RE: LT-40 float conversion -- question about options
My LT-40 is on scratch-built balsa and ply floats, and it flies very nicely with a 0.46 turning an 11x6 APC prop. Very scale-floatplane like, but it can do a nice loop even so.
There are some pictures of it on my website: [link]http://www.mts.net/~mhultin/[/link]. Look in "My Hangar".
