I think this helicopter will be great in a couple of years, as the post above I have experienced a few hick up's..
Cracked tail booms
Cracked exhausts
No2 engine started to spool up as the Aux switch was turned on

Windows falling out
Had 3 engines have to be shut down in flight
Hyd failures
But I'm sure once all the gliches are ironed out, this will be a wondeful aircraft. I enjoyed flying it immensly..
