Need help with my LUNCH BOX

Post by Bellagio »

Hello. New R/C guy here.
Totally late to the game. I always wanted a LUNCHBOX as a kid. Finally bought one. Sadly, I cannot get it to work. Anyone have insight on what to do to get it to work correctly?





Thank you!

Your steering servo appears to be plugged in backwards, the yellow wire should be on the inside pin.

Does the truck roll if you push it?

I would take the motor back out and see if it works as normal outside the truck. If it works fine then I would say something is binding in the driveline.

That's really odd. Does the steering servo work when you turn the wheel on the controller? If so, that eliminates a connection issue between the transmitter and receiver, which was my first thought. It sounds like the motor is trying to go but is binding on something. I agree with Rc10th, take the motor out and see if it work outside of the car.

Any chance the motor screws are too long and binding the armature? Cout something be binding the drivetrain such as a popped driveshaft or something in the gearbox? Lipo looks like it is selected on the ESC, are you above cutoff voltage?

UPDATE:

Thank you.
The problem was that the brass gear on the motor was rubbing against the housing.
Fixed the problem and now the truck is FIRE!
