Surprised that no one mentioned horsepower is not even a measurable specification? (its the product of a formula)

Its based solely on torque and rpm....

that's what saudrauker was getting at......... :D

and it was all gone over in another thread///////

BTW>>>>>>>


horsepower, torque don't propel our airplanes.


THRUST propesl our airplanes.  :devil

Skuzzy.

This -->  :D  <--- is apparently no longer sufficient to denote playful sarcasm.

We need a more effective smiley guy.

I always wonder why, if you're going to spend the time/money to build a replica, build it 75% scale? is it purely the additional cost of suitable powerplants?

For 75% scale, one possibility could be the 601cid Falconer V-12 used in the ~75% sized Thunder Mustang.

65000$ per engine. :)

 What I've always wondered about these sort of accounts is, if you scale down an aircraft, does the same aerodynamics apply?
 
 I do know for a fact that an increase or decrease in scale requires a lot higher adjustment in power since the overall volume is affected at a much higher rate than just the scale... but what about the aerodynamics? The wind-tunnel testings would obviously mean that the way the air flows around the aircraft doesn't change with scale... but what I'm talking about is, if one changes the scale of a plane, but cannot exactly adjust the weight accordingly (due to problems like limited engine choices..) - wouldn't this mean the plane needs some sort of adjustments to the design to compensate for it?

The propellers seem to be counter rotating but to the opposite direction than in the full size plane.

Otherwise that is a very cool plane.

Even at 75% of original size that bomber is pretty big. Id make a hole for R2D2 behind the cockpit though.

No, it's not. But then, it isn't big enough, either.

Imo you don't need engines that big as I doubt the guy rides his P38 at 350mph  :old:

wouldn't modern 400hp engines do the job ?
