Update
Still working on the drawings but making some progress figuring out how I want things to fit together. I think I about have the nacelles worked out. Wing is getting close also. Vertical and horizontal stabs just need final details added. Fuselage needs simplified some.
Tip floats are driving me crazy though. I know I will most likely just carve them out of solid foam in the end but really would like some representation in the CAD model.
Here is a picture as it currently sits with some dimensions on it. I am planning on powering it with a pair of 1804 or 1806 motors but I should be able to scale it larger from here if I decide it is to small.
