I haven't heard much about a 61 FS on this plane, but from what I've heard, a .46 2 stroke is perfect with the LT-40 on floats.
Anyway, anybody know much about Hobby-Lobby floats?

There's some info on the expensive fiberglass floats that H-L sells, but i'm talking about the $50 ABS plastic ones at the top of the page. 34 1/4", 11 oz each without hardware, rudder setup included... sounds good, no? Any experiences on it?
