Hi, just wondering if anyone knows the answer to two problems that my different RC Cars are having. The first is the rear wheels of my RC Car are stopping and starting really quick when I drive but the front wheels are running perfectly fine. They also shake around a lot. The second problem is my RC Car is when I turn it on, its fine but as soon as I turn either way, it starts making a really loud noise and your cant turn anymore. Please help!

Also, if anyone know where to find a rear tail shaft replacement for a WPL C24-1 , that'd really help! Cheers!

What car and electronics are you running? Which electronics are you having issues with? What you have asked is kinda hard to follow. I just trying to make it a little simpler to guide you in the right direction.

Sorry. I dont know much about this stuff but I know that the car is the WPL C34

The box says that its a 4 Channel 2.4GHz car. I dont know if that'll help.

Is this what you have?
