Hi guys. I haven't posted much in this area as I consider myself a novice flyer, not really into all the contest maneuvers. In fact, I can't even tell you what what different classes of competition there are, but I LOVE flying my heli, and have made good progress.
Started flying in march, and have had a couple of different birds. Right now I'm flying a very upgraded Raptor 50.
I do loops, rolls, tornados (nose down), fast backward flight w/loops, inverted flight forward, back, and hover both ways inverted. I decided it was time to try AUTOS!!!

Last week I decided to try autos for the first time. I autoed the Raptor down to about 40 feet off the deck from a 100' altitude. I flared a little, hit the hold switch back on, and took off. That was fun! so I tried it again, dropped from 100 to about 30-40', and hit the hold again to power up, and guess what........no engine! I had set my hold RPM too low, and it flamed out. So here I am, in my 2nd auto, 40' off the deck with a decayed head speed, and no engine! I dropped the stick, dropped like a rock, and flared/positive collective at the last second, and it landed!!!! I returned home to change my shorts, then came back out to fly!

I've been doing autos (mostly ugly ones) ever since with no mishaps! I am soooo excited to get better at them! A couple of guys at the field are very good at them, so I hope to learn from them to spot land, etc...

Anyway, just thought I'd pass the good news on, and tell any other newbies to check their throttle hold settings before they lose it in an auto!!!!

Well done on the autos. I've been trying to get the balls to do the same, but both times I did an auto out of choice, it cost me a bit...

The 3 times that I have had to auto were absolute beauties - strange that...

Hi,

good done, this little practise save your heli.
Auto's are realy fun to do, i know alot of pilots doing 3D stuff all te time, but auto's.... they can do it.
Well, last week i did a backwarts loop wen the engine dies at the moment i was backwarts up and nose down, about 60 feet high, and gues... i set the heli ( raptor 60 ) down very smoot, thanks to the practise of auto's al the time, my goal is at the end off a flight everytime a do a auto. You will see, you wil be better afther a wile, wen the engine stops, never paniks and keep the sticks smoot and under control.

Happy landings, and welkom in the real world......of auto's.

Kind regards

Very good Dr Tooth!
I have not been so fortunate in the past...several colisions with boom and blades. BUT, today I actually did a hand full of them and without incident I wanted to do more but the "just one more" syndrome over ruled, so I stopped. However I think I'm on the right track. Just a side note.. I too was worried about flame out and have my th set alittle on the hi side so thats not a problem. I guess I'm cheating on my auto's but I needed to start somewhere!

Nate Woddops (sp sorry Nate) gave me this idea a few months back. Instead of upping your throttle hold and "cheating the auto" try practicing the approach in normal mode.
If you think about it you are doing the same thing in that below 1/2 stick the heli is decending in a semi free wheel state. Then you can abort the auto anytime you like with just application of the collective.
I tried it till I got the hang of the approach and the start of the flare now I am hitting the hold switch. So far only one oops and that was due to the crappy field (landed with one skid in a small hole. :mad)

good ideas

The idea about descending in normal mode at your idle or just above idle is a great one. The first couple of times you do that it's a little scary. Trying to maneuver the heli in a fast descent and keep in on track are hard for beginners. I am glad I had the juevos to overcome my fear and just do a couple after some dry runs. Sure makes it easier now!

Good luck to all in their quest for the perfect auto!

Autos

Trevor, glad to hear the bird is all better.

The idea of flying the approach in normal is a great one. I try to fly at least 1/2 a tank each outing doing the 45 degree transitional approach to a touch and go. I do them from all directions, left, right and straight in. The normal mode allows for some comfort level even on a botched approach. Face it, eventually, most of us will have that emergency, botch the approach and still have to try and save it. Autoing practice has saved my birds at least 5 or 6 times in the past year. Trevor can attest to the fact that I do roughly 1/2 of each tank practicing autos.

I did my first intentional auto 15 months ago, I can now do 180 degree turns, pirouetting, and as of last Sunday I added some really ugly inverted autos. Most of the time I can come close to an 18 inch target.

Sim, sim, and more sim will help with the first intentional autos, tighten your blades, check your idle in normal & Thr. hold, fly the approaches in normal, and wait for a light breeze. This is a vital skill to this hobby!!!

flip autos.....(>o<)...

Hi guysF
I like to do autos after every aerobatics,engine-cut auto is more funny than idle one!The f/backward 180 /2-90 degrees are so easy to do w/R30(w/auto hub),but I still practice flip autos on com simu!could any guys give me some advice to control rotorspeed to do flip autos!
Thanks a lot

I like to do a lot of hovering autos too. Just to get the feel of how much inertia is left over. I do this with a new heli also to get the feel of the throttle hold switch. I also set the sim up for random engine failures and see how I do.

It paid off one day this summer. I was out doing a bunch of moving flips and thought I could get one more in before running the tank dry, NOT. It was inverted and nose in to me when the thing quit. I continued the flip and entered auto, hit the throttle hold out of habit. I was about 30' up and way out away from me, 120' or so. I thought it was crash time but I kept my cool and figured that all I can do is try. It worked, no damage.

Autos are a blast. As someone mentioned, some 3D flyers don't do them but they are missing out.

To hover is divine, the alternative is rather PLANE.

G2 saved a R30 last week

I fly the Real Flight G2 sim alot in the winter when the days are short. My goal is to try new things and practice old things and not crash. I want to land after every flight or do a successful auto when it runs out of gas. All of this on the sim. For about an hour the other night my 8 year old was killing the engine with the keyboard while I was practicing. It paid of big time. I was test flying a R30 for a friend and on the second tank, I was inverted at about 30 feet when the engine quit. I rolled it upright autod it really well although it landed about 50 feet away. About the time it touched down I realized this was for real.

Last second of Autos

I still not really sucess any hi auto yet. I had try low auto from 2', 10' and 20'. No problem with throttle hold position (engine just turn fast enough to turn the blades). So I tried to set the throttle hold position to idle, than I flew it up to about 30', and hold switch, heli just came down so quick, I add more pitch, no help becayse I just slow the blades down, heli droped like a rock and broke the landing gear. Just wondering if I have too much pitch? When I slip the throttle switch, I was at 6 degree pitch, should I move it down to 2 or 3 degree while no engine power?
Than I try the high auto, flew to about 100' and slowly drop the pitch to the bottom, heli just drop like a rock and fast......really scare me, is this normal? I just have no nerve to let it come down to 30' and add pitch.

Sparrow,

You can't auto well from 30'. To practice, you should do the following:

Make sure you have your stuff set up right: An example,

Set your throttle hold throttle to be sure it will run on hold, and not die. Also, keep your mixtures good. If it's too rich, it may die when you abort an auto and go off throttle hold.

Next, make sure you have full negative pitch in both normal mode, and throttle hold, and max pitch at full collective in both modes.

go up to 100'. don't hit hold. Just drop your stick down and let the heli fall, and when you get about 10' off the ground, go ahead and give it throttle and pull out. Do this a few times to get a feel for the descent of the heli.

Then go up to 100' and hit hold. Drop your left stick almost all the way down. Yes, your heli will drop like a rock!!!!! But that drop is speeding up the head. When you get about 30' off the ground, give it collective and get a feel for how much collective you need to arrest the fall. Immediately take it off throttle hold and abort the auto. Do this SEVERAL times until you get comfy with the descent, and lift generated.

The next step is the real thing. A mistake beginners make is giving positive pitch too early. You really need to wait until the heli is about head height or a little higher, and don't STAB the collective up. Push it up to about 1/2 stick(2or 3 degrees pos pitch) and smoothly push it up from there until the heli gently settles on the ground.

Try this with help from an experienced pilot. Have one auto your ship a few times and help you with setup modifications before you do it on your own.

Good luck, and happy autos!!!!

Tanks Trevor

Your instruction is very simple and clear. I can't wait to try it. On my 9Zwc2, I have throttle hold and hold funtions, I usually use throttle hold only because it only hold the throttle and nothing else. Which means when I fly in normal mode, when I hit the throttle hold, only throttle will hold, everything else will funtioning the way they are. I never use hold funtion from flight condition manu. So if I set up the posotive +10 and negative -9 in normal mode, it will the smae when I hit throttle hold. Is it sounds normal to you? Now I have -4 and it already drop like a rock, if I have -9, it will drop even faster, wouldn't it? I am just so affair that the heli fall right into the ground.

pitch

Sparrow,

The problem with having only -4, is that you can't descend fast enough with that to store up enough energy in the spinning blades. Don't get me wrong, you can auto like that, but it's better if you can get your blades really fast. It gives you more to work with at the bottom of your auto.

Good luck. If the fog lifts here, I'm out tomorrow practicing more autos!
