Da… It’s back. Now it arms and runs until I lower the throttle to zero and again gives no RC receiver and failsafe. then the motors rev up and the APM freezes leaving the motors turning. No way out but to pull the plug. That would be a fly-away with props. Tlog and rlog were there but not transferred from logs folder to quadcopter folder and gave download errors and could not be downloaded … So no evidence.
My new APM 2.6 arrives tomorrow…
