Like Villa said, the skis should work fine. The long set screw on the outer collar should be pointing towards the front of the plane, and down about 30 degrees. With no weight on the skis, they should tilt up about 10 degrees. Once you put the spring on, you can just adjust the long screw until you get a good angle.

The Maiden Skis look beautiful, and I would get them if I did a lot of snow flying, but I've used the Dubro's for two years now and they work fine.
