Great, Join the Club.

I have read through a lot of the old threads but am still left with some questions.
Who doesn't?
I still don't understand what the stroke and the bore mean?
Like in combustion engines, bore and stroke are what make up the volume in a cylinder.
Stroke is the distance the piston can travel. Bore is the diameter of the piston (and that is the same as the bore -minus a few 100th of a mm- of the cylinder it travels in). Diameter dictates the surface area. In case of a normal cylinder that is Radius (half diameter) * Radius * Pi (3.14 to be fast).
Surface of piston in cm² * pressure in bar = force in kg.

Also I remember seeing a link to a great website on pneumatics in combat robotics but I can't find the link, does anyone know what it was?
Several websites qualify in that respect.
But for Robot Wars, I have posted these in the past

I was also wondering if you really need a buffer tank because due to my design i can only fit in either 1 main tank and 1 buffertank or 2 main tanks which i think i will need to get plenty of flips(i am thinking of
Using p16oz paint ball gun bottles)
Hannibalito III uses a Full Pressure setup, Cutlet/Gravity style with 12 oz main bottle and a buffertank, still we achive 15 flips or better. Amount of flips depends on stored CO2 and volume of cylinder.
I doubt that there is any feather using 32oz CO2.
An option is to use a 16 or 20 oz main bottle and a reasonable buffertank. I aim for 3 times cylindervolume in the buffertank.

I am sure that more questions will follow soon but thanks for now.
Please do.
