So I just picked up an SC10RS in RTR form. I had it out on the track for the first time yesterday. I had a couple breaks that we're fixable (hinge pin on the front caster block/a-arm came out, lost the spacer, and rear upper shock tower nut came off).

But, I have one problem I have yet to figure out. Occasionally the car will lose all power to the rear wheels momentarily, about 2-3 seconds, then it comes back. I can still turn the wheels but there is 0 throttle response for those couple seconds. This usually happens when landing hard after some doubles, but it also happened on smaller bumps. I doubled checked all the electrical connections as I thought something was being knocked loose on the landings, but found nothing wrong. I am using all the stock electronics that came with the RTR kit. Any ideas what could be causing this?

Thanks.
