Ok i have a nitro sport with a .18 engine in it. Car runs fast as hell, I put new bearings in the cb gear about 8 tanks ago. All of a sudden the car stops moving. The engine is spinning and the flywheel but the cb gear doesn't. I took off the cb gear and the bearings and the clutch all the look good. The CB gear wa very hot but I don't know if its supposed to I never noticed it before.

So are my bearing toast or what, even though they are fairly new.

they could be do they spin freely whne u have the engine out and the cb is on the shaft with the bearings and or your clutches are toast and your springs are touching the cb causing the heat

the bearings spins very fast if I spin the cb by hand. If I spin the cb it will spin for a good 20 seconds before it stops. I have to check the clutch.

well it looks like your clutch pads are toast

Check and make sure your flywheel nut is tight. If it is then you defiantly have a clutch problem. Are your shoes grease free and is the CB clean?

Can it be that your clutch has been reasembled incorrectly since you replaced the bearings??
