I had been meaning to convert mine to a taildragger for a while now and after a recent snow had a real desire to do some ski plane flying. I covered 2 birds at the same time. Converted to tail dragger and ski plane. The mods took about 3 hours and minor thinking to accomplish. I added a re-enforcement plate of 3/16 lite ply with triangle stock to the fuse directly behind the former that forms the rear of the tank compartment and used the gear from an old trainer. I added a 3/32 lite ply plate to the bottom of the fuse in the rear of the plane and attached the rear ski there. It is controlled by a standard servo, Futaba 3004. Piece of cake and flies well and ground handling is probably better then it was with the nose wheel. When the snow is gone I will just replace the skis with wheels.
