Carl's statement, "just be very cognizant of Vne" raised my eyebrows a bit. I looked for Vne numbers for the 7A and the 9A in Van's website, but could not find them. Does anyone have the Vne numbers on the 7A and 9A.

Last year, I pondered the same Q's. Both have the same fuselage, but empennage and especially the wings are different. That being said... RV-9 pros - Perhaps a little more stable IFR platform. Better glide ratio. Lands at lower trainer like speeds. Personally, I like the aesthetics of the longer wing. Largest engine (O-320/150-160hp) is ubiquitous on the used (and new) market. RV-7 pros - Aerobatics of the "gentleman" type. This was my biggest hurdle - do I potentially want to do some down the road?? I decided not, but you always have the potential with the -7 (though I know folks who have admitted doing rolls and even loops in the -9, but great care is needed to avoid overloading the frame as with any utility category craft). A little faster with a bigger engine, but also a little more fuel burn for that increased speed (research I've done shows a slightly throttled back RV-7/O-360/180hp flying the same speed as an RV-9/O-320/160hp will have almost the exact fuel burn. This was also corroborated by a Van's engineer to me. Dan Checkoway's wonderful machine excepted : ) ). Bigger engine choices - though not really a big deal. Quite a few RV-9's with O-360's - just be very cognizant of Vne. Possible resale advantage with the RV-7 due to higher popularity and aerobatic capability. I chose the -9 for a cross-country platform and lack of interest in aerobatics, and frankly I like its looks more with the higher stance on the tri-gear and longer wing. Really try and get a ride in each, and play with some aerobatics in the -7. If there is a chance you want to yank and bank, your decision is made (though a demo ride in a -9 showed it could be jerked around just fine short of defined aerobatics). As an IFR platform, a good autopilot will help for the small decrease in stability - many folks have used their -7's IFR/Xcountry successfully.
