I am preparing to construct an air boat to use on water/snow/etc. I
have twin 550 Titan motors and an EVX esc from an E-Maxx truck. I plan
to use both motors on the boat as a pusher model with above water
rudders. The length of the boat will be 28" with a beam of 14". I am
thinking since I am new to construction of boats, it will be made out
of 2" rigid insulation foam with some kind of a panelling decking. This
will allow me to "trial and error" somewhat cheaply until I really find
out what will work with these motors. I've done a fair amount of
research into this, but never could find a good source to what
propellers to use. Can anyone shed some light on the props I should use
or any other pointers I may need? My LHS is over two hours away and I
won't be there for another couple weeks. I'd like to have an idea of
what I need before I can get there.

Thanks a ton!
