RE: RCGF Engines
Nope... If you just take the stoke as is... Many people make this mistake.(can't tell you how many people i've come across, saying engine specs are wrongect becuase they can't domath).Power is only generated under compression... If you look at a two stroke the exhuast port is part of the stroke, so the actual power stroke is the stroke length minus the height of the exhuast port... Then there is alsothe gap at the top of the engine for the sparkplug.. Engine size is something like 15.8cc.. Remenber... Engine capacity isn't just bore*stroke!

@raydar I totally agree, It is 40c in rand terms, so that is about $ 0.05 per nut... Not all that expensive...
