Default Pulse jet buggy

Ok, so we all know that sometimes RC is about doing stupid things. Well, I've come up with an incredibly stupid idea. Hobby King just came out with a pulse jet and I want to mount it on a buggy. I got hold of an old hyper 8 nitro chassis so I can have some brakes (like that'll matter) but I'm trying to figure out how to cut the fuel remotely so I can kill the engine. Any ideas?

What about a valve in the fuel line that can be opened or closed by a servo?

That's a good idea, but how would it be done?

Well i was thinking that you could pick up some small brass valve at a hardware store. Then on the arm drill a hole to mount a ball stud. Mount that all up and connect to a place on the chassis. Run a link from the valve arm to a high torque servo. Done. Just run the fuel line through the valve.

Any reason for a pulse jet car? They are loud and inefficient.

Because it's a jet car! Turbines are expensive and this just seemed like something cool to take to races and show off. The valve idea is great but it might be hard to find one that small.

Those pulse jet engines are wicked. The history behind them is something else! So cool but yet so evil. Jimmy

Lol, this will be good, just be aware, a pulse jet and alot of the engine, get cherry red hot. So everything close has to be heat resistant. Check at the hardware store in the gas fitting for a cutoff. Then tie it into a servo that is away from the fuel line somewhat. WAY louder than a nitro lol.

Lol, good point, I think these are all or nothing engines. Controlled by cutting the fuel. But sure would look good for a minute lol.

I take that back, you do have some control of it, but how much I'm not sure.

You only live once. The duck pond is surrounded with short green grass so it won't burn lol. As long as it's caught on video it'll last forever.
