Thanks KK some diagrams would be helpful, I've taken it apart but I don't know which board controls what....
I need to buy a transmitter for it, or is it possible to use a planet t5? Also 1 of the gearboxes seems to be sticking, turning by hand every few rotations it locks up, wiring a battery directly to the motor it works but 'pulses' as it forces its way past the point of locking... not sure what else might be wrong with it and can't check until I can turn it on and try using the controls to see what works and what doesn't.
Thanks I'll check that link out tomorrow, off to work now :(
