If you look close at the ski in the picture you can see the socet head screw that tightens up on the axle. This keeps the ski from rotating up too far by hitting on the ski. The spring loops over the top of the bolt to keep the ski pointed up a little during flight. I had to grind a flat spot in the axle to keep it from rotating and also the axle needs to be tight on the gear to keep the skis where they need to be.
