Our club is looking into buying an RV6A or 7A (built) and I have a question regarding engines and aerobatics. I did about 20 hours of aerobatics on a C152A a few years ago. I can't not see doing the same on the RV once properly transitioned. The usual loops, rolls, 1/2 Cubans etc. Anytime you took the 152 inverted a few times the engine would burp a small amount of oil, nothing unusual but it would always require a cleanup after the flight. I guess if we have a choice is there anything special regarding the engine that we should be looking for that would avoid this from happening? Thanks.
