Autos are touchy, I learned to do them using a Kalt ZR Enforcer with flapping head.

I would practice flaring the heli and then I would do these up high and fly away. On my fourth practice run it was so smooth I went ahead and landed anyway.

After I felt comfortable flaring, I used the hold switch. I would descend at low stick (-3 degrees), began to flare, and then I would turn off the throttle hold so I could just do a fly by instead of a auto. I practiced quite a few times, every time flaring even lower.

I then began to flare at 3to5 feet until I was ready to auto and actually do the landing without pulling out of it. After a few careful but sucessful autos, it began to get easier as time went by. And finally doing a nose in auto was a lot harder early on.

But you have to keep your heli correctly lined up-wind is a factor as well....Posts above have good pointers for this..

This is my personal setup to doing-practicing an auto-Do it your own way as my preferences only fitted my needs. Do So at your own risk!
