Flip, roll, tumble, loop, whatever while pulling less than +4.4 and it'll do fine. If you want to do aerobatics then build an RV of any number less than a 9. I once rode in a Pitts S-2B with a very competent pilot and we did ALL kinds of wild stuff while only pulling about 5 g's. More than one RV9 has done a loop. Kevin Shannon did when he built his and a picture in the vansairforce website shows that Cameron K (forget the full last name) must have in his too. The RV-9 has thinner wing skins and longer wings, those are two of the obvious reasons that it would not handle as much. +4.4 is better rated than your average Cessna, Piper, etc. Most are normal category at +3.8. If you have never been exposed to real g's, 4.4 is getting pretty serious. In the Pitts we barely made it to 5 and only once, and that was enough to get me feeling not so good.

An aerobatic aiplane supports G forces up to 9s like an EXTRA-300. A normal or utility category is about 3,8 and an -9 is 4,4. To make a good looping maneuver we must imput something around 3 Gs in an airplane. Could imagine what will happen if the turbulence add more 3 Gs in a -9A during the end of a looping maneuver? Go to -7 in order to do aerobatics. The -9 is a wonderfull travelling machine.

I don't have any plans on that, I still need to learn to take off and land :) so I won't be doing my 1st flight, wish I could but its not going to happen, I have not heard of anyone doing a roll before in a 9 or 9a, and I asked once about that just for the sake of discussion and got beat up pretty good so I never asked again.. so for the record, I am firewall forward on my 9a project, (finnishing up building the 0320 engine with a 30 year a&p help) If I wanted to do inverted spins I would have built something else, I just didn't know what created 2g's or 3g's infact I have never hung around and airport or have no friends that fly so I have alot to learn! but i do know the 9a is what I wanted to build and that holds true today as well.. do not archive Danny.. ----- Original Message ----- From: Subject: RV9-List: Aerobatic, to be or not to be > --> RV9-List message posted by: jc@infonet.com.br > > Hi there: > Just to remember, the turbulence create great G forces in an airplane. > An aerobatic aiplane supports G forces up to 9s like an EXTRA-300. > A normal or utility category is about 3,8 and an -9 is 4,4. > To make a good looping maneuver we must imput something around 3 Gs in an > airplane. > Could imagine what will happen if the turbulence add more 3 Gs in a -9A > during the end > of a looping maneuver? > Go to -7 in order to do aerobatics. > > The -9 is a wonderfull travelling machine. > > JC - Aracaju - Brasil > -9A > flying/travelling > PU-JCI > > > ________________________________ Message 4 _____________________________________ Time: 05:19:13 AM PST US From: jc@INFONET.COM.BR Subject: RV9-List: C&S speed X fixed pitch prop --> RV9-List message posted by: jc@infonet.com.br Danny: My -9 is flying with a beatifull fixed pitch three blade CATTO prop. But at 10.000 to 12.000 feet (due to high clouds) I felt the necessity of a variable pitch prop. At the time I was working in a firewall forward Ive never think about to spend some more US$ and install a governor, cables and all of the stuff to upgrade to a C&S prop. May be its your time now to think about it. Isnt it?

I need attainable short term goals (getting over a divorce) with a future of moving up.. If I had everything top notch now then what would I have to look forward too. ? ps: are you selling the Catto ? I like those too..

Seriously, you can't make the RV-9(a) aerobatic. When I'm letting down into KYUM and airspeed is near the yellow arc, I always find a few bumps and at that moment, an image of the wing spar/center spar attachment pops into my head. I always pull off a little power at that point. This plane flies well, lands great and - at even at today's gas prices - is fairly cheap to fly. Albert Gardner RV-9A N872RV 580 hrs, 21 states, Baja, and Oshkosh twice. Yuma, AZ Howdy, New to the list. Secondly, I understand that the -9 is not fully aerobatically rated. My assumption is the longer wingspan. Is there anything else? Is there anything a person could reasonably do during the building process to bring it up to aerobatic standards?
