And with them going in OPPOSITE directions too!

The MC-72 only had two bladers as well, perhaps it was a 'style' thing of the times?

Can you imagine the sound though with twin V-12's and two- two bladed props?!      Glorious or shrikeing? Both?   

And with them going in OPPOSITE directions too! 

Probably give the Thunderscreech a run for its money

The majority of the early contra-prop systems
used two-bladed props. Which isn't surprising
as two-bladed props were still very common.
There is no reason it would be louder than any
other contra-prop setup, arguably it could be
quieter as there would be fewer crossings of
blades, thus less airflow interference than with
a three-bladed system. 

As an aside the most efficient propeller design of
all, in terms of using available power, is a counter
-balanced single bladed propeller as it has the
least amount of drag to overcome.
