The small size and configuration really is challenging. the most frustrating thing is the plane is flipping over very easy, spending the time to dry out everything and risking the ESC/Motor getting smoked is really getting old, So far I've been lucky and it all still working.

Issues:

1- I think I should have made the step of the float a little larger,, it's really not breaking plane when it's moving plenty fast over the water. I may try to modify the step area

2- I need to stiffen up the outrigger floats, I think the light wire is bending back too easy and not supporting the wing tip very well, it seams when pressure is applied while turning sharp or on heavy deceleration the tip digs in and the plane flips over way to easy. My fear is the foam tip floats aren't quite buoyant enough also,, I may have to built up a set from Balsa/Monocote, but I'll try and support the wire with Monofilament first

3- High CG, the battery location on the plane make the balance point very high relative to the floats,, this obviously multiplies the issues with the tendency to flip over,, Not much I can do about that other than be super careful.

Here is a typical video of it flipping over,, at least my Son got a kick out of it
