Do you need two motors to run two different wheels if they are across from eachother?

I don't have power functions an I would like t use them

Anyone, please help.

@ncstupidaccount No, the 3rd set of wheels have a differential gear inbetween then which is connected to the 6 cylinder engine in the original model. All I did was take out the engine and replace it with a motor...

to make it drive did you use a Power Functions XL motor, and to steer a M motor. Also I was just wondering if I could make The Lego Silver Champion remote control with motors etc. But I don't know what I would need to buy. please could you tell me.

@MBUK1000 I don't know either. It's just a case of getting the parts you'll definitely need like a battery box, remote control, receivers and motors and just trying it out. It will take a while to get it perfect. This model wasn't perfect... I could have built the motors into the model but I didn't take the time...

A good website to buy parts from is bricklink

how did u make it driveble did u put the motor with geers straight to the beam wcich let the motor spin or did U build a whole new chassis??

[lorirocks777]

@1994smeagol19942  I just added the motor where the 6 cylinder piston engine was and geared it down a bit... Does that help? It wasn't too hard to put in.
