I have built a rocket car, yes, I said a ROCKET CAR. It is built all out of
wood and PVC pipe. It has a 2x2 chassis, a luan body, and PVC engine mounts.
It holds five E engines and they all launch at once which gives it a lot of
thrust. It is going to have 6in wheels, which we took from a model airplane.
It is going to be a tether type car, meaning go in a circle, and be held in
that circle with wire. The wire will be held onto the car and the other end
will be attached to a midpoint of the circle somehow and the car will spin around
the circle. The circle should be probably 20 feet in diameter. If you want plans
(if it actually works) you could contact me and I will mail them to you.
