Hi Teach! Cool idea! Can I throw out a suggestion for your Cub's safety, though?I see on most full scale planes have some sort of device to keep the skis at a desirable angle when in-flight. Check out this pic:

I think they have bungees on the front, and a rope or cable on the back. I think once airborne, the bungees pull the front of the ski up, the cable at the back controls how far up it will go. Without them, who knows where the wind will spin them? Of course, maybe on our little planes, the weight will be enough. Just a thought.
Good luck ! Looks like fun. The only skis I can try here are water skis!
