  1. Currently using a 7.4 Lipo in my 552 but have brought a mini 9.9 LiFe which is the same size but slightly thicker than a mini 8.4 nimh. As most Sig owners know battery space is an issue but does anyone know if fitting the Well RIS or other types will give me a little bit more room for the LiFe to fit?

  2. Right im currently running a pretty much standard internals in my gearbox apart from poly piston + bearing spring/piston guides on what I believe is a m90 spring that came with the gun. (ca Sig 552)

    With this and a 7.4 30c Lipo on dean's I'm getting a constant 330fps with an rof of 16rps.

     

    I am wanting to up my rof to around 25 max but would like to maintain or even up the fps to 350 but without getting a bigger battery. I know I will need to short stroke the piston a bit but I wanted to know roughly how much would I need to on a 14 tooth piston? As I wanted to upgrade to a m110 spring. Obviously a high torque motor will be required also 😊
