Now that I have figured what I am going to do for the drive, I plan on building a FP flipper. I have been studying various sources about pneumatics in combat robots, namely Team Hurtz site and Team DaVinci's Understanding pneumatics.

I have a few questions:

1. What is the general size for a HW CO2 tank?

2. What is the general size for the buffer tank?

3. Where is the best place to buy pneumatic parts?
