A few days ago I read a post by someone (can't find it now) that suggested to get rid of the "wasted" prop that comes with this plane and buy a 5X5 carbon fibre prop. I was told by my LHS they did not carry them but they had a composite prop. So I got it and the adapter and it does not even push the plane on the ground!

Anybody have advice on a replacement prop for this plane that is markedly better than the original?
