I guess some guys never listen or learn

R44 Pilots Operating Handbook - Section 2 - Limitations: Aerobatic flight is prohibited!

Wasn't there a 407 in SA that did a very expensive loop on camera a couple of years ago!? Bell made them change parts worth around $ 1 mil after that one.

Don't really see the problem. He's doing somewhat of a "wingover", no loop or even close to a loop for that matter. The camera angel fools you a little

I'm quite sure that is a model helicopter and by the sound it just might be jet turbine powered.

BTW it is perfectly easy to loop a model helicopter with a teetering head rotor system. You just need lots of speed before entry otherwise you dont make it around before getting a mast bump - which isnt serious as the masts are usually solid steel and they wont break very easily.

I cant think of a real helicopter with the required grunt.

oow

For freshman flyers .. please be sure to read the word "model" in the above statement as attempting a loop or roll with an underslung system in a full size aircraft and it's likely to be the last thing you do!

If you must loop .. then this is how to do it:

...and if anyone wishes to copy the actions of Dennis 'The Maestro' Kenyon's antics, as seen on Savoia's link, just remember even Maestro's cock it all up eventually!!!

The Lynx was back-flipping, not looping.

Rotor separation what...?

No neg G but probably 10Gs at the end. Good luck to whoever flies that one

Cock-up

Yes, the Salt Lake City accident surely qualifies as a master cock-up, and just goes to prove that even after that particular 'wing-over' manoeuvre had been publicly performed around two and a half thousand times, a small drop in self discipline and peripheral awareness bites back hard.

SLC airfield ... 5,800 ft ASL, temperature +96 degrees F ... So just to say please don't try this at home without some guidance from a qualified DAE. Best wishes to all loopers. Dennis K.

Loops

Oh ... and to keep the record straight, the video clip embedded by Savoia was the Enstrom version of a Loop performed at North Weald. The accident Salt Lake City Sikorsky 300C manoeuvre was a 'nil power wing-over.' For the uninformed - not a lot of difference perhaps. DRK

"Don't f***ing loop them unless it says in the flight manual you can" would have to be the definitive answer on the subject, I'd have thought!
