I haven't (seen photos) but I've read enough NTSB gyro accidents, and "aftermath" photos from the British AAIB, that my mind's eye fills in. Ya know what I mean. RAF says that it "stabilizes the rotor." It's still pretty experimental, I think. They had it on a gyro in the tent at OSH and I could not get a coherent explanation. Everyone said talk to Duane. However, at Fond du Lac Duane was busy as hell doing demo flights. I spent one half day there -- all I could -- and never got the chance to talk to him. His gyro had the rotor stabilator on it. As Dofin explained it, it serves to both return the rotor to its position/trimmed speed, and also -- and this, in my opinion, is the more important use -- to provide asymptotically increasing stick force with stick displacement. In other words, the more you move it, the more it resists being moved. This might be very beneficial for a novice RAF driver -- as you well know, and as I am slowly learning, it's a fingertip airplane, not something where you throw the stick around with wild abandon. But even Dofin said, "talk to Duane," so until I do, I can't say with 100% certainty what his goals with the stabbed machine are. He clearly is pretty confident with it because he flies pax in it on demo flights, but then again he's got a bunch of gyro hours. The gyro forum is down right now. Where can I find that?

There were four left, but the one in Florida got all his tickets suspended for a year. I have flown with that guy and while he enjoys the capabilities of the RAF, I didn't think we were ever within hailing distance of "unsafe."

Hey Bill, In my opinion this is a motocross term; WTFO: Wide Throttle, Full Open. It is not used in aviation. By the way 4,000 hours in GA is probably equiv to 10,000 hours in airline hours since most of that is on autopilot reading magazines. I agree. Down low, dirty and slow, riding in the wx and the bumps is where I spent that 4000 hours. I have 2000 more in the front seat of Huey's on floats flying in **** wx. It was all real time. 10,000 in the Boeings on autopilot above 10 thousand msl talking about pussy and real estate deals is not the same. But, there are some good guys out there with a lot of experience who did that too. I have a buddy I just had lunch with who just retired from Continental with 35,000 hours. He flew P-3's and the Constellation before that in the Air Farce. He's got some stories...like flying through typhoons. But, he also built a Pitts S-1 and competes with it too, so he really can fly.

5 WORDS..... Horizontal Stabilizers ARE ABSOLUTELY necessary.... No amount of pilot skill will prevent a push/roll/bunt over event if the gyrocopter experiences a zero g event.......and it only have to experience it for a second or 2 to roll over all the way.... How many hours of flying do you think you could get away with before a nice downdraft was gracious enough to give you said zero g event? In line thrust helps alot and it probably doesnt hurt to get anal retentive about it being as "inline" as possible... But ya STILL NEED that stabilizer..... Without that stabilizer.....you might as well just pop in an untested autoconversion and fly over the rockies for testing....probably about as risky.... go to the fly gyro forum....look at all the great stuff written by craig wall....its a REAL eye opener... sad thing is I get the impression that gyro's COULD be some of the safetest things around to fly if they werent being flown (and built) by absolute morons without stabilizers.... do an FAA database search and read all the gyro accidents....doesnt take too long actually.....virtually all the accidents are rollovers and its darn hard to rollover when you HAVE a stabilizer....without one..well....thats a different story... take care Bll |

Kevin, I'll move this to the top. The conversion improved everything.
My original RAF cruised around 60 m.p.h. Anything above felt squirrely with a lot of pitch oscillation. I then added a horizontal stab and it moved into the high 60s. After the AAI conversion, I cruise close to 80. These are m.p.h. and at minimum engine rpm to maintain altitude. Same exact engine and prop. The cross wind capability is vastly improved. With the new tall tail, the rudder pedals are probably used about 15% of the time compared to the stock RAF, and I no longer get cramps in my toes and calves from having to tap-dance constantly on the rudder pedals to fight the yawing tendency. My stick is now solid as a rock and has absolutely no twitchiness, which is the norm for a stock RAF. I know that RAF will not let a prospective customer take the stick on an orientation (introductory flight lesson) flight. AAI will hand it over almost immediately. There's that much difference. There's a link in the Groen Bros. threads named "The Blubber-butt Challenge" on the rotorcraft forum. (Link below). It's about my taking a 290 pound friend for a ride on a 100 degree day at 1400' MSL. I could never have done that in the original RAF. It was too inefficiently designed. I hardly have anything original left on mine, other than the cabin and basic engine block. I have different rotors, ignition systems, FI system, landing gear, tail and most components. The "stabilator" does absolutely nothing to counteract a power-pushover and is useless for stick-fixed stability which is the true measurement for stability in a gyro. Dofin was able to fly his stock RAF with no hands and throttle control, but if he ever locked the stick, he'd have crashed within a minute. You don't stabilize a rotor. It's always stable in a flight regimen. It's the stuff hanging below it that needs to be stabilized. The 500+ pounds of thrust that is dangerously placed almost a foot above the vertical C of G is what kills you by waiting for that opportune moment to send your ass flying over your shoulders in a forward power-pushover. The only cure is center-line thrust, not a tool shelf mounted on the upper mast. A horizontal stabilizer is a great Band-Aid, but all the force exerted by the stab to keep the tail down is just so much wasted energy. They can't give you a coherent explanation. It's smoke and mirrors and they don't have a clue to even the most basic of gyro aerodynamics. Duanne Hunn designed it. He has absolutely no credentials except he's a decent "stick." He can't talk about it. He has no clue as to what he stuck up there or what it really does....basically nothing. Who in their right mind would promote flying a gyro with a 10"+ offset thrustline without at least a horizontal stabilizer? That right there confirms RAF as idiots of the first class. They call a horizontal stab a "contraption." Another point is that their new "stabilator" will make the RAF stable. They have argued vehemently for all the years I've known them that their gyro is safe and stable. They have to this day, never admitted that that the RAF was unstable. How the hell can you come out with a stabilizing device when you never admitted that your gyro was ever unstable? They're stuck between a rock and a hard place and talking out of both sides of their mouths, with a ton of egg on their faces. Go to www.rotorcraft.com and click on the upper left instrument on the panel to get to the gyro forum. It's privately owned and there are some rules. Profanity and name-calling are reasonably controlled and everyone must I.D. themselves. Nameless trolls are simply erased. Once logged on, click on the RAF threads and then one about "Duane's contraption" or something for a very in depth disussion on it. There are some RAF apologists there and you'll see the stupidity of their arguments immediately. Most of them are semi-literate and can't spell or structure a sentence. It's a great place for anyone interested in gyros. There are some extremely talented engineers, designers, mathematicians and knowledgeable people......none of whom can grasp any critical use for the stabilator. Other components already handle the mild dampening it's capable of. As far as making an unstabbed RAF stable....pure bull****. RAF doesn't even have a pilot on staff let alone credentialed engineers or designers and never have. Their name says it all...."Rotary Air Force Marketing." Search out the threads on RAF and you'll get a good insight on their sliminess, dishonesty, lying, and tractor-grade components in critical flight components. There's enough reading that exposes them for the immoral and dishonest people they are to last a lifetime.....if you're not too young. I have first-hand knowledge. I bought and built one. Thank God I realized the necessity of a horizontal stab and the necessity to upgrade their shoddy and cheap components before I killed myself and maybe another. And now, thanks to Jim Mayfield and AAI for coming up with a safe and stable center-line conversion and soon to be kit. I'm not going to post here to argue with any RAF flacks and flunkies who may appear. They're too stupid to reason with, even when smacked directly in the face with irrefutable proof and basic physics and aerodynamics. Go to the link for really good info. If you like gyros, you'll love the place. Again, it's www.rotorcraft.com and click the link to the forum....the ROC instrument. Ken J. - Sandy Aigo Kevin O'Brien wrote in message ...

Here are 2 pertinent posts regarding RAF's "stabilator."
"Attaching a little wing to the pushrods creates a kind of semi-intelligent mother-in-law who's always got her hands on the stick along with you. She likes to keep the rotor spindle at a fixed angle to the relative wind (WHAT angle depends on the incidence of the wing). If you try to move the rotor spindle away from this fixed angle, she resists this and makes your work a little bit harder. That's not a bad thing, although it tends to duplicate the work that the offset gimbal head already does. It can't overcome the effects of a fuselage that wants to tumble, though. The stabilizing wing has to be attached to the unstable thing in order to stabilize it. In gyro low-G tumbles, the unstable thing is not the rotor. The rotor is just the victim, dragged over by an out-of-control fuselage. The stabilizer has to be bolted to the real troublemaker, the fuselage. Doug Riley" "That's not to say an aerodynamic vane linked to the rotorhead won't improve stick free rotor stability but it is no solution whatever for the basic problem of offset propeller thrust line and unstable fuselage. This is not a personal attack on Duane Hunn. Duane is a very nice person who is genuinely interested in promoting gyro safety as best he can but he's up to his ass in alligators. C.A.
