Of course it can be done but it's up to you how you do it.
It will take time and patience, trial and error.....

I would start with making a chassis from an aluminium plate and work out how to attach the motor to it.
It will need to be secured well to the plate in a few spots.

Once the motor is done work on the rear axle and transmission.
Sprockets and chain is the easiest way.

Are you familiar with gear ratios?
You'll need to gear it down it to about 6:1 to 8:1.
A 6:1 the motor turns 6 times for every turn of the rear wheels.

You may have to replace the springs in the clutch to get the revs up higher before it engages.

Depending on what size wheels you're going to use you'll probably have to do a dual chain and sprocket setup, otherwise the sprockets will be too big.

I've used angle grinder heads a few times as gear reduction, in combination with sprocket and chain.


The steering will be tricky.
Either build it from scratch or use something off an old RC car.




It would help if you posted a couple of pics of the motor and other things you're going to use rather than just asking "How do I do it?" as there's no magic formula for building a home made RC car

What sort of machinery have you got access to?
Welder, lathe, drillpress, benchgrinder, angle grinder, jigsaw etc etc?
