I can't remember the advantages/disadvantages between a 2 and 3 bladed prop. I can think of a few:
Two blades:
1. Pro: less drag with two vs three surfaces
2. Con: longer blade required for same power reduces ground clearance
3. Pro: Less cost for overhaul/purchase
Three blades:
1. Pro: Higher off of ground for better clearance
2. Con: higher cost
3. Pro: faster RPM due to speed of sound issues at tips
I'm looking at Cessna 182's right now for possible purchase next year.
Thanks!
