Hello Ken,
I don't know the name of either of your gliders, but the picture of the one that is not covered is both mind blowing and very inspiring to a relative newbie to this great hobby like myself. The craftsmanship and construction techniques look outstanding.!!!!

The plane appears to have at least a thousand pieces of wood in it and so beautiful just like it is, I would never cover it, no less fly it...
Thanks for taking your time for sharing your story and your planes with us. Good luck with your new trainer. I sincerely hope you and your grandkids thoroughly enjoy building and flying it. Please keep us posted.
David
