FYI - We had a practice session at LKR on Saturday and Ron "Smokey" Schreck (RV-8) showed exactly how well this system works when doing aerobatics by beautifully flying the Sportsman sequence with no "cheats" associated with eliminating the brief negative G portions. The flights would have scored well at a contest. With fuel injection and his accumulator, fuel and oil pressure were maintained throughout. No need for a full inverted system for an RV to be competitive.
