Model Rocketry

So I bought some parts and started cutting/assembling the shoulder-launched model rocket delivery system that I posted the ideas for before.

Some basic questions that have come up:

What type of battery do these things need? Will a 9v work, or do I need to go bigger?

I prefer to not have my face burned so what is a good length for the part of tube that extends in front of you that the rocket won't burn your face? I will have a face shield and a paintball mask on but just to be sure, how long should it be in front?

Again, not going to be a weapon.

One for the base and one ring. The tube will have connections to connect those two strips to close the circuit. All you'd need to do is push the button.

 Exactly what I was going to do

Except I bought some t-shaped pipe so I can just take out the plug, send the rocket down the front, and wire it in the middle.

Do you think a 9v would still would or would I have to wire 3 AA's together?

The rocket launcher, face mutilation or both?

There will be pics up tonight.

Firing is a month away when I go to my cottage in Wasaga Beach after school. (beach=safer)

I only have about half the parts bought including a red dot for random coolness.

The month should give me enough time to raise the money to finish it. My goal to never work retail has it's ups and downs.

Propane powered gatling gun?

Do you think that this design will fly straight while fired horizontally? What would you change?
