Hughes 500 is a turbine but as i own 2 of them and 2 300's for training was pointing out that the rules prevent a safer helicopter ie the 60 year old piston engine we have to put up with in the training environment.
Thank you with the 355 I am a TRE so do know that a fully loaded one, if one of the engine goes the other is taking you to the scene of the crash unless you get past 30 kts from a helipad takeoff.
