Hi Dave - glad you made it back from the US of A - think that 7mm is the way to go for punchy guns - would hate to measure the deflection on the 6mm 115cm spear in teh 80cm teak gun ! But I guess it is a bit lighter and the 16mm rubbers or whatever they are work ok.

You can get different results with the band stretch too...

THis is the formular (I know that you have less control over this but might be a future test ?) :

(Stretch length x 2) / 3 to 3.5 = length of rubber

Put 3 for long rubber or 3.5 for bomber setups...

(Centre of hole to back notch - not sure if this is to the end of the rubber or to the end of the 4cm wishbone ? Anyone got clues ?)

(79x2)/3= 52.7 longest setup
(79x2)/3.5 = 45.1 shortest setup

More testing Dave ! Catch you soon - Ed
