Q1: Do you need four seats?
If you have a family, or often travel with another couple, then the answer may well be yes. If so, there’s only one choice in the RV world – you’ll be looking at an RV-10.
If for the vast majority of your flying, two seats are sufficient, there would be little point in spending the extra money and time building the RV-10. Then your choice lies with: RV-4, RV-7/7A, RV-8/8A, RV-9/9A, RV-12 and RV-14/14A.
Q2: Do you want side-by-side or tandem seating?
There’s no doubt that sitting on the centerline is a cool as you can see out of both sides of the airplane. However, the tandem concept does not put both occupants on the same footing. The RV-4 and RV-8 are very much pilot-and-passenger airplanes. The person in back is the passenger. They have rudimentary controls, but they can’t see forward, don’t have access to anything on the instrument panel and sit with their legs straddling the pilot. Total baggage space is much the same as in the side-by-side airplanes, but it’s divided between two smaller compartments, so bigger items, like folding bikes or golf bags, won’t fit. The side-by-side RV-7, RV-9, RV-12 and RV-14/14A on the other hand, have large baggage bays spanning the fuselage and both occupants have the same forward view and access to the controls and panel. Consult your “other half.” You may find their views essential to making this decision.
Q3: Do you intend to fly aerobatics?
If you are really, truly interested in sport aerobatics and one of the reasons to have an airplane is to rotate freely in three dimensions, the RV-3, RV-4, RV-7/7A, RV-8/8A and RV-14/14A will fit the mission.
The RV-9/9A, RV-10 and RV-12 are not aerobatic airplanes
If you are not inclined toward aerobatics, but your mission statement does include economic long distance cross-country flying you can take advantage of the longer, high-aspect ratio wings on the RV-9/9A and RV-10. Although any RV is capable of long distance trips, these airplanes are particularly suited for the role. They are quite fast, even on moderate power. They operate happily at altitudes where true airspeeds are high and fuel consumption is low. The more “relaxed” handling qualities mean that even long legs can be hand flown without fatigue.
