It's getting pretty boring here. So, who has done an actual emergency
autorotation and what was the outcome? As previously posted, I've done at least five with various failures and all to successful conclusions. Geeez guys....it's Christmas! Can't we say something or do something to brighten up the spirit of the season? I have a phyxed wing student who just did a terrible landing recovery this week and jammed the nose wheel up into the cowling doing about 30K of damage to a C172SP. Curled the prop and all. Talk about a dampener to the Xmas spirit? So, what have you done lately? Anything to brighten up the day? Ol Shy & Bashful |

I've done a bunch through the years. Actually, most of the "unexpected"
engine out auto's I've done were pretty much uneventul. Even entered a couple of them from inverted but had enough altitude to deal with it. Dropped the collective, hit throttle hold, and split S'd to upright and put the bird on the ground. The first "oh sh**" auto I ever did, which occured while I was actually practicing to "learn" how to do auto's, was the result of a tail rotor failure. That one was "real" interesting but successful nontheless. I wish I could claim skill on that one however it was nothing but dumb luck. I'll take luck over skill any time! ;-) Fly Safe, Steve R.

Oops. Sorry guys, wrong newgroup. One of the pitfalls for loitering
around one geared to the full size birds and one geared to the RC versions. Please ignore the previous post. Fly Safe, Steve R. "Ol Shy & Bashful" wrote in message ups.com...

Ol Shy & Bashful So far I've only had one engine failure (piston) - it happened on the ground during the run up! Best engine out procedure I ever handled The school here has had a few though. Pistons like to quit during practice autos just to check you really had a good place to go when you chopped the throttle. They've all ended up OK.... However, a few autos to the ground (engine still working), that haven't been so successful - definitely seems that practicing for autos is more dangerous than the real thing... Merry Christmas guys.

Heres a new one for the books and possibly stir things up a little. I once
had to do an auto from about 500 ft AGL but with a power recovery. When doing my warm-up I noticed the rotors spool up a little more than normal but didn't think to much of it at the time. Once all the temps were in the green I set out and departed and all seemed normal. Once at altitude I notice that my EGT's would sky rocket as soon as I reduced the throttle for cruise, did I mention I was in a Mini 500. The mini has two sets of carburater jets, one for cruise, and one for higher power settings. So my only option I could see at the time was to keep climbing or go faster, both using the higher power setting, or auto back to my departure point. I did a quick circuit back so as to auto into wind and then cut the throttle to idle and entered the auto. At the bottom of the auto I did a power recovery at about 10 ft agl and set it down uneventfully, changed the jets to richer ones and set off again with no problems. Just goes to show that I should have noticed that with the rotors spooling up at idle (slightly higher engine RPM do to the leaner jets) I should have looked into what was the cause. I should also mention that this was the only engine problem I had in appox. 300 hrs of flying the Mini. Kirt "Stuart & Kathryn Fields" wrote in message .. . At first, I only read these with interest and then I remembered that I did have the engine quit one day and I successfully set it down. I had about 12 hrs total helo time and was in the process of hovering off some test time on my Baby Belle. The mixture at idle was a little rich so I tweaked the mixture back until the engine ran smooth while I warmed it up. When it was ready, I lifted off into a hover and the engine quit. Too lean a mixture for full power. I had never practiced a hovering auto in my ship yet but I guess the reflex action was correct. Thanks to "Ol Shy & Bashful"'s posting, I now can say I have had an auto to the ground. This one was so quick I didn't have time to get scared. -- Stuart Fields "Toad-Man" wrote in message 1...

Didn't you get the other post I made "immediately" after posting this one?
It was a sincere apology for not paying more attention to "which" newsgroup I was responding to. And "yes," it was an RC model. Although I'd love to see a full size bird do an autorotative split-S! ;-) Fly Safe, Steve R. (who's appropriately embarrassed!)

This is the group where we talk about full scale Steve, not the models.

Yeah, I saw it, but about 2 mins after I posted. No need to be embarassed. I had to double check the group name after reading your post a few times. And I was visualizing the maneuver. Later I saw it was for RC's but have never seen one in person. There was a great video out there somewhere which, to me, was awe inspiring. I don't know how that guy did it but I was sitting on the edge of my chair. -- boB, SAG 70 U.S. Army Aviation (retired) Central Texas - 5NM West of Gray Army Airfield (KGRK) |

We were at the Spurling helicopter fly-in in Ok. and had finished flying for
the day and were sipping on some beer when some young guy with some lady in what looked liked business attire, came out to the edge of the runway and set a RC helo down and started fooling with it. As hard as a helicopter is to fly with all of the butt feedback, we pretty much backed away a bit to get out of the shrapnel zone of broken blades. Pretty soon the RC helo lifted off and it became apparent that this guy had a smoke system on board. Some of the maneuvers this guy did had all of the helo pilots that were standing around bending and wiggling their hands trying to figure out just what control inputs would be required to do what we were seeing. One of the maneuvers was a backward flight up a 45 degree line performing rolls. A split S auto would be a piece of cake for this guy. We later found out that he was the current National Champion RC helo driver and the lady with him was his corporate sponsor. Even tho this has been about three years ago, I can remember my mouth hanging open and saying things like: "Holy schit did you see that?" Until it got boring to repeat myself. We also found out that his helicopter greatly exceeded the 10#/hp rule of thumb. -- Stuart Fields Experimental Helo magazine P. O.
