De Havilland Mosquito

       Aerodynamically or otherwise?

Not always true. Some have both engines as critical!

[PR19_Kit]

   Trust me, unless you have counter rotating props, you have torque & it has to be corrected with rudder. Ask a multi-engined rated pilot rather than modelers. Without reading the article, critical engine has to do with prop rotation direction & which side of the a/c it's on. An a/c with counter rotating engines has no critical engine, but that's different from having torque.

I think I already said that........

How long could a Mosquito handle Hanoi before rotting?   

[The Wooksta!]

Look at the Mosquitos in the far east post war.  Not long!

     I guess you did, kind of.

     Trust me,

I'll take you at your word, but I'm still looking for an explanation of how this works, since it goes against all of my physics knowledge. I'm probably overlooking something, but what?

Hobbes, check your PMs

You're thinking of each engine as a separate structure and not connected to the fuselage or its opposite number. The torque effect of each engine acts on the WHOLE structure and not just itself and the fuselage.

A high fuel fraction means less weapons load. Not a problem for a gunfighter like the Zero, but doesn't bode well for a bomber.

What are you talking about?  Most of the bombers had higher fuel fractions than the fighters did including the Mosquito.

Totally agreed, and the Corsair, Bearcat, Thunderbolt and B-17 were handicapped by their radials... 

Well, the B-17 and B-24 had less range than the Avro Lancaster did technically

The Hornet and Twin Mustang had handed props and engines but very few other twins of the WWII period did.

The P-38 did...

The P-38..

Dunno, but I don't know if it really matters as I was thinking of a fictitious design with a radial engine and metal-construction.  I don't know if there'd innately be any weight problems if it was designed right.

Got it.  Thanks again.

The operative words in my posting were 'VERY FEW'..........

You were talking about taking a Mosquito and increasing its fuel fraction. If you do that inside the existing airframe, a decreased weapons load is inevitable.

P-factor is a separate phenomenon (asymmetric forces acting on the control surfaces) that will cause a similar effect (roll depending on the power setting).

This design isn't necessarily going to be an exact copy of a Mosquito with a radial and a higher fuel fraction.  I'm talking about a different design that is designed around the same concept fictitiously in the same era.

BTW: When were the first laminar flow foils like those used on the P-51 first researched?
