Wouldn't Richard's single rotor be a great motor for a LSA legal RV-4!

 

OK, here is the rule quoted from SportPilot.org:

Experimental amateur-built or =E2=80=9Chomebuilt=E2=80=9D= aircraft require that the major portion of the fabrication and assembly ta= sks be performed by persons who are building the aircraft for their own edu= cation and recreation. (This is commonly referred to as the "51% rule".) Th= ese aircraft can be flown under the SP/LSA regulations as long as they meet= the definition of a light-sport aircraft as called out in FAR Part 1.1.

 

I interprete this to mean th= at any Experimental that meets the LSA rules can be flown under the LSA pil= ot rules.

You can do a couple of thi= ngs to "limit" the top speed. Don't install wheel pants initially at least,= and pitch the prop correctly to the anticipated top speed. The only other = consideration I can think of is the gross weight. You might want to check o= ut all the regs pertaining to LSA's.
