Each ski has a pair of fins, stuck to the sides, with a tailplane across the top.
The ski is free to rotate about the axle and the tailplane stabilises the ski so that it flies in a level, low-drag, attitude.
It works much better than the array of springs, cords and wires that I tried at first.
This time I made the top of the ski flat for ease of building upside down, and the curl up on the ski front seems to be enough even on this powdery snow. The ones I made a few years ago (the black ones) had more curl that made building more awkward and didn't seem to ride the snow any better.
I was looking at this post and thought it was interesting, but never expected to ever fly off snow again, we just don't see it that often. After a week of 50 and 60 degree great winter flying weather we just had 4" ofsnowthe other day, so maybe I need to work on some ski's.
I had a set when I was in Michigan andhad a lot of problem with the springs, etc. like you mentioned.
I like the idea of the T-Tailthat youhave on yoursto replace all that junk. Great idea!
