Cheerson CX-20 OpenSource Intro & Hacks (Stability issues RESOLVED!) I purchased an Inland CX-20 at Micro Center, which is the Cheerson CX-20 Open Source version rebranded in the US.
I had learned to fly quadrotors with a SkyViper M200 nanoquad (similar to CX-10), then the Hubsan X4 H107C, to ensure my fingers, reaction time, and piloting skills were up to the task before flying a bigger more expensive quad. Xiaomi Yi Enhanced for FPV'ers (Superview Script) The Xiaomi Yi camera is really great when it comes to value, but it lacks in quality of video.
This is not a hardware issue, it is a firmware issue. The Xiaomi supports "scripts" that can modify the firmware, to unlock it's full potential, yet in a safe way with no risk of breaking the camera. Turnigy Multistar 20A Slim V2 ESC With BLHeli OPTO 2-6S. MultiStar ESCs are are a quality speed controller at a fantastic price!
Designed for simple installation and easy setup these ESCs have proven to offer excellent performance when used in Multi-rotor applications. If your starting out in Multi-rotors and need an easy to install solution that is tested and proven to work with Multi-rotor craft then these speed controllers have you covered. These ESC's features a very smooth yet linear throttle response, without sacrificing a rapid, crisp, response to any throttle input. APM/Pixhawk Tips for Good Loitering. AirbotPower. Airbotservices has been passionate at understanding and documenting ways to power flight controllers to ensure redundancy and maximum reliability, especially in conditions where a 4S 3DR power module (or similar PM) can’t be used: battery voltage above 4S and currents above 90 amps.
We published a how-to guide on this topic on diydrones a while ago, wrote documentation in the wiki and on the PX4 autopilot site: We’ve got feedback from some who are not at ease nor have the necessary engineering skills to mess around with soldering individual electronics components, cables and connector adapters. We therefore think there is a need for proposing a high quality reliable plug and play “Power & Measure” solution, working also for higher voltages than 4S batteries. AirbotPower solves the problem of powering a UAV and measuring current & voltage in a most high quality, reliable, redundant and efficient manner (extreme low voltage ripples, low noise, low EMI, MHz switching frequency). AC: reducing twitches in Loiter, RTL. Leonard and I spent the past few days getting rid of various twitches.
CX-20 Cheerson Auto Pathfinder - Page 1603. Quote: CIRCLE_RADIUS Defines the radius of the circle the vehicle will fly when in Circle flight mode.
HDOP 230 is 2.3 , the value of which it will allow take off in GPS dependent modes, defines what it considers to be good position value for GPS, also used for per arm checks, I.E. at or below this value it will allow take off in GPS modes. INS_PRODUCT_ID 0 = unknown(Chinese half backed copy) LOITER_LON_I Loiter longitude rate controller D gain. Compensates for short-term change in desired speed vs actual speed LOITER_LON_IMAX Loiter longitude rate controller I gain maximum. RATE_PIT_IMAX Pitch axis rate controller I gain maximum.

SimpleBGC: How the "Follow Frame" mode works. EasyCAP drivers for Windows 8, 8.1 and 10. The EasyCAP converts an RCA or S-video source into a USB video and audio capture device – known as a Sound, video and game controller device in Windows – the possibilities for connecting analog sources to a Windows machine are endless and it’s priced insanely cheap.
All of this positive feedback stops when you connect it to a Windows machine – XP, 7, 8, 8.1 and now 10 – and realise there are hundreds of variations of this device produced with drivers designed specific to each variant with no original manufacturer to provide drivers or compatibility… at this point most users bin it and go on with their lives… I almost gave up too… After a fortnight of driver hunting, driver conflicts, BSOD’s from resource conflicts and even ‘Windows driver paywalls’ – where you have to pay to download drivers for the EasyCAP – I got ‘my’ EasyCAP working as a video and sound capture device in Windows 8.1 (and Windows 10)!

What is Pixhawk 2? Pixhawk 2 is a small cube, with a 38.5mm square footprint.
All connection to the cube is via a DF17 connector coming out the bottom of the cube. This modularity allows for multiple form factors to suit multiple platforms. For the stand alone market, it will be coming out in two form factors to start with, a "Full" configuration, and a "mini" configuration. The full will have connectors for everything, the kitchen sink.... DJI F450 Flame Wheel Lighting 100kph 62mph flight with 3s lipo part #14. Motors for Multi-rotors T-Motor MN4006 Antigravity Brushless Motor (380kv / Storm Edition)
* This is the motor used in Storm Drone AntiGravity, they are the same with ordinary T-Motor MN4006, the only difference is that they have the Storm logo printed on and they came already soldered with 3.5mm bullet plug, this saves you some work.
They came in normal black paper box instead of colorful gift box. Longer flight time and better handling, just like putting a high performance engine in your car T-Motor makes the ultimate motor for drones, with their motors you can carry heavier payload and have longer flight time, this seems too good to be true, but yes, they can! T-Motor gives you such outstanding performance because they have are much more efficiency than others, they are good in turning electricity into motor rotation, less heat, less energy consumption.

Quadcopter-Robotics: APM Power-Module install. My first APM Power-Module (PM) install.
This one has a BEC, but I'm not using it yet (still using Nova's PDB). I carefully removed the proper pins from 6-pin PicoBlade and inserted into 3-pinner. Black Sharpie marks the Ground pin. Upgrading firmware to 3.1.5 (Cheerson custom Uart version) I'm finally upgrading to ArduCopter v3.1.5. VinnieRC took the time to re-compile a custom Cheerson Uart version of v3.1.5. Now, Telemetry/Uart port works on this Cheerson_v2.52 Flight-Controller. I installed it from MissionPlanner v1.3.27. .
