You can PM me if you like. I build and sell both ultralights and experimental aircraft. The rules aren't as bad as most people think and there is no requirement for inspections of work areas, only the finished product. I've been through the process several times and it is easy to do with an EAA DAR.
As far as ultralights are concerned, they are hardly lawnmower engines strapped to kites. I fly a Flightstar with a 60 HP HKS high performance Japanese four stroke racing engine, the same BRS Parachute that is on the Cirrus, GPS, Radios, Intercom, cabin heat, full instrumentation, state of the air composite construction, and I burn only two gallons of car gas per hour with a 5 hour endurance at 85 miles per hour. Best of all, it's N numbered and all flight time counts toward any FAA rating. Not bad for an operating and maintenance cost of less than $15.00 per hour!
It can keep up with the Champ and Cub with no problem at all and it's LOTS of fun to fly.
