2 Issues with my RC8RS!
 

So recently picked up my first nitro rc and all is great so far. I took it out today for the second time and ran through 2 tanks today.

One issue I noticed near the end, one of my front wheels wobbles as the car rolls forward. I noticed it when I drove the car towards me with very little throttle.

The other issue, every time the car bumped/crashed into something the receiver went dead. I would have to remove the body and open the receiver box and wiggle the batteries and unplug and replug the connections on the receiver. After doing that, it would work fine until the next bump. Same thing repeated about 4/5 times today.

What should I inspect or replace?

Anyone have a cheap source for glow plugs? McCoy?
