Auto info

Hi all

Started doing autos with my raptor 50 yesterday and was really enjoying them and used up 2 tanks doing them,
Now iv always known rule of thumb is when learning to do autos is to do them into wind, but my question is that the wind will never be blowing the same direction at the field so if i do an auto with the wind what should i look out for? and what should i expect and be ready for??

cheers all

Wind allows you to have the same air speed with less ground speed. So it will be coming in hotter and the flare will add less head speed.Andy

depending on how much wind you wont be able to stop a 50 downwind either more of a sliding auto.. As BH says you will also have to come in hot.

Depending on which blades you use, about a $200 to $250 repair bill!

The government cannot give you anything without first taking it from someone else.

Start learning autos from both sides, it's uncomfortable at first but a necessity. That way you will still be doing them into wind if the wind changes direction. Best NOT to do them downwind unless you got a rich daddy lol.

When autoing with the wind you need, as stated before, come in at high speed. Thats easily achievable if you perform a dive before leveling close to the ground and come in at "high speed, low approach".

I find crosswinds much funnier though. Come in normally but let the heli tilt enough to get some wind "under" the blade during the flare. Should spool up those blades pretty ok

A really hard landing. So hard you may not be able to take off because of your broken blades.

Seems to be the simple answer really

The reason for my question on this, is on sunday i was doing some autos but had to move down the field and go far left, but i was think is the wind comes in from behind me i cant go down the field and face the Pitts,
just getting some info just in case of a engine cut and i have the wind behind me

thanks all for the info good stuff

You may get stuck in a situation where you have to auto with the wind.. Just be mindful that its not going to be as pretty of a stop as the ones that you do against the wind.. You will probably have to try and flare back a little even after you touch down and keep the front of the skids up to keep from catching on things as you slide by them.. Now if its just a little breeze this is not an issue although even in a slight breeze an auto will feel different with it than against it. But with a wind your going to have to come in hot and be prepared to slide a bit.

It is best not to auto with the wind on purpose and only use it for emergency needs only

You auto into the wind for two main reasons:

1. Airspeed vs groundspeed. If there is a 10 MPH wind and you are lanidng at 10 MPH into the wind your ground speed will be zero. However if you are landing at 10 MPH with a 10 MPH tail wind you will be landing at 20 MPH.

2. When you flare at the bottom of the auto into the wind, you are exposing the bottom of the disk to the relative wind. This will actually help speed up your blades.If you are WITH the wind when you flare, you expose the top of the disk and that will not help speed up the disk.

If you can, you should always try to auto into the wind..If you have a flameout, kick the tail around.

If you can't you may need to do a running landing.

I had an engine quit down wind with 15 to 20mph gusts. I knew I didn't have much to flare into so I didn't try. I let it slide and that is one reason my skids look like this:
