4 shots isn't much... you should think about stocking extra tanks or using a larger air tank or something.

It actually gets more than 4 shots. If the tank is filled up to around 110 psi we get 4 long shots. After this the psi is still around 60 which allows for around 5 more mid range shots. For the parade we recently had it in we only need to pressurize the tank a couple of times during the mile long parade.

You can also probably get a lot more shots by lowering the time the solenoid is open for when you don't need 100 feet. We had a 5 gal tank @ ~120 psi that fed through a regulator into a 1 gal tank @ ~60 psi and we were able to get 8-10 shots at >50 ft (not even completely optimized) before dropping below 60 psi in the main tank. By my calculations, your tank is ~ 9 gal, so you easily have the energy to get well over 10 good shots, it's just about how efficiently you use it.

Right now we haven't done anything with controlling the solenoid. its controlled with how long you hold the button. A really quick tap is all we use to fire at the moment. Later on we will hopefully be adding a way to control the amount of time the solenoid is open. This robot will be going through many changes as we learn and experiment with it!

@Ginger Power

Do you have a website for COR? This would be a great place to post it:p Just saying!

Technically there's a website, but it's such a work in progress that there's almost no reason to post a link. Here it is anyways.
