the little grub screw holding the pinion gear wasn't tight enough
Classic :)
One thing I did notice is that it's reluctant to go in reverse. From rev to fwd is fine, but if I hit rev from fwd nothing happens, any ideas?
Probably just activating the brake. From forward hit reverse, which brakes, then go back to neutral then reverse again in quick succession to quickly get it in to reverse. Probably won’t do the gearbox much good though :)
Excellent! Brake confused me to start with, depending which esc you have, you can alter so you have f/r, f/b/r, or, f/b. Bit of thread lock on the pinion grub screw always help too.
