Chris, I trust your judgement here. I've not done the math myself, nor have I
created a 2 Liter presure tank.
It must be time for me to create a compressor using the RC racers motors. They
eat a lot of power, so they have to be run by battery box, nit RCX, but that is
fine. If I want to run things via the RCX, I can just use a motor and a
polarity switch.
I'll have to test it after I make it.
