The main difference is strength, the RV7 is stressed for aerobatics, the 9 is not. Additionally the RV7 tailplane has a swept leading edge (it is common to the RV6, RV7, RV8)while the RV9 has a straight leading edge. Elevators are physically interchangeable between 6,7,8,9, however those with 0.016 skins are only applicable to the RV6. RV7, RV8 require 0.020 skins to control flutter against the higher Vne of those aircraft. Dunno about RV9 elevator skins. The RV7 should preferably fly with the wide chord rudder that is unique to the RV7. The narrow chord rudder with 0.020 skins is commont to 7, 8 and RV6 with the tall fin. Dont mix and match without discussions with Vans. There are strength, balance, flutter and spin recovery implications in designing tails.
