I have the 40 goldburg cup on the goldberg floats with a saito 56, and shes a bute! flys very scale like. i ditched they're water rudder rigging and made dual rudders with pull pull cables more like a real float plane, and the wires that came in the kit needed some slight adjusting to get the floats flat, and they aren't scale at all. but ive had great sucess with they're floats, and they look great too. only thing i would add is a steel wire or something in the keel at the step to toughen the area that sits on the ground a little bit. i also painted the floats with polyesther resin and then aluminum paint. also make sure the blind nuts in the floats are held in really well, it sucks if they fall out.
