RE: U-CAN-DO on floats?
Not only doable but would be a fantastic combo. I've had 4 UCANDO .46 (Saito.91) love it, them, just do stupid things too close to the ground with them. I have a Dazzler on floats, this would be many times better... Make sure you seal as many openings as possible and use a heavy grease around the servo shafts or water tight servos..
Oh, and have fun!!!!
