I have a problem that I cannot seem to resolve. I am unable to arm my quad so that I can fly.
My set up...
A 3D robotics quad
Spectrum DX7s Transmitter
AR8000 receiver with telemetry installed.
Mission Planner 1.2.70
The APM will not arm. After APM boots I wait for GPS lock (LED solid blue) I hold the throttle at low and to the right. The RED LED changes from flashing red to solid red momentarily then goes dark.
Troubleshooting that I have done and attempts to correct.
1- Clean install of the firmware on the APM.
2- Calibrated radio multiple times.
3- Calibrated ESC's procedure works well
4- Trims on controller have no offset and the "rudder" is set correctly.
5- Tried a new clean model on the TX and rebound the Receiver. (repeated above)
I have run out of options and really need some guidance.
