I just finished the initial build of my very first arducopter (the Y6 DIY kit)... however, I am unable to get it to arm!
I do not yet have the GPS/Compass as it is backordered, but everything else is installed.
I have successfully calibrated the ESCs, I can see the control sticks input in the Mission Planner and have configured the Frame Type, Accel, and Radio. However, I cannot get the APM to arm in order to start testing my motor directions. All the motors turn at the end of ESC calibration.
**EDIT: I can successfully use the "ARM/DISARM" button in the MP (via the telemetry radio) but the APM disarms itself after several seconds. I was able to use the short periods of forced arming to get my motors wired correctly... but I still can't arm normally or keep it armed artificially.
