I'm curious to hear from pilots who have flown this engine with different props.
Right now I work on Twin Otters with 3 blades, but I've heard that the 4 bladed Twotters don't have as much reverse power. My own experience taxiing the Shorts 360 with 5 blades was that it made a neat noise, but did little to slow the aircraft. Any input?

The B200 Kingair fitted with four bladed 'Raisbeck' props had better takeoff performance, climb performance and reverse performance but was slower in cruise due to the extra drag created by the extra blade. On the ground they turned slower so it was quiter taxiing that the three bladed versions.
I flew one B200 with factory fitted four bladed props of less chord than the Raisbeck examples and it performed better in all flight regimes, especially high altitude cruise.
I've never flown a five bladed equpped aircraft.
