I did some experimenting with a Medallion 09. Additional washers under the glow head will tame it down. I friend has an LA 10 on a Jr. Flite Streak. It flies pretty well on fairly short lines. Sorry, don't know exactly how long.
I'm thinkin' that it might fly better than you think! Didn't Wild Bill publish something like this in Flying Models a few years before he passed> It wasn't called BareCat. There were three sizes for different small engines. Part of his Doodlebug series? Some one help me out!! And go check out the video of my AWSOME Cox Stuka flight today over on the main forum! Type at you later, Dan McEntee
