no power from the engine!
hi i've just bought a thunder tiger ts-4n sport and it has a bit of a problem.
when i got it, it was 100% built so i decided to start braking in the engine.
once it started i noticed that it revs right up but the cogs do not turn.
when i try to move it accross the floor there is quite a bit of drag.
any ideas whats wrong and how to sort it.
