Guys:
Keep in mind the projected weight of the Seawind is 10.25 to 12.25 lbs. Lets assume 100 w/lb for a sea plane to get off the water comfortably. Lets do the math. That becomes 1025 to 1225 WATTS! 1.025 to 1.225 kilowatts.

An axi 413016 on lipos can run at 1.0 to 1.2 kilowatts if propped properly. If you use 8s then you get the speed for a smaller diameter prop as required by the Seawind. or maybe.....wait a minute!

A blinding flash of Aeroengineering insight:

A four bladed prop!!!!! But made up of two regular two blade eprops. Has anyone ever tried stacking two props to make a four blader? It would need to be pinned or CAed or lock washered to keep a 90 deg. spacing. But it might work real good. You would need a custom prop adaptor to accommodate the double thickness of two prop hubs. And balancing should not be a major problem.

HEY, I might have something here. How cool would that look with two prop disks. Maybe paint the prop tips different colors. Selection of pitch at the required diameter, times two props will directly effect the torque requirement and so the current draw. WOW I think this may really be promising.

Thinking outside of the box is really fun. Come on you experts, what do you think?
