RunCam 3 - User Feedback

Recently bought this RunCam 3 box style HD camera for FPV and regular use. I also 3D printed a cover for it. Thanks for Barspin who contribute the 3d design. Here is the link to the 3D Design. Here is the RunCam 3 manual.

So far, I feel the picture quality is great or even better than my old GoPro 3. The cube size is perfect for putting anywhere I want to. For FPV, it is easy to wire the cam to video transmitter.

Auto Pilot RC Drone - ArduPilot APM 2.8

ArduPilot APM 2.8 setup:
  1. Download Mission Planner from here. Mission Planner documentation can be found here.
  2. Connect the ArduPilot APM to the computer via USB cable.
  3. Open Mission Planner, select the comm port then click "Connect".
  4. If not working, go to Device Manager to update driver using driver under Mission Planner folder.
  5. Download firmware to the board (don't "Connect" to mission planner). Mission planner will automatically download the firmware from internet and upload the firmware to the board.
  6. See the wiring connections between the board and the other hardware. Here.
  7. Calibrate the board, radio and ESC. I skipped the ESC calibration. 
  8. Select flight mode. Flight mode descriptions are in here.
