RE: NitroModels .25 Cub
If you can keep it in that weight range it may work out... it certainly will be a floater as well.
Frankly I would have gone with a .15 or .25 equivalent, but this would have increased the weight and wing loading more towards the top end of the stated weight.
I have one of those motors and it looks a bit anemic for that size plane. I was going to put it into a small foamy...
