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.

Here's my short maiden flight. 10-17 MPH winds, and temps in the teens. Camcorder was messed up at first - I inadvertently left it in manual mode from shooting some nature clips in low light. When my friend started filming, it oversaturated. So, I had to cut out about 2-3 minutes of good aerobatics, and some close-in flying. Nearly lost feeling in all of my fingers by the time I landed. Hope to get more video sometime soon. Need a set of skis, I think...

Here's one of me hiting a tree on final with my 1/4-scale Super Cub. I was just flying along, shooting scale touch-and-gos, when this tree got in the way. It's the only tree near the runway, and I managed to hit it.

I figured the wing would be mush, but the only signs of the encounter were a small hole in the fabric and a chipped blade. The Dynaflite Super Cub is one tough bird!
