i have some strange problems while trying to get my Quadcopter up and running. I have APM 2.6 (the Kit offered by 3dsystems) and a Mac. As RC i am using the Spectrum DX7 with AR8000 as Receiver. I have a Mac with APM Planner 2.0 installed (+avrdude). The first problem is: i cannot flash from APM Planner, but it works through the Arduino IDE. I can then connect the APM Planner to the drone via USB and run some tests, but for instance the motor test is activating only two out of the four motors. I can run the RC calibration test through command line and get calibration results, but it does not work through the graphical interface (bars are not moving). While playing around the drone suddenly went on and all four motors were spinning. No clue how that happened because i cannot arm it through the RC (or do ESC calibration etc.).
Any idea of what is going wrong?
Thanks in advance,
