Skis for my Champ

Hello again...

Looking at the 2+ feet of snow in my backyard got me thinking about flying UM planes off skis in my backyard. With its generous payload capacity and ample power, the Champ seemed to be the best candidate in my UM hangar.

After fixing some pre-shucked corn-on-the-cob, I found myself eying the packaging. Looked to be pretty strong, and the ends already had a nice radius that looked to be about right for the upward curve at the front of the skis. My first set ended up a bit heavier than I had planned. Although my gut told me that rear bungees would likely be required, I decided to try them with front bungees only.

Tried them out this morning (12/05/10). Temp was +10 F with a 2-5 MPH breeze. They worked pretty well - especially on hardpack or crusty snow. ROS takeoffs looked cool. When landing in deep fluff, she tended to nose-over on landing - unless I executed a power-on, full-stall 3-pointer. So, I rigged up some rear bungees. Heading out for a test-flight right now...

I'm also making a lighter set that uses foam for the uprights. This time, the rubber-band bungees will be incorporated into the ski design. Should weigh considerably less than my first set, and the install should be a bit cleaner.
