How do you do this....

Check out the helo video thread and watch the NH90 demo at the Australian Airshow. It can be viewed on page 2.

It is quite spectacular but I wonder if anyone has any insight and information on how to do this stuff without over-torquing or excessively G-loading the aircraft at the bottom of these manouvers?

I have some ideas but I am interested to hear yours.
If someone can post the link then I would be appreciative

NH 90' demo

It's quite a big file. Best to right-click on the link and 'Save target as ....' especially if you're on a dial-up connection.

Impressive a/c and pilot! Excellent video, I especially liked the gasps and sighs of the cameraman. He must be a helicopter pilot watching the demo pilots extra nine lives tick away.

Its only about a 2 hour download on my dial up.

Mr. Boutry, chief testpilot at Eurocopter France, is flying this demo and he is as far as I know the only person performing this manoeuvre in the NH90 (sofar).

I am pretty sure the G-forces at the bottom are not the most difficult part of this manoeuvre, and this aircraft is one of the prototypes (instrumented aircraft) with a G-meter in the cockpit.

I admit that together with everybody else I was also impressed with the manoeuvre when I saw it for the first time.
