Gear Problems

I just got my 3,8 today and it seems to run very fast, but the gears don't seem to mesh properly. I am having basically the same problem as some other people have had. The car requires a push to start moving, and even after turning. Anyone have any idea what could fix this? It's really disapointing because I was looking forward to trying it out.

Try cleaning all the gears in denatured alkahcol and then clean the rear axel with your hands. Hope this helps!

The 3.8 motors draw more current than a 1.0 or a 2.2. The battery inside the bit may or may not be able to power it.
