One of the more interesting features of the P-38 was that its counter rotating props both rotate in a direction that shifts the resultant thrust outboard on the wing. Evidently this was to improve accuracy in gunnery, but it would make flying on a single engine more difficult.

I’ve never seen a p 38 in person but I’ve seen pictures of one along side
Of a p51. The p38 was huge in comparison

Give Me Operations
(As recorded by Oscar Brand)

Don’t give me a P-38; the props, they counter-rotate
She’s scattered and smitten from Burma to Britain
Don’t give me a P-38, NO!

CHORUS:
Give me operations way out on some lonely atoll
For I am too young to die; I just want to grow old

Don’t give me a P-39; the engine is mounted behind
She’ll tumble and spin, and she’ll auger you in
Don’t give me a P-39

CHORUS

Don’t give me a Peter-four-oh; it’s a hell of an airplane, I know
A ground-looping bastard, you’re sure to get plastered
Don’t give me a Peter-four-oh

CHORUS

Don’t give me an 86D, with rockets, radar, and AB
She’s fast, I don’t care; she blows up in mid-air
Don’t give me an 86D

CHORUS

Don’t give me an F-84, she’s just a ground-loving whore
She’ll whine and she’ll wheeze and make straight for the trees
Don’t give me an F-84

Just give me operations way out on some lonely atoll
For I am too young to die; I just want to grow old

Could you explain? I understand how the props transmit torque to the wings and how counter-rotating props cancel out each other's torque, but I don't understand how the thrust vector would be moved off line from the prop axis.

I'm not saying you're wrong; I just don't understand how that works.

A link to an explanation would be just as good, if the explanation is long, and you don't want to write it all out.

Thanks.
