Left & right DC-3 engines?

[AJW]

Both engines on the default DC-3 rotate in the same direction, which would creat a helluva asymetrical torque effect. Is there a way to edit the .cfg file so there is a "left" engine and a "right" engine?

huh? That is normal for the DC-3...put the rudder in and get her off the tail wheel ASAP.

That is standard in most multi's execpt for Counter Rotating props found on some Seneca's and Navajo's and a couple other aircraft.

Torque is one of those hard to see things that don't seem to follow the rules, If you have the inclination, look it up in a high school physics book, but basically if you have 2 sources of torque (engines) at each end of a beam (wing) the net rotation effect at the centre of the beam (fuselage) is zero no matter how the engines rotate. The difference comes down to how the wing spar absorbs the load as an additive bending moment or as a shearing load.

Hope that makes a bit of sense.
Next lesson is gyroscopice precession!!

Thanks for the info about the Senecas, Navajos and other twin engine aicraft. I was aware that not all twins' engines rotate in the same direction, but did not know for sure about the DC-3.

It's a rare aircraft that has counter-rotating props. The P-38 in WW II was the first I'm aware of, though it's likely that there were some others before that.

Although it provides an improved behavior with an engine out, there's not much difference with both engines running, and it's expensive to build two versions of the same engine, so the aircraft built this way are scarce.
