Just finished a Somethin' Extra with OS 46FX on a set of GP 40 floats to fly at our lake. I have a SE ARF that I fly at our club and decided to build one to put on floats. Only required a few slight modifications to the fuse to accept the floats. I can remove the floats and extra rudder with seven bolts and install original landing gear with three bolts for land flying (if necessary) in just a few minutes. Can't wait for maiden flight (I think).
