Learning to fly helis. When your nitro dies in flight do you turn into the wind to land? Like we do with planes. Thanks

If you can. It's easier to auto into the wind. Going with the wind you can get into your helis down draft of air and it takes a lot of energy at the bottom of an auto to get out of it. Without your engines power you may not make it.

Yes. If you can, try to point the nose in the direction of the wind.

There is much more involved in an auto than wind. (pitch, throttle cut, collective)

If you need more info, just let us know.

Good luck.

This is a relative of the "downwind turn" BS for plankers.

The real answer is: It does not matter if you are into the wind, cross wind, or downwind.

You must maintain a certain AIRSPEED to preform a successful autorotation (heli) or "dead stick landing" (planker).

Airspeed is not related to the direction / speed across the ground.
EG: If I am "hovering" in a 10 MPH crosswind, I am "stationary" relative to the ground. But, I am actually flying sideways at 10 MPH to maintain that position relative to the ground.

You could say that turning into the wind would help minimize the speed of the heli across the ground.
But, realistically, the heli will be perfectly happy doing an autorotation going BACKWARDS, sideways or upside down.

not true, you need to arrest the forward speed relative to the ground so wind direction matter a lot. Downwind auto's are heli killers, especially if you are not experienced with auto's.

Learn auto's on a day with a light, steady breeze and shoot them straight into the wind. Keep the rotor disk at absolutely flat as you can, maintain forward airspeed until you are at about chest hight, flair back to stop the forward movement, relative to the ground and maintaining a bit of negative collective. Then level off and just land. I shoot auto's in every flight

EDIT: I may have mis-understood what I read. Yes, you can shoot an auto tail first or even sideways but at least with a sideways you'll use up more of your energy pushing the heli sideways in the relative wind. Plus that would be a tricky auto. I do spin the heli around once I'm down on the deck but tail first auto's are harder because the orientation is funky and the tail is using more energy to keep it straight. Nose first auto's into the wind don't even need a tail rotor at all (non-drive tail)

I feel it necessary to reiterate the OP post, as we can keep the information simple for him.

Autos
Thanks for the help.when I am on the sim. When you are down wind I can't bring her back to the runway. With the wind I can have more forward flight. But sounds like I need to prac. Authoring into the wind.

The first objective when auto rotating should be to get the heli on the ground safely don't worry about getting back to you just pick a safe spot to land and then get it down quick. Helis don't have the glide ratio like planks.

1st auto
I remember my 1st UNPLANED auto. My brother and I were playing around at the field one day. We both just got started in Helis about 6 month prior to this. (Been flying planks all our lives.) We heard about Drag racing. After everyone else left the field and only him and I was left, we decided to give it a try. (Drag racing) We both lined up to do a start out across the field. He gave the go and we both took off screaming across the runway. While mine flamed out and he yelled give negative pitch and level it out. I did, it came down real fast but I flared at the bottom and landed on the skids. I was surprise I did it without much thought. Later I was doing them on purpose and crashed several times.

BTW we were flying Raptor 30s.

Is it the weekend yet?

No, you just go a little below half collective and fine tune your cyclic to keep the air flowing into the blades. Ive never taken wind into consideration and have done many hundreds of autos. It would be more important with a 450 size but you can pull it off in any direction.

If your motor dies and you have to do a forced auto unless your up high I would just worry about getting the heli safely on the ground. Forget about wind and attempting to return to the heli pad . You need to be more concerned firstly with NOT killing any head speed you still have and finding the closest and safest place to land..
If you up high and your proficient at autos the you can start looking at where to land, wind direction...etc.. Your prior with autos is blade speed and maintaining it... Everything else comes 2nd. You stall the blades you become a falling rock...

I will never forget my first auto. It was a flame out at about 50 feet high. I had just went into FF from takeoff. Worn out YS on a heli I bought used. It was only my second flight on a 50 size nitro. Everyone was watching. Lol. I got her down with barely a bounce. Man my nerves were shot. Lol.
