Thanks for chiming in Ed. Power comes from an OS 61FX. It really hauls in the air and gets off the ground in less than 30ft. Do you recommend a specific brand of floats? Weight is about 6-7lbs all up. I have the covering stripped atm, so it is feasible to make the structural mods you mentioned behind the wing saddle. I was thinking the same thing since the lower wing is fairly easy to mount up. As for waterproofing, do you bag your Rx? or anything in the plane?
