Tail rotor question

Raptor G2
ok so ive spent the last week trying to sort out the problem with my gyro not working (so i thought and the local hobby shop) my heli spins in circles. ive just noticed after removing part of the rear rotor assembly that the toothed wheel that the belt goes around spins independantly of the shaft that its fixed to Is tis correct? Is it a case that you have to tension the belt enough to limit this splipping. then why does the belt have teeth.? im guessing and hoping that this is why my heli spins (not enough torgue on the tail rotor) im a total newbie so would app any help

try this, By hand, turn the main rotor in the proper direction while you lightly hold the tail rotor. The tail must turn out of your hands while driven by the mains.
