How could I have forgotten the throttles???
It's just criminal negligence to have the throttles on the floor, or on the ceiling, or anywhere else but on the collective. So you might have to pay Bell a little for patent licensing - I feel for you, but I just can't reach you. That's my #1 complaint about Sikorsky - overall a great helicopter, but those throttles are just ridiculous.
Fix this, & I'll forgive you for the leaks.
