The warbird is owned by Diego Lopez, I think it's a Skyraider, something like 17 servos, everything works just like a real one..He and Gene Barton had 10 of the engines at one time..There was a twin made by Gene, don't know what ever happened to it..The crank is a Husky too, the case was made for airplanes..They really screwed up when they quit making them..I have one for myself.....
