Ferrous eagle - looks like I might get my electric Demon flying sometime this century, I seem to have picked it up out of mothballs and I have finally found a motor mount I think will work well with the mounting plates in the Maxx 28mm clamp style mounts. I have 4 sets on order to bolt to try out in this and that, e.g. I seriously need to electrify the 26" Demon. Easier with outrunners I guess, but I like the skinny little 28mm motor can and you can get a fair amount of hp in that diameter.
I am using a 28 mm inrunner on my full size Demon similar to the one I used on the stingray. Running it with a 5.25X6.25 on a four cell I hope that I should be able to get it to at least the 200 mph mark, and as you know that is a pretty clean airframe with wings that are only 3/8" at the thickest..
