RE: Right thrust and 3D
I am trying to figure out what the difference is between hovering upright; and hovering inverted...[sm=bananahead.gif]
Since there is none, any plane that has a conventional vertical stabilizer, will fall to the left, needing right-rudder to correct.
If prop rotation is the other way, this plane will fall to the right... Since nearly all engines rotate in the same bearing, there is no need for us to worry. We always need right-rudder and not to need it, we need to build in right-thrust.
Mike (Salmon) put it the right way.
Bruce, you may have good 3D flying instinct, but I believe you did not correctly explain this (post #4).
