Stinger X210 racer drone build
To mount the canopy and have battery protector in the same time, I’ll use M3 stud inside 35mm spacer. If I don’t need battery protector, I’d just use regular screw.
Stinger X210 racer drone build
And it’s finished! 2 hours and that’s it
Stinger X210 racer drone build
I’ve found a nice way to shave off some weight and resistance 6-10grams… now I can use battery protector without weight worries 😛
