Got to hand it to you AnFI, you are always good to pep up a thread or two for a few pages until it all gets google-eyed bananas.
You are of course right in one respect in particular: If they hadn‘t been flying that over-designed, overpowered helicopter, they would have had less of a yaw emergency to deal with. But don‘t waste your time here, write directly to the Japanese Police and paint a different, lower risk future.
btw you need to check in more often or pay more attention: Crab flies this type and will know very well how ugly LOTRT issues are in it.
