I don't know, hence why I ask questions.
I have had several competition aerobatic people tell me the RV4 was too fast to score well. I approached all of them with my list of planes
itts, Clipped wing cub, Citabria, Rans S-10, and an RV4
One won Sportsman in his Pitts and also has an RV6. He said Get the Pitts you will learn to fly it, skip the Cub, you will get tired of the Citabria, he knew nothing about the Rans, and the RV is great, but too fast for competition.
Another person is the guy that runs the club where I live. . His answers were basically: Pitts - You will kill yourself, Clipped Cub - Not enough power and a dog, Citabria - A good starting point, S-10 - 2 Stroke motors and long down lines lean out the mixture and risk a seizure, RV4 too fast.
The rest I asked fell into those same lines.... Get the Pitts and learn to fly it or get the Citabria and fly it for two years/150 hours. Not one person I asked said to use the RV for competition till now.
I also did some research and found that not a single RV was at the IAC nationals in 2008, 2009, 2010, 2011, or 2012.
So all the data I have gotten so far has told me that an RV is not good at competition acro. I am more than willing to look at other data... Do you happen to have scores from IAC competitions where an RV placed?
