Here's some changes I made to the Villain S1:
1. I made the radio box removable from the hull.
2. I applied the sponson bottom piece as two pieces. The first 11" is applied first, then the remaining section. This really helps assure the back 11" of the sponson running surface is flat.
3. I hollowed out the sponson frames.
4. I applied outside edge running strakes to both outside sponson edges.
5. I'm running 3 oz. of lead in the nose.
6. The prop is a backcut 1440 with the edges slightly cupped.
7. The prop is 3/32" above the sponsons when the boat is placed on a flat board.
