I just found out that this plane was desgned for .40 size to .49 sized engine so i'm ok there.

I could go to 11 sized props but i would just make it, because the grass on my feild and how low the plane sits. I have already ordered the Evo prop driver. but why wouldn't they put a prop driver on the .45 to begin withm instead of the flywheel. Does it make a difference.

I should finnally be able to get it up tonight if the weather holds.
