I would also like to ask if there are any glaring advantages pertaining to a contra vs a single propeller setup. I really like the concept of simplicity and less weight of the single prop but could be swayed.
As always your opinions are valued.

I have been flying an Anthem swept wing.with a Debowski contra. Theory says that the swept wing is more stable in yaw. In practice, in comparison with my Element, the Anthem does seem to be more stable in the upline in yaw. An ellipitical wing does not possess the same yaw "stability" but gives an ideal lift distribution. IMHO, there is less difference between a single and contra prop but a bigger difference in airframe effect. For example, with the same contra (CRS) my Element was better than my Agenda. The Anthem was another step up from the Element albeit it had a different contra setup. I'm sure with a single prop it would be just as good. The only difference is that the rolling speed for a contra is the same either way whereas for a single prop the roll is slightly faster with torque than against it.
