I was stunned when I discovered that the B2B uses a vertically running

vertically running engine because it does not have a gearbox.

So, you're telling us that the Exec rotor runs at engine speed?

No, I didn't say that at all. The exec has no gearboxes at all. Not
even a tail rotor gearbox.


I have to say that I never realized that Lycoming even made a vertical
version of the O-360.

And, you are also telling us you've never seen a Bell 47 (not the ones
with the Franklin)?

I am saying that I have never seen under the covers of a Bell 47 so I
don't have a clue what's under there. Apparently helicopters with
vertical engines are more common than I thought. However, it still
seems kind of silly when there is a gearbox being used that could
easily convert the direction.
