id probably need something around 30-40mm bore - any higher and i probably wouldnt get enough power from the compressor for it to work properly.

id also need either a pressure relief valve or a pressure switch, but i dont know which would be best to use.

Later in the year i may also be looking to upgrade to CO2 - as this is my first flipper robot i dont want to go straight into the deep end! id prefer a ram that could be compatible for both systems but it doesnt really matter if not...

Unfortunately the first event i am going to this year is Brugess Hill, where id want to be competing with the robot
