Yes=2C every choice has its pros and cons. If it hadn't been for my MG proj
ect=2C I would have been quite happy to carry on with the Warp Drive. It pe
rformed well=2C and you can't beat the exterior carbon finish=2C as opposed
to painted or varnished propellers.
But I also had to have feathering=2C and the Airmaster hub had become very
expensive. I am not really wild about automatic pitch control=3B I would pr
efer just manual=2C with an accurate display in percent or degrees of pitch
. I don't think there is such an animal.

Cost I suspect. Most things are a compromise

Why do most GA aircraft have 2-blade props ?

in theory only is a 2 blade more efficient=2C you get more vibration that c
an't be balanced out. More vibration gives more disruption to laminar flow
so more drag.
This is also why 2 blade windmills are more likely to throw blades. 2 blade
s don't cope with non axial air flow=2C multi blades do

Get a two blade prop. One blade of a CS prop is 4Kg's worth. Apart from
that=2C it cruises more efficiently=2C cutting down on fuel (read: weight).
