Hey there, I have some questions regarding your motor driver and motors. I apologise in advance if they are to simple or patronising.

1st are you using an AWESC dual channel motor controller, found here?
https://www.arc-robotics.org.uk/prod...ed-controller/

Those esc's use DRV8848 dual h-bridge motor drivers and has over current lockout protection when you exceed 2A on one channel. Did you buy those motors with the ESC or separately? Are you motors drawing more than 2 A each? (that may not be the case as those i have never seen those type of motors exceed more than 1.6A at stall, which is not the case for you)

I assume that you have soldered everything yourself? Just double check that there are no tiny bits of wire or flecks of solder between the motor contacts. It can be the most minuscule bit ever but that will be enough to short circuit a motor and put you in over current lockout.

Also have you bought a mixed or unmixed ESC and are you using mixing on your devo remote?
