The previous post is correct. Spray rails and keep it light. The plane is basically a waterborne primary trainer. Flat-bottom airfoil and larger stab gives it remarkable slow speed capabilities. Mine has a Thunder Tiger Pro .36. It would fly fine on a glow .25. I didn't build in a hatch which means that I'll have to do surgery if the tank ever needs to be replaced. For my color scheme, I used white as a base color and orange panels for trim. Kinda like a Coast Guard scheme. Very easy to see.
