Thanks Bill - that makes it easy for me! I'm also using the Zenoah. I had F/G'd these brackets to the inside of the cowl on my 1/4 scale Skybolt and it worked for a while. It was installed with a long shaft allen wrench (as Skinny Bob suggested), but the odd wack on the cowl eventually loosened them up. I re-epoxied them in a few times over the years, but finally a radio failure wrote fini to the Skybolt thus solving the problem!
When I get my cowl from our friend Brad, (shortly) I will take another look at it. I fear that using the plywood ring ala Great Planes would compromise some of my cooling. But I built the GP Super Stearman for a friend and it works well for him - and he also used a Zenoah 26. Thanks for the help
