Hi Roger, Its me Richard from the Stetsons club. Just received my ZDZ 80 a few days ago and I also ordered a beila prop with it. Its going on my new Ultimate. Its a 26-10 also but I have not tried it yet or the engine for that matter. Nice looking prop with lots of blade, and the craftsmanship is excellent. Sure looks good on my Ultimate. Someone on a post here mentioned that they seen one blowup in flight, I believe it was a 30-10 in size. But I have also read here that they pull hard and some people seem happy with them. Sure like mine!!! See Ya.
