Thanks Aegir,
I've just sent an inquiry email to Air corporate, an Italian TRTO .
By the way, after calling I got an answer from Multiflight. Very prompt to answer after that.
Dragon helicopters also answered: not possible, no helicopter.
PDG Helicopters: not possible to busy. Answered quickly and very friendly.
Heli-avaition.de: they are studying if it's possible; waiting.
NHV: answered.
Well that's where it stands now.
Cheers
