I was very disappointed with Helitech2015, I certainly won't be going to RAI Amsterdam for the next one. As others have commented about lack of people like Sloane, RotorTech, Sikorsky et al, can't agree more, even Airbus and Agusta were not really that interesting.
The one thing in its favour was its ease of access, just a few minutes from LCY, but the organisers seem to have lost the plot of what Helitech was about.
