Yup, had that happen also. The bearings they use are not the best quality. I've had one destroy itself.

Im going to reassemble it all and give it a test now if it still wont work im lost

I have fixed the issue but now i have noticed that the driving wheel on the left moves beyond what the gears move by like 0.5cm while the other side doesnt do this. Is there a easy fix for this or will i have to unscrew it all again? Thank you

Here is what is happening to the driving wheel on the left now.

That final gear may be press fit on the shaft or there is a pin holding it in place. I know I've drilled and tapped holes in the collar of that gear and added a grub screw to better secure it.

Like my fellow members, I need photos to learn more. When you say the "Combined" is missing, I think you're referring to the radio? But are there any electrical components already? Such as motors for the tracks, turret rotation, etc.? As for brands: Heng Long, Taigen, Torro, etc. It's strange that it's empty.

The small knob on the top of the Transmitter on the right side . That will track the tank to one side is its been moved.
I dont get it, that thing is a good as it could be when I sent it back.

It would've occurred over the 7 times i used it for about 3 hours after you gave it back to me, i was driving it pretty hard to so its not unexpected the gearbox that i was thinking had issues finally stopped. As well the motor is loud but it isn't the motor its the gearbox, as i found out yesterday after doing some tests. But i have seem to have fixed it except for the video up top were the driving wheel rotates about 0.5cm past when the gears stop.

Well im not to sure what i did but simply unscrewing the gearbox and re-seating all the gears has fixed the issue. Just ignore the fact i put on the tracks wrong 3 times.

Took it for a test drive with the new heng long smoker i had to jam into it, and the motor actually died. No movement no anything just dead. The smoker works atleast i guess. Im starting to think the tank is REALLY cursed. Could only drive in circles.
