Okay, I promised some pix of skiis for planes. The pix include: 1) two 13" x 3" white skiis [on the UCD 60, heaviest plane I have], made from a plastic bucket side, then straightened and bent again using a butane torch; the pic includes a Dubro ski and another I made from some special PVC we got last year, gray; 2) skiis, cut from the blue TOP of a drywall goop bucket. This bird is light so didn't require much length or breadth to support the plane; 3) two of the PVC skiis, one not yet put on the front wheel of a tricycle Dart. I used it for the Big Stik, too.

The skiis are attached to the gear with a simple aluminum angle iron available at most hardware stores. The angle irons are secured with rivets. The rivet gun and rivets are reasonably cheap, too. Drill a hole through the aluminum and PVC to match the rivet diameter, install the rivet and squeeze. Easy--and MUCH cheaper than the Dubro equivalents.

Nice thing about the Dubros are the springs which keep the nose of the ski up in flight. WE use rubber bands--standard. You can see where I drilled holes to accept a small dia wire, then put the band through it, voila.

THIS year, though, I've attached skiis on the Twist and UCD 60 with toothed washers so they won't move at ALL. I'm thinking that will work fine. The alternative is always trying to get them to look right, symetrical angles, in flight. And you only need a very little "up" in the tip so the ski doesn't dig in and upsot the plane.

Deciding on the width and breadth is a function of the type of snow you fly on, obviously, but the samples in the picture serve me in all conditions of snow, though in DEEP new snow you tend to throw it around with the prop. Fun!
