I hope you do really really good barrel rolls. Cause when I do em in my +6G 8, particularly to the right, I sometimes end up going pretty much straight down. And if you do that, you may pull more than the 4.4 G's a 9 is stressed for.

(Yeah, I know--my barrel rolls are lousy):rolleyes:

I will remind you as I did several times in the past. The guy in NJ that pulled a RV7 apart was trying to teach himself aerobatics.
The OP is in socal. Lots of really good aerobatic training available in the area.

So what do you call a roll that was previously described as a corkscrew roll?

i.e. what your wingman does if your doing a perfect aileron roll (roll about your longitude axis)

Just to add a visual, this is what most people would define as a barrel roll, not sure what the IAC consider a barrel roll. it is supposed to be a ~1G maneuver.

Aileron rolls all day in a 9A with no more than 1.5G's recorded. Very nimble and smooth. Youtube can teach you anything.....

I almost hate to weigh in on this since there are so many different opinions. I was taught in several different aircraft that a barrel roll is a 2 G maneuver. I was also taught that you start the nose up and roll at a rate that allows the aircraft to arrive at the inverted position with the nose on the horizon and 90 degrees of heading change. Done right you roll out back on the horizon on the original heading and altitude. There is no way to do a barrel roll as a 1G maneuver. Common mistakes I see are not getting 90 degrees of heading change at the inverted point and as someone else mentioned winding up very nose down. Many attempts that I see are more a loaded up aileron roll than a true barrel roll.

Thanks for the good discussion everyone (but too bad it is now buried here in the RV-9 forum).
I now know that my (what I thought were) barrel rolls, are actually Hoover rolls.
I guess I should take on the challenge of learning to do actual barrel rolls.
