How to I attach axles and wheels to a rubber band powered car?

I need to build a car for a Science project. I need to create my own energy but I canot use elecricity or push the car in any way. I decided to do a propeller and rubber band powered car. Everything is going fine except I‘m not sure how to attach the axles and the wheels to the car. When I try to attach them, they won‘t spin properly and the car doesn‘t go very far. Please help me! This is urgent! Any suggestions are great.

Answer:

Staple the axles maybe. Wheels can spin freely on the axles, right? If axles have to turn, you need some sort of bushings mounted with bushing U brackets, I think.

Most importantly, you'll need a way to regulate the power. Maybe a transmission from a toy electric car.You'll also need a way to wind it up without losing the existing windings. Wheels and frame can be copied straight out of any remote controlled toy car. In fact, if you replace the electric motor with the rubber one, you could just do a straight conversion, giving you an R/C rubber band car!
