when you say illegal, is that international law or something?

because as stated before, eastes ( or however you spell it) build rocket car kits for sale in the u.s. and i'm sure if it was illegal the stores would not carry them.

What i did was took an old tc3 and put oneways in both the front and back of it, ran the rockets on the 3rd channel drove the car to about as fast as it could go then fired the rockets off, it was fast and fun for a one time thing but it killed the body and a few other parts from the heat.

actually, not quite sure about that. radar detectors are illegal in the state of michigan. or at least the use of one is. they sell them at any store, and you are allowed to have one. just not allowed to use one. there's lotsa laws that are weird or just have random holes in them

Hobby Central in Poway built one out of an old Schumacher buggy and hooked up a receiver pack to power a steering servo and and parachute. They lit it off a few times in the parking lot after racing one night. It was pretty cool.

But has any body out there made a rocket powered car, like a drag car, powered by those model rockets? Thinking of making one out of redundant spares, thought it might be a fun challenge.

Anybody got any thoughts?

I have built a few. One out of channel, the other out of parts from the tamiya bruser and a sandmaster buggy. Make sure you have the proper angles set for the engine or it will orbit on you.

I built one using an old RC12L many years ago. I used two C-sized rockets, I think they were C sized ... they were the second to the largest ones available for smaller models. I just screwed two L brackets to above the motor mount on the RC12 and zip tied the rocket motors to the chassis. The L-brackets kept the motors pushing against the car and the zip ties kept the motors in place just fine.

I had two huge issues with it .. one, when trying to ignite the rockets from a stand still they put out too much thrust and the car went in circles.

I did not have a three channel radio at the time, so making a ignition channel wasn't an option. What I did was got the car kind of moving by the motor so it had momentum, and when it was at the end of the rockets wired ignition, lit the rockets. The car flew, but running wide open in a parking lot it ended up skipping around and crashing most of the time since the ground was not smooth enough.

I pretty much gave up after 4-5 runs as I was able to get it going faster using just a modified motor and a 6 cell pack. It was fun though!

A heavier car, like a TC3 with more suspension would be more suitable. With a 3 channel radio so you can ignite the rockets while in motion I think you could have a dangerously fast car.

Imagine a TC3, with five D sized rockets lit in stages. OMG you'd have a land missile.
