Arm, then immidiate disarm

my quad is acting up

it arms, and then as I apply throttle it disarms.. Sometimes goes into failsafe land mode

Data logs show a mix of

ERR subsystem 2 ecode 2 (cant find any refrence to s2 e2)

and

ERR subsystem 5 ecode 1 (failsafe radio)

I checked the flashdata logs  (rcin -  ch3) and throttle never dropped below 1000 infact as the throttle was climbing when the error occurred.

Additionally I noticed that my telemetry link dorps to like 25% then climbs back up slowly.  even though the drone is on my desk in front of me... But the usb link is stable. Wierd

  • Seemed to be a power drain on the APM.  I disconnected the 12 Leds attached to the drone and the problem went away.

    Weird enough that the issue did not exist earlier. wonder what caused it to pop up now.  I added a Step Down converter and am powering the lights from that now.
