Because of inherent design issues with a three cylinder design, Volkswagen
used a balancer shaft to qwell vibrations and the result is an extremely
smooth engine.

I wonder if the shaft balancer will be as smooth in an airplane, since it is
driving the prop, instead of the road. It *seems* like it should be as
good, but I still wonder.

should be.

my experience with these balancers was in a 250cc Kawasaki single pot.
most incredibly vibration free installation I've encountered.
the balancers are balancing rotating mass imbalances within the
engine.
done properly the technique is impressive for what it achieves.
