A four blade propeller can be configured a blade every 90*, a blade alternately at different angles like 60*/120*, or stacked like a bi-plane. What is the reasoning behind choosing one configuration over another?
In a 60*/120* type configuration which blade should lead the forward blade or the rearward blade?4 BLADE PROPELLER.png 4 BLADE PROPELLER 90.png 4 BLADE PROPELLERS STACKED.png
