Tonytech2, the Hermes 1 & the Hastings look very similar, they were essentially the same apart from the windows. The Hastings was not pressurized & I'm fairly sure that the Hermes 1 wasn't either. The Hermes 2 was longer & pressurized but still a tail dragger, it was the Hermes 2 design that was modified into the Hermes 4. The sole Hermes 2 outlived the last operational Hermes 4 by 4 years.
FAStoat that was fascinating & rather worrying info on the Centaurus. I hope they can be kept viable for a few more years, despite the obvious advantages of the US engine conversion the sound of a Centaurus with its five bladed prop is simply to die for.
