Regarding the RV-9's that were certified as LSA's, I spoke to the builder when he was doing this to find out how he was doing this.
He comment was, "If found where to remove weight without compromising the structure."
I know my -9 was less than a 1,000 pounds for its first flight. To drop an additional 100 lbs could be done if he used ATO fuses in place of heavy circuit breakers, left off landing, taxi, position, and strobe lights. Only primed the few parts Van's says you must prime. Only install brakes on the left side, Install a Dynon D180 or something lighter. Replace all the fiberglass parts with carbon fiber, install the lightest components you could find (radio, transponder, intercom, etc.).
Leave off the gear leg & wheel fairings and install a climb prop to limit speed and you are there.
Regarding the engine, I believe he used O-235's, not O-320's, because he bought my O-290 baffles and some other parts when I switched engines.
Is it possible to build an RV-9 to fit the LSA requirements? I believe it is but I'm not sure I would want it.
