This things going to be electric. I have no experience with the electrics but I figured why not go for it. So I bought three micro servos, brushless motor, esc and a couple of batterys. I just tried the motor earlier this evening and power is not going to be an issue! This also happens to be the first prop that bit me! Very minor scrape but instantly gained respect for the little motor. The prop is only held on by an o-ring but they can still do some damage.

I'm almost done building except for a few odds and ends but should be covering this weekend. So far I'm just under a pound without covering. After running the engine I felt the need to beef up the wing a little but I should still be under my projected 20oz. The fuse turned out to be real solid once I sheeted the bottom yet still very light. I'm looking forward to getting its feet wet and see how she floats. I'm going to be pissed if this thing doesn't come up on step but won't know for sure 'til I try. Once I get to that stage I might have to pick some brains.

Anybody have any idea how much weight would be packed on by coating the fuse in epoxy diluted with a bit of rubbing alcohol? An oz at the most maybe? I don't think light weight covering is going to be water tight but I could be wrong. And will the covering stick to epoxy? Might just have to paint it.

I'm also wondering about esc and battery temps. They'll both be in the fuse but there's little to no air circulation in there. I might have to ask the electric gurus that one. And if these do heat up, how do I waterproof them? Can't really wrap them in balloons then either.

I should be able to download some pics tomorrow.
