There He Goes Again.........
So I started doing some sketches of how I would revise Jay's design for a lower-profile motor and an 850~1200mah battery.
Lo and behold, I came up with a low-profile design that uses 1" foam and the same motor/prop/shaft combination.
The plan view is essentially the same except I rounded the nose enough to make it just under 350mm. The profile view resembles a Frisbee with a flat stern. I think I will make 3 templates from 1/4" MDF (the upper hull, the lower hull, and the hatch) and use my table-mounted router to cut the foam to shape. That way, I can make as many as I want. The rest is simple, some 1/32" styrene sheet, and I'll cut some motor mount parts from 1/16" ply in the "extra" space on a sheet from my rigger project.
This arrangement will allow me to get the motor lower in the hull, reduce the driveshaft angle (it will exit at the top of the step), and greatly reduce the profile. It's going to look like a little flying saucer zipping around the pond. ![Spy](images/smilies/set2/spy.gif)

UPDATE: I have some 1" pink foam; I have some MDF to make templates; I have stuff to make a 1/32 wire drive; I have motor couplers; I have motor mounts. When I finish all the other projects, I'll start this one. The motor/coupler/receiver/ESC/propeller will all go into the new one.
I may leave the old hull/driveshaft/motor mount/servo/rudder intact for future experimentation, but it will definitely be relegated to the "Retired" pile.
