Look on Google. We use one similar to
this. If you can find one that's a bit larger (1" or 1-1/4"), even better. The most important thing is that the valve (and plumbing and tank and fittings and so forth) is rated
for air, at a higher pressure than you're using. A large valve (3/4 NPT or greater) is essential to get enough air out fast enough to throw a t-shirt very far without using pressures higher than we're used to in FRC.
I don't know what takk you have in the model, and we don't move our barrel vertically, but control range using the time the valve is open, so I'll pass on the other two questions.
