Yes, I am sure they have a big following in Germany and the like. I read some time ago about the accuracy competitions they had. Hell, they would build these skydiver models which were very realistic and drop them from under the wings of RC aircraft. Next, they fly the parachutist in for accuracy landings. It looks fun. With that 21, I would build a dude that would wingload that rascal at about 1.8, then swoop ponds with it. THAT would be outstanding to see. Of course, chow once and you would probably fry the electrics.
