I'm gonna try to fix Richard's chewed up mainfoil from Long Beach. It's the first time I've had a chance to take a look at a Mach2 mainfoil up close. I always assumed that they were much lower area than my Fastacraft mainfoil, but after looking at them next to each other, its closer than I thought.
Anonther thing that stood out was the small flap movement. My foil has a whole lot of flap range. See the pics:
I couldn't hold the flap down and take the picture with my other hand very well but here's my best attempt at showing the amount of flap the M2 foil has:
My best attempt at measuring the flap down from my best guess at the neutral point is about 11-12 degrees for the M2 and 18-19 degrees for the Fastacraft. The M2 flap is bigger than the Fastacraft, so maybe that's how you can get away with less range. I think I'm gonna try limiting my flap movement some and see how it works.
