any advantageous using the 3-blade at T/O at all? and if a 3-blade is used compared to a 2-blade, would that affect the cruise speed? i would imagine it all really depends on the thrust that one prop can produce. what about the amount of vibration?
and would the 3-blade produce more thrust at the same rpm?
slower response time... so... would it be less efficient in terms of feul comsumption?
