No. The opposed 2 cylinder shakes along the Z (vertical) axis. A 2 blade that is phased with the crank is going to have less stress on the crank and less shake than any number of blades, other than a single bladed prop.Would it help this problem since there will be no blade corresponding to any combination at tdc?
The counter weights on an opposed 2 cylinder, like the 1/2 VW and the O-100 have their counterweights arranged to reduce this shake - thus the external counter weight on the prop flange of some.
