Hughes,
I am a fan of the 66 because of its performance. That's all. 5 up, 3/4 fuel, OGE hover at 75%. You simply cannot do that in a jetty.
Your criticism of weight saving does not make sense. Indeed, that's what everyone in aviation, from a model aircraft to the space shuttle is trying to achieve.
TTB,
Well said, the first bit anyway. That would be why Robbies are the biggest selling helis in the world.
Anyway, good flying to all.
