Building is pretty simple. Not much too it. Flying is the same as an airplane as far as the controls are concerned. Throttle, elev. ail and rud. Orientation is the hard part. With no wing to look at, sometimes it can be hard to tell which way it's going. That's the biggie. You can fly it from dead calm to fairly stiff winds but 5 - 10 mph seems to be the sweet spot.
