I just got back from flying my airplane. It is a GD monster acro machine. It's built to do airshows. I only flew for about 15 minutes and was ready to puke by the time I landed. Whew! What a monster.  |

Are you familiar with the Red Bull air racing series, and if you are, what do you think of the format compared to the head to head, around the pylons racing, like at Reno. I caught them on tv a couple of times, and they had a G meter up on the screen, if I remember right, and I think I do, they were pulling up to 12 Gs in some of the manuevers. 12 fucking Gs, that really raised my eyebrows. www.redbullairrace.com/ |

I thought Red Bull was pretty cool. When I was flying the F-16 I would come back and see 9 Gs on the G-meter and not even remember when I had done it. Today, by comparison, I had +5/-3 on the meter and thought I was going to puke. Your body develops G tolerance when you fly that radical shit all the time. I haven't been flying enough and my G tolerance absolutely fucking sucks right now. |

[
Have you ever been on a centrifuge, where they run up the Gs untill you zonk out? Don't AF pilots have to go through that every year or so, for familiarization, like the Army made us go through the fucking gas chamber every year?
I forget the exact specs, but I'm pretty sure that operating in the normal catagory, in my old 172, at +5 or -3, I wouldn't be pukeing, I'd be shitting, because somewhere around there the wings would be comming off!

Yeah, I did the centrifuge. I hated that fucker as bad as I hated going into the gas chamber (I did that too - with tear gas). They don't just zonk you in the centrifuge though. They do a programmed and briefed series of accelerations. You start off with the G-suit disconnected and to to five or six Gs as I recall. Then you stop and hook up the G suit and do the same thing. The G-suit I flew with only added about one G of extra tolerance. The new ones are awesome - they have some kind of forced oxygen system that I am unfamiliar with. Then, after we did about 6 Gs, they spun us up to 9 Gs and we maintained that for 30 seconds or so There were a few other accelerations as well. We had to do one where we were looking back over our shoulder. I did the centrifuge in Amsterdam. It had a shorter arm (shorter radius of circle traveled) than the ones stateside and it had the side affect of making us feel like we were tumbling as we slowed down. The acceleration and the spin were OK, it was just the slowing down that fucked us up. It was an unintended consequence of a bad design. It seriously sucked. |

As far as the "utility" category goes, I forgot the max Gs, but it's something like 2.5 as I recall.
My wings will withstand +/-20 Gs, but the engine mount is only stressed for +/-10.
The engine will break off the airframe WAY before the wings would break.
However, with my tolerance at no more than 5 (or maybe 6 on a good day), the airplane is WAY stronger than I am.
When I go out (on a good day) and fly the SHIT out of that thing I come back with +6/-4 on the G meter.

I've seen birds like yours performing on the airshow circuit. That's one hot little number you've got there Bob. Me, I'm what is technically known as a "white knuckle flier." When I was flying as cargo as a military courier it was bad enough flying in a C-141 after the reports of wings falling off the damned things, but the one I REALLY fucking hated was a little contractor puddlejumper we called "Teenie Weenie," a Mitsubishi MU-2 twin turboprop with room aboard for pilot, copilot, 2 couriers and about 75 cubic feet of cargo. Our pilot's I swear were gluttons for bad weather or getting down below the peaks around Knoxville and Ashville and flying slalom through the valleys. I never gave them the satisfaction of seeing me puke. I'll stay on the surface thankyouverymuch where the decks only heave and roll 45 degrees or so and I can walk on the bulkheads like any normal joe. Never been seasick, believe it or not. ;D |

I have flown the MU-2.
We call it the "rice rocket."
It's pretty fast and it's built by Mitsubuishi (get it, "rice - rocket?")
lol

Hey sailor, as far as "sea sick" goes, I get that really bad.
I am the worst.
I could puke while lying on a float in a swimming pool.
LOL, well, I'm not "quite" that bad, but I puke easily when on the water.

I am thinking about taking my daughter's video camera up with me and doing some acro.
It probably won't come out too well, but what the hell?
It's worth a try.

I thought they were a little more than that, so out of curiosity, and to refresh my memory I looked them up. As you know the airframe is actually tested to 150% of these load factors, so you might get away with the +5, but the -3 would be a killer. Happy Landings! C-172 MANEUVERS - NORMAL CATEGORY. Gross Weight..........................................................2200 lbs. Load Factor, Flaps Up..................................+ 3.8.....- 1.52 Load Factor, Flaps Down.............................+ 3.5 MANEUVERS - UTILITY CATEGORY. Maximum Design Weight.......................................1950 lbs. Load Factor, Flaps Up.............+ 4.4 ..... - 1.76 Load Factor, Flaps Down........+ 3.5 |

I was thinking about looking that up.
Thanks
It makes sense since a simple 60 degree angle of bank will get you 2 Gs.
