Thunder Tiger SSR does not move?

hello, my thunder tiger SSR starts and revs up ok but the car does not move.
the weels are free of any restrictions and all the cogs/cams spin when
the revs rise but the wheels do not spin
any ideas what could be wrong?

Try red bull in the tank.

Broken or missing gear somewhere.
Take it back for warranty repair, replacement, or refund.

Download manual http://www.acehobby.com/ace/PDF/Car/SSR-SSBmanual.pdf "all the cogs/cams spin when the revs rise but the wheels do not spin" indicates the clutch is functioning. Most common fault is a loose grub screw.on one of the drive dogs- check all. Otherwise, check whether the main shaft is driving, if not = fault in center 2 speed gear unit - clean the one way bearing or a broken gear in differential. regards Alan T.
