Louis A. Stolp and George M. Adams designed and built a light sporting biplane known as the Starduster SA100, which flew for the first time in November 1957; and founded Stolp Starduster Corporation to market plans, components and basic materials to amateur constructors (Aircraft spruce now markets the plans). Later on they introduced the SA-300 Starduster Too, which was an enlarged two-seat version and is suitable for engines of 125-260 hp. The prototype SA-300 was powered by a Lycoming O-360-A1A flat-four engine of 180 hp.

After Lou sold the startduster company they designed Acroduster SA700 (1 seat) and SA750 (2 seats), an aircraft series designed to give the early Pitts a run for the money. The end result was an aircraft with much better behaviour then the pitts on the ground and in the air but not as acrobatic as the later. Given the choice I personally would go with the Acroduster anyday…

In the seventies the oilcrisis made an impact even in the homebuilt arena and Lou designed the SA500 Starlet and the SA900 V-star.
The are pretty much two designs of the same concept of single-seat, economical fun to fly, advanced sunday acrobatic designs. Most of the are powered by a Lycoming 235. Personally I would consider to give my vote on the V-star as the prettiest little homebuilt ever constructed.
Anyone interested in any of these designs I would keep a very close eye on the weight. Initially intended to have gross of 1000lbs I have seen V-stars that has an emptyweight way over that! Because of this the 35mph stall suddenly is subsancially higher and I would be very carefull not to stress the aircraft in any way by doing acrobatics in it. And suddenly the whole point of the aircraft is gone. No longer a nice handling, friendly arcrobatic aircraft it just turns into a static object. Just my 2c…
