I have a 1/2 scale cardboard Lamborghini that I want to make remote controlled. Except, I have absolutely no idea how to start.

The only material used is cardboard (and hot glue). It is a paper-fold model blown up to 1/2 scale.

The size is 7 ft by 3 ft by 20 inches tall.
not sure on the weight but around 20lbs.

I have absolutely no interior components, its just cardboard.

I am also limiting this to mainly indoor use. or paved surfaces. nothing off-road.

I plan on building a rough frame (probably aluminum) to mount everything on. I have no need for suspension or anything complex. I plan on building my own steering system and I need something (servo, motor, etc) to turn the steering axle. I also need a drive system of some type (probably just rear wheel drive)

My biggest problem is understanding the way the RC transmitters work and hook up to the RC car.

I am a complete newbie and just require whatever help I can get.

For something that big, the cheapest alternative would probably be using a cheap go cart as the donor chassis and stretch that chassis to fit. I'm not sure how you would set of the steering, but the throttle and broke would be an easy job.

In the end though, you'll have an expensive rc go cart that will destroy that cool cardboard body the second it brushes up against anything.

Cool body and interesting project....

In my opinion, a go kart chassis would be overkill for this cardboard body. I do agree that as soon as you hit something, it would ruin the body, so I would think fabricating a pan car type chassis with an electric motor system would be the way I would go.

Since it would be just for show (I am assuming) gear it to be very slow to avoid crashing into things. You'd probably want to make this thing as light as possible too so you can transport it....

How much does it weigh?
