Floatplane?
#2
I fly a GWS E-Starter on GWS Floats. The E-starter and I think the GWS Beaver both have mounting slots for the GWS Floats, so there isn't any modification to do. You just have to assemble the plane and assemble the floats.

www.hobbycentralrc.com carries both, but I think their floats are out of stock. I got my floats from www.e-flightline.com
