It’s all in the rotor head. And a few other structural parts, I guess. But the rotor head design is what makes todays helicopters either aerobatic or not.
Those are some awesome ships. As a helicopter owner/pilot, I can say that the real impressive part is how agile they are for their size and utility.
We have a 530F that can run circles around it as far as speed and maneuverability is concerned. But, the two are apples and oranges as far as their utility as a helicopter goes. The BO is without a doubt at “sports-tank” in the helicopter world. An absolutely all around awesome ship.
I’ve rolled our 530 twice. Non-consecutively. But will never try to loop it. I wouldn’t want to see what happens if I screwed up and fell back over on the head with too much Neg-G loading.
That would be a very bad thing.
Thanks for the awesome videos.
