Default RE: Heinkel 31 Float Plane

Now that the Heinkel is debugged and named ("Seedrache") I'm going to start on a Herr Aqua Star.

I just got done looking at all the posts on that one, and have a few thoughts:

1. The plans show the CG right over the step on the hull. Everything I've experienced to date with ROW says this is trouble. It causes difficulty getting on plane, and more difficulty in rotating for takeoff. I'm going to relocate the step former 1/4" forward.

2. It's a deep V hull. I'm a power boater, have been for 20+ years. I have a 26' foot Wellcraft cruiser, and it has a deep V hull. It takes a LOT of power to get it up on plane, and without trim tabs to hold the bow down, it won't stay on plane at a comfortable cruising speed. The floats on the little Heinkel have nice, FLAT bottoms, and even when it was underpowered, it jumped right up on plane. I'm going to modify the Aqua Star so that the hull has a flat bottom. Shouldn't be that difficult.

3. I will add the chine rails as suggested in the mod sheet, and start out with the engine at 0 degrees thrust.
