Orion r10.1 esc repair

[Zippy G]

HI all
as per the title, is there anyone out there who is able to repair an orion 10.1 that has been connected backward polarity for a split second.

Now the esc powers up, when the trigger is pulled for the throttle it blinks a red light, if you manually spin the wheels at this point the esc runs fine until you bring the buggy to a full stop again. then it will require a bump start to get it going again.

Any help would be appreciated

Regards Sam
