First thing is to put it down in t hold out of a low hover.

Hover at 3 ft and hit t hold. see how it hangs and you can hold it off the ground at a few inches by feeding in positive (don't do it too high up). Once its down put negativeon to hold it down.
Increase the height up to about eye level. Now any higher and you enter the "dead mans curve" where it is had to put it down nicely with the rotor momentum, and there in't enough height to get it gliding to speed the rotor up with an auto proper.
Real helis avoid the dead mans curve, and they hover either low, or go fast and low, or hover high - so they can get a glide going and land. slow and quite high is where they will die if the engine stops.

Now you can put the heli down with just the rotor mometum from the hover, yuo need to get the heli to thid point from fast forward flight with the engine off.

1. Make sure the trims are set the same in t hold as they are in the flight mode you will enter auto from (I only just realised that was why I was fighting to keep it level in elevator!)

2. foward speed, load of forward speed. Helps if its windy.

3. zero or negative pitch with the heli going fast and nose level (this makes for max head speed to start with). hit t hold.

4. during descent keep the nose level or a little down to keep the thing going fast toward the landing spot. control the descent with neg pitch from 0 to -4 or so. It can actually float along at +a tiny bit and maintain head speed but just a little too much plus and the head speed falls rapidly so take care.

(you can abort out of this by hitting the switch while you stil have somke height. Even have a mate stoodf there operating the t hold switch in case you are freeze).

5. It should approach the landing spot going fast at about 30 degrees angle of glide descent now as it gets low round out nose up with slight negative pitch and the rotors will spin up faster as you kill the forward speed. Work the pitch so it doesn't climb. level it off so now you are at about 3 -5 ft with a good rotor speed - and the landing is like the first practice above.

Thanks for that!
I tried what you said... works. Except I am using the 'gear' switch on my DX7 as the hold button, and it's hard to flick it while flying... and I can't get the proper (top right) hold button to work for some reason...
Anyways, here's what I was able to do. Look OK? Attached REC file... using the Trex500, so you might need that installed to view...

moyesboy gives good advice but you will find it so much easyer on the flying site than on the sim just dont give positive too soon. I had some great ones to day was at the field for just over eight hours today, got through 7 1/2 lit. of magum 30% thats about £30 worth this is the best way to learn.

3dee, is it easier in real life? I'm petrified for my first attempt. But should be fun. I think getting it down on the sim, before trying it in real isn't a bad thing, I guess. It's cheaper!

A gallon and a half...
...not all auto practice then! or is your tick over a bit rich?

Sarcasm at its very best..
