AHHHHHHHHHHHHHHH! I tried on the new Graupner prop I got (12.5 x 5) and guess what? Its too big! I decided to slip some fuel tubing over the crank but not im thinking no thats a stupid solution because the fuel tubing will definately allow movement.

So thast £4.75 down the plug hole! Anyone want a Graupner prop? Pm me.

Ok so now Ill try the OTHER plan which is try a 12 x 6...APC
