Well no, the rotor system was a big improvement over the L2, very smooth at high speed and high weight. The EFIS is still the best IMO - simple but effective. By comparison, that on the S92 and the AW189 look like the scribbling of a child, far too much information, not at all calm, logical and inuitive as the 225 is. The engines became less smokey after a mod to the oil breather system. Rotor de icing was available, just not needed our side of the N Sea.
The 175 May or not be a good helicopter, too soon to know if it has a fatal flaw. And I didn’t like it not having a centre screen, bad HMI because it means that when something goes wrong you have to use one of the screens for system info, which means the PF and PM do not have the same info. How can you be an effective PM if your screens aren’t showing the same as PF?
But unfortunately a helicopter is only as good as its weakest link.
