While they look cool, those giant props on out outrunner motors will probably be less efficient than a real prop in every way.
I'm sure they will be. They work by re-directing the backward, and the reaction of it as apposed the the pressure difference. i might try a rubber band power type prop as well. I still need to get this assembled.

The Limerick was perfect. Well done.

Last night I added a top to the canoe. and made the forward wing mount.

Here are some build progress pictures.
The wings have been made to be removable.

Ready for a toss. Wind is supposed to get nutty, so I may wait. If I can't try it, I will add some color instead. Any ideas?

Looks like clear dope linen to me, so a tan color.

Glide Test check for CG.
I made a raw toss, and saw was too far back @ the mid pontoon. Then I balanced per above, and started at the spar of the middle wing.
