Plane A vs Plane B

Ahh this is puzzling now...

A/8 has less induced drag but more form/parasite drag than the spit.

So Total drag = same?

It's rather puzzling looking at the parasitic drag, as I would assume prop efficiency would play a large part in the speed differences.

But the IX has a four blade prop attached to a plane with simular horse power in an inline fashion, which would probably be assumed to be better the the Fw's configuration.

However the Fw has relatively little frontal surface exposed, not to mention very large prop blades...and to top it all off the cowling fan (which probably adds very little thrust) helps  decrease back pressure through the the engine compartment (and thus decreases drag, almost like a jet engine)

hehe Not to be a butthead.. but Create the planes in X-plane then output the data for each flight, You can actually review a detailed report of all aerodynamic forces that take place within the flight as well as realtime onscreen information as well.

  Sounds like You guys are talking about X.. not aces

I'd rather go over the ungodly number of numbers in my head then let some program do it.
