My traxxas vxl3m esc died !!

[speedy]

Hi !

On the second pack my vxl3m esc cutoff the motor because the lipo was emty so i put a new one in and the truck(1/16 summit) ran great for 20m and landed on it's roof and then the motor died ? Why ? I geared my summit 16/55 so that chould be ok to run on 3s right? And the thermalcutoff didn't cut the power in two stages that the instruktions says! It just died!

I,ve tried another motor with the same result ! Dead motor but with the servo working and the esc reacts on throttle input but wount spin the motor !,
