German BO105 TV clip
I don't know if this has been posted already.

There's a couple of minutes of general chit-chat before the flying starts.
I just wish I knew some German so I could tell what the presenter says at the end. I think I have an idea and it isn't "Thank You".

They are talking about how long the pilot could do this. His answer is: "after half an hour, i also need a bit of rest but then i start from the beginning".
Then the reporter asks him how long it lasted, and the answer is: "about 10 minutes".

How long does it take to get used to aerobatics like that? Or even just the simple low-G pushover sensations? I still feel my stomach rise momentarily when bottoming the collective. Does that sensation eventually go away?

We used to regularly roll and backflip the Lynx during our 4 Lynx routine in the early 90s and you do get used to it but it still isn't that nice - You have to get used to the fact that you're always within 1% of certain disaster and there is no room for error.

Did you find that the articulated head made a big difference? I'm not sure how much difference the control system makes in a Lynx, but i noticed the pilot kept positive g throughout the B105 manouvres. Man, that takes skill though...

[Edit: replacing word "rigid" with "articulated" - never sure which i should really be using, since the objective is rigid flapping and lead-lag just allows for blade flex. Corrected misunderstanding that pilot was the late great Ziggy Hoffman]

The pilot in the clip is not Ziggy , he died during the making of a film about helicopters in the early 90's . There is a clip of one of his demo's that is even crazier then the recent German tv version. Including end over end summersaults ( for want of a better word) and rotation about the mast while in a vertical dive. There was an urban legend about the Lynx that an early test pilot put a permenant set in the titanium dogbone after attempting a barrel roll to close to the ground

Thanks widgeon, post corrected.
Which part of the Lynx control system is the dogbone? I take it though, that the Lynx control system results in an extremely manouvreable heli? My interest stems from the fact that this is (i understand) an electronic update on the AH56 system. See:

I have been away from the lynx for some years so my info may be incorrect.
The lynx has a semi rigid rotor head with only the feathering hinge being a bearing.
THe flapping is handled by the titanium main rotor hub ( the Cutlet ) . The lead lag as i recall by the titanium member outboard of the hub ( the dogbone ) , so named for its shape.
The original Lynx blades were bonded stainless steel and extremely rigid.( also a nightmare to manufacture)
http://www.b-domke.de/AviationImages...head/0282.html
the dogbone is the member fwd of the lag damper.
The 105 has a composite main rotor blade attatched to the titanium hub via a titanium cuff in the end of the blade , there are TT straps that link the 2 opposite blades. Feathering is like the lynx via a bearing . The lead lag and flapping hinges are actually the section of the blade before the trailing edge attaches. Considering the amount of bending happening at the blade root it is a credit to the designers that there has not been a single blade failure on a 105 though there has been a catastrophic failure of the TT straps.

Safety pins in the picture are the blade fole quick release pins
