Looks cool! I have thought about doing this to my Chinn Yak. How does it affect the 3D maneuvers? Does it change much between floats on or off? I know most profile guys have a very rearward CG as well. How does this translate to float flying? It looked like theGee Bee in the video had a fairly conservative CG setting and flew mostly in a sport plane style. Do you have any 3D videos?
