We did so about 5 years ago (by land) and it was great. Highly recommended.
The key to their success was not the power but the control. The pilot steered by moving his hips - which moved the rudder. The key was that it also warped the wings and kept the plane stable. They discovered this first with their kites and gliders, then once they had the solution, those were abandoned. They went back to Ohio to build the powered unit. The presentation from the docents didn't make this clear during our visit.
Check out the cooling system for the engine - none. The reason for the short flight was to keep the exhaust valves from melting. The engine is probably as interesting as the plane.
We even went back a second day - no extra charge.
