I'm about to order a plane kit (RV-10) and one of the choices I'll be making is a 3-blade vs 2-blade propeller. A 3-blade prop should be: easier to balance, quieter and capable of generating more thrust - assuming engine has adequate power - which helps to shorten the take-off distance. However, it also adds more drag (i.e. it's less efficient) so it's common to see a reduction of top-speed.
Can anyone comment on their relative performance in winds or high density altitudes? I'm not concerned about the top-speed as much as dealing with adverse weather. I plan to fly in or near the Rockies. If benefits are negligible, the cost savings are considerable when going with a 2-blade prop. I reached out to Hartzell but have not heard back.
