Those were mainly the older, small tail AA-1 and original AA-5 Traveller. The Tiger and Cheetah are far more benign.
You’ve spun a Tiger?

No, I follow the rules. That is, however, the reason the increased the size of the tail.You’ve spun a Tiger?
I just don't get motion sick.
First tailwheel flight and landing(s)
First Cessna 140 flight
and soon to find out it's my first aerobatics flight.
Ha ha.. I asked the same thing.The 140 is aerobatic?!?
The airplane is not designed for purely acrobatic flight.The 140 is aerobatic?!?
One botched a hammerhead and spun in with a 17 year old kid in the back seat. The third had a structural failure at low altitude while racing at Reno.
You are really mischaracterizing these two tragedies.
(Necro thread, but what the hay.) Six g's? If those maneuvers were done right then that was a heck of an "arrival".Aileron rolls, snap rolls, loops, Cuban 8's etc. The analog g meter peaked at 6 g's.

Yesterday I went up with my instructor in his Citabria. We did some tones of aerobatics most of which I was flying with him assisting. I expected some brown moments, I was super excited and not once felt scared, and even times wanted to push the plane even hard.
Anyone else have a similar experience?
I have never flown a Pitts, but I met Curtis back in the '70's at his farm in Florida. As I remember he wasn't thrilled with the new symmetrical wing design, at least as far as newbies were concerned. I guess he thought it was easier for amateurs to over-stress?There is nothing wrong with pulling 6Gs in a Pitts.
Don't know what "warbird" acro is, I never flew a warbird either that I can remember. I had a PT-22 parked in my back yard when I was a little kid, if that counts. The wings were rotted out, but it was better than a swing set for me. I've done my aerobatics in 7ECAs for the most part. I've had two over the years. I LIKE big round loops with about 3 'g's at the bottom, zero at the top and half the speed as at entry. I envy being able to fly maneuvers without having to work so hard at it. The stick forces in my Citabria took some of the fun out of it, I think. I still had a blast, though.If your experience and interest is limited to lazy and simple "warbird" acro sure....
Exactly. This was a first-time experience, so I assumed the flight was conducted accordingly. Maybe the 6 'g's came from the "etc." maneuvers unlisted and not a hard landing?...you don't need near 6G...

Not true at all. I used to position observers perpendicular to the plane of my loops and draw them as they saw them while I numbered them and recorded my impressions from the cockpit. This was before video cameras. The roundest looking ones were as I described. At first, though, I would do them oriented to the runway alignment and not 90° to the observers. Took awhile to realize the slight difference in perspective was causing the loops to look like hairpins when they "felt" (and were) nice and round.... be aware that flying 3G loops in a 7ECA results in a shape that is nowhere near round.

I don't claim to know it all and I did bring my own judges and I also did my own math. Floated across the top at about half the indicated airspeed as entry and always got rave reviews on roundness. YMMV.Sorry but you're flat wrong.

Quite possible. So I just looked in William Kershner's Advanced Flight Instructor's Manual, 2nd edition. There he has a force vector diagram under similar conditions to what I recall, half the airspeed on top. Assuming 1 g at the top, the g force at the bottom is 4 times as much, or 4 'g's. So if you fly over the top with zero 'g's aren't you only going to need 3 at the bottom? It's a bigger loop. Not as intense. That logic comports with what I recall as being a 3 'g' differential based on my own calculations of turn radius. But you're right, it's been eons since I did these or thought much about the theory. I do remember being slightly higher than 3 'g's at the end of the maneuver, say 3.2g. Kershner says something about that, too, but I didn't read it all.Well clearly it's been a while for you and there are things you're not remembering correctly.

Well the thing is that most pilots who fly any sort of acro don't care about flying loops that are exactly round, nor would they even have any idea how close they got to it unless they have had a significant amount of ground coaching and practice with someone knowledgeable on the ground with a radio telling them in real time how to adjust their inputs to make it actually round. This is not a figure that's easy to self-critique. General aerobatic advice that floats around out there in books or otherwise is not necessarily specific to competition aerobatic standards of precision, since it just doesn't matter to most. 99% of pilots who do loops do egg-shaped loops and they are actually more enjoyable for recreational pilots since they're low G, carb engines don't sputter on top, and dust and dirt on the floor of the airplane doesn't fly up and float around during the zero G float on top. I don't know of any airplanes that will do an actual round loop while pulling 1G on top, but it works for recreational loops. The reality is that almost all aerobatic airplanes need significantly more than a 3G initial pull to do an actual round loop. It's 4.5-5G in most, whether it's a Pitts or a Citabria. No need to analyze L/D ratios and force vectors and such.
Warbird acro just means the easy lazy low G positive G basic stuff like loops, barrel rolls, and Cubans.
The usual term is "gentleman's aerobatics". What I do in my Hatz. I don't care if my loops are round, nobody's judging. Though in one video I have of me doing a loop taken from another plane, it looks pretty good and round, probably visually stretched by the relative motion.
There was a CFI who thought it was cool to demonstrate a hammerhead stall during my C172 checkout at a new-to-me airport. I was too much of a newbie to be scared or even to know that it was improper. Does that count?
Definitely not a lazy eight. Pretty sure hammerhead (that's what he said it was) but then again, it was almost 32 years ago and I had all of 68 hours experience.Are you sure it was an actual hammerhead, and not a wingover or lazy eight?
Same here. I could eat what would be considered the worst pre-flight meal ever and it wouldn't phase me no matter what the plane was doing.
On the other hand, my wife gets motion sick at the slightest bounce.
What is the real difference between the hammerhead and the wingover, providing you don’t tail-slide it.Are you sure it was an actual hammerhead, and not a wingover or lazy eight?
