Hi I bought one and sadly it wouldn't work when I took it to a reparator he said the engine is dead I wonder if you know what can I do to fix this problem. Thank you
You can easily replace the motor if that really the issue. Check price of the motor at your local or online stores and if you think its worth it then replace it. Remember that you may need to solder the wires and re assemble the gear box. The provided motor is of a decent quality so may be you got a defective product? In most cases battery will be the problem.
