It's in tatters and doesn't have a zipper. I going to take a look at the one on the rear stick to see if it is the same size.
Check the base dimensions. Looks like only 5x5" (10" from corner to diagonal opposite corner). Too small for my RV-4. And you'll have to add a zipper depending on your stick grip.
Still, could be modified to work. Great idea.

It should be here tomorrow. I plan on using some velcro instead of a zipper.
