I and a few others have noticed some weird shifting of the gears (even with the alloy plate) in the 05 v2. At the end of a race sometimes, my car will be squealing with poor gear mesh. Back at the bench, all it seems to take to fix it is to loosen, then retighten the motor screws. Seems to be an exclusively v2 issue, for me. I'm on my third gearbox now.

This brings up a question. Has anyone tried attaching the motor directly to the motor plate, bypassing all the plastic bosses between the outside and inside of the chassis? You'd have to remove the bosses, but there would be a more solid mechanical mounting for the motor. The only downside is removing the motor would be more complicated. Then again, it'd be one less thing to remove to get into the gearbox.
