This fella used to be (or maybe still is) on the Allison owners forum years ago and had a really neat XB21 that someone referred to as "big bird". He sold it and then I hadn't heard or seen him post.
I was cruisin on S&F recently and came across a guy selling these prop covers and it turned out to be him. I bought 2 covers and I'll tell ya what.. the absolute nicest piece of work I've seen someone stitch together. I really hate to put one on my prop to trailer but he says that what they were designed for. I'm going to buy a grommet kit and install one on either side then attach a tether just in case it might blow off. Tim said he hasn't had one blow off yet but I ain't taking any chances.
Check them out!! I'll take a pic of mine and see if I can post them. Really sweet looking
