jmacg8r,

I can't explain in details how autorotation works, because I don't have a heli with autorotation, neither I've ever seen one doing what's suposed to do, but from as far as I know, it is a system that minimizes the damage caused to a helicopter with autorotation, in the event that it falls down. - Even the real size helicopters as far as I know if not all, most of them have autorotation safety mechanism.

Don't do as I said turn the TX off to try, as someone else explained to you already, that will make the heli fall down as a rock. I have no idea how you test it, and all I know is that it protects a heli with autorotation from getting destroyed if it falls from a high alttitude. Seems like you have to manuveur a bit before it lands for autorotation to work, but I think it's alot easier to land it under that circumstance compared to a heli without autorotation.... in other words your forced landing will be alot smoother than with a heli without autorotation.

It has to do with negative pitch at the time of landing, those the heli tries not to fall down as hard as the normal way without autorotation.... like saying "I don't want to fall..." so by changing the blades to a negative pitch, it tries to land as smooth as possible, but you have to control that yourself a bit before landing.

Look at Heliko's post, go to those links and learn how it works. ;-)
