A Cub probably floats more than a trainer. My brother's Goldberg Cub with a .61 wouldn't land at all with a 'stock' prop for a .61. I think it was a 11x6 or 12x6. He flattened the prop - either a 12x5 or 13x5 and it slowed the plane down enough to land.

Yep - a Cub with an idling engine slipping to the runway is a thing of beauty.......
