From my perspective there is no particular funny behavior. I am certainly not complaining about the Lynx, old or new. All of the charactoristics are known and explained, none are dangerous. True, there is an increase in vibration in the hover and at low speed, but that is a result of high energy vortices rolling off the tips and interacting with following blades. It is not ideal for roles requiring long periods of hover, but it's much better at speed. As always with helos there is a trade off!
