i think i might make one out of copper (will that work?). i might use two 12 gram co2 adaptors with some 1/8'' copper pipe to get the co2 to the motor and a ball valve to control the flow. i think ill use a ball barring for the ball and a bolt to push the ball up. then maybe a bushing that the ball barring sits on, it doesnt have to be a 100% seal doesnt it? it looks simple enough, i remember wanting to make one because i used to have an air hog, i almost kicked myself 4 years later for throwing it away.

there was a size of copper end cap that fit perfectly in another size of copper pipe, does anyone know that it was? i think it was 3/4'' end cap in a 1'' or 1.25' pipe, but i really dont remember.

will copper pipe stand up to the pressure?

HOLY MOLY. Meatballs our minds must be linked together or something because I was thinking about doing the exact same thing yesterday. That is why I posted that topic about liquid nitrogen.

I was planning on making a steam engine type motor to run on compressed air but I dont have the right equipment or tools. I would really like to see what you come up with if you ever build this. Good luck

hi i did the exact same thing. used to have an air hogs airplane. loved it. then the wings broke for good after hitting its thousandth tree. i saw no use for it and threw it away. now i REALLY wish i didn't. No it doesn't have to be a perfect seal, and if you use a design similar to the diagram on page one of this topic, a small leak might be better than a perfect seal since it would compress air on the way back to the valve assembly at the top. not sure about that one, but i know it doesn't have to be a perfect seal. i've thought of the end cap idea, and a 3/4 inch pvc cap fits perfectly in 1 1/4 inch pipe (w/ o-rings) but thats the wrong material and sizes. i like the idea of an end cap though.
SpudBlaster15 what did you make your engine out of? i built one using that principle out of legos. hooked up to a vacuum cleaner it got to a maximum of 860 rpm (measured with a tachometer).

Also, does anyone know what presssure an air hogs airplane runs at?

mine hade a gauge, but it was just green, yellow, and red, but i was 10 years old and could pump it and the chamber was only about as thick as a 2 litter bottle, so my guess is 50-70psi, and it ran for about 45 seconds- a minute. Thats what i remember, it could have been longer. i remember i had two, one flew much faster than the other, but they had the same motor.

yeah, mine had the same gauge with min and max pressure measured. i still have the pump, and i suppose i might be able to get it hooked up to a gauge or something. i might try that. it would be a pain tho, since its not a standard sized thread or anything. I'd like to find out some easier way.

i dont remember what i was the threads/ fill valve was, but just use a hose and hose clamps, for 60 psi you really dont need threads.

good point, didn't think of that. i just want to get a psi valve on there so i can see what 'max' is in psi.

The air hogs firestormer airplane runs at 80 psi (it says it on the back of the box)
Also, I found out that you can unscrew the engine from the tank and screw it onto a coke bottle. The threads are perfect and it has a perfect seal.

Right now I'm having amnesia and deja vu at the same time. I think I've forgotten this before.

It could power a car if you make it big enough ;)

So someone that has got one of these motors or an air hog one. How long do you think it would go for on a 1.5L coke bottle at 80psi?

My engine was machined almost entirely on a lathe and a vertical mill using brass and steel stock.

hmmm, well that wont work for me as i have neither a lathe nor steel and brass stock. that's truly brilliant to put an air hogs engine on a coke bottle, how long does it run like that? does anyone have an air hogs motor that they dont want/need? i might post something about that in the classifieds...
