Ive been donated a Mcculloch 210 21cc engine ive been told it wouldnt pull a skin off a rice pudding lol.But ive got my engine man to polish and port it add an airram to the intake and add a 625mm long tuned exhaust, hoping that it would give it a bit of power.
My idea for it is a deep vee hull similar to a Fountain type with a few added extras as my radio is sophisticated type with many mixes and channels so i can add moveable tabs and other bits too.
Can you advise what sort of length , beam ,height would be good for this project
