    You may have to rig them up a few more degrees. Mine was 1 deg up or so and I lengthened the rear cable 2 inches and they don’t drop down anymore

    I'd contact the current manufacturer and have a conversation about the in-air drop down. It might help them and others figure out an improved rigging setup and test flight after the installation. Sometimes that test after mod is required to determine compatibility but not sure with this STC.

    Newer bungee material sucks compared to what they used to make. I learned that if I left mine hooked up sitting in the hangar even over night they were very slow to return to their original rigged length. Get some heavy snow on the tip and it took ever longer. Add the 6" crust cutter and its even worse because bungee is then shorter. I started unhooking them at the end of the day 20 years ago. 2 years ago I finally switched to springs.

    Thinking about buying a set of the TrickAir 2500s for my Super Cub, and I’m curious how they perform? I’ve flown SkyWagons on penetration skis and some are okay and some were horrible.

    My 1500's are not as good as straight skis in the deep snow (understandably) and are poor in overflow conditions....it is very nice to land on a runway and up to the pump though....also it is nice going into and out of the hangar. there is a definite trade off in snow performance....I think the area behind the wheel causes most of the drag....Summit skis seem to have a more straight profile behind the wheel making them a little less draggy in the snow.

    My skis with springs would drop if you got over 110 mph. Lengthened the rear cable and solved that problem

    These skis look like they are rigged with the tips low in level flight, poor bungee didn't have a chance.

    That's what I thought as well. The lower connection for the bungee should also have a section of cable for a "crust cutter", to protect the bungee.

    Isn't the lower left side window/longeron one of the levels? If so and the right rear safety cable is tight then......not criticism just a maybe could be better.

    Best way to check that in the hangar is put a smart level on the window frame and lift the tail til the cables are tight.


    One place I read said 1-5 deg compared to the wings angle of incidence. I've always used fuselage level.

    I may be wrong but that probably won't stop me from arguing about it.

    I've also heard the 1-5 degree thing. When Aviat certificated skis on the Husky, they tried to get the FAA to approve 0 degrees, but the Denver ACO wouldn't approve, so they went with +1, and that worked great. I had the same experience with skis on that plane, when you descended, the skis would go over onto the forward limit cables. Was no big deal, just a bit of trim change. We took the bungees off and replaced with springs.....fixed.

    As Glenn noted, the new bungees are WAAAAY different than old bungees, and frankly not worth the $$.
