I am trying to revive and old 3DR APM 2.5 quad mostly just to see if the motors and frame can be used if I upgrade it to a Pixhawk. I still cannot get it to arm and stay armed long enough to lift it off. If I force it via tablet/telemetry radio it immediately goes to disarmed.
I pulled it apart and re-calibrated everything. I went through the motor test successfully. ESCs are calibrated (although the all-at-once is a little confusing) The tablet says it is locked on to 10 satellites. Battery is full.
1) Can I find something in a log file that will indicate why it is failing?
2) Is there a way to just force it to lift off? Just want to see if the ESC/Motor/Frame is still usable not fly it.
