got a set of 60 size Goldberg Superfloats off ebay,and relocated some Hobbico gear forward and used the wire ones supplied for the rear.
some cutting and rebuilding was required to mount the forward gear, but not too much.I used nylon LG bolts to atatch them to a mounting plate
I also went up in engine size with a OS 61fx for that get off the water power.
the floats are covered now, I will do the fuse this afternoon so I should have more pics.the floats were not to expensive but there a kit so you have to build them. tower sells some 60 size floats but I think there like 80$ mine were half that but there's the extra work of const. I also glassed mine before covering with Econocoat.
