Default Light twins not using contra-rotating propellers

Not mentioned by other posters is that stability in twins can be affected by
which way the props rotate. The P-38 Lightning and Ted Smith Aerostar are
examples of this. Counter-rotate the props one way and get better
performance at the cost of stability. Turn the props in the opposite
direction and get better stability at the cost of performance.


These aircraft allow you to select the rotation direction of the
props?


No, different models of the same aircraft turned the engines different ways.
For example:

First P-38: http://p-38online.com/images/xp381.jpg

Second P-38: http://p-38online.com/images/yp38grnd.jpg

Look at the direction of rotation of the port engine.
