Overheating BEC?


I’ve almost finished setting up my CopterX 450 Pro (TT) which has a 50A ESC + BEC - http://www.ehirobo.com/copterx-cx450-10-05-50a-brushless-esc-with-bec.html

I am having an issue where the BEC feels incredibly hot after a little while and stops using the input correctly (it receives inputs in a laggy fasion). Eventually the APM -> Servo communication appears to lock and won’t work anymore.

I am using a power module connected to the APM and the helicopter is stationary - any ideas?

If you are using APM 2.x, disconnect the jumper cap of the power switch between the input and output ports
