Pls tell me what helicopter this is - thanks.

It's a new build Merlin EH101 out of AW Yeovilton but I don't it's one built for the UK military (wrong DAS sensors on the nose). I worked on Merlin Mk3/MK3A's for 5 years at Benson so know them well.
In that case, what's with the canting of the tale rotor/fan? Does it increase tail lift? And what effect does that have on rudder control at hover and above say 100Kn. Are additional cyclic inputs required?Brink said:

However, some aircraft, notably some Sikorsky's have a very definitely canted tail rotor design:

OP, looks like Newquay Airport?

Thanks, but I know that already. My question was about the canting of the anti-torque system, whether it's a open rotor or a fenistron. Even the NOTAR system appear have an cant angle, but its subtle. Earlier helicopters have a vertically aligned tail rotor.
IIRC it's to provide an element of lift at the rail to allow a wider range of C of Gs. Yes Newquay guys.
Love the canted 'positive camber' tail rotor talk - you would have thought that neutral would be more predictable in all flight conditions.
Was just amazing to be about 400m ahead of a taking off 737 and then doing a 180 degree shot around it that was so smooth and steady. Beyond loved being surrounded by all these amazing bits of kit!
