There are also ultralight helicopters. You're not going to find many of them out there and so trying to argue that compartmentalizing a site that already talks almost exclusively about LSAs or things germane to LSAs is probably going to be counterproductive. I appreciate the desire, but then again you're just not providing a very good reason for a separate sub-forum.Yes, there are light sport hot air balloons. The aircraft can only carry the pilot plus one passenger, and it cannot have a gross lift of more than 1,320lbs., which is much more than adequate for small hot-air balloons.
