Final Approach
A friend of mine had to replace the props on his Seneca, they were two blades and he was debating on the 3 blade vs 2 blade props. I vote 3 blade, because they look cool and 99% of the time the props aren’t moving!!My C414 has strakes. Frankly I don’t notice anything, so I believe any improvements are nominal. When I put the STEC 3100 the plane definitely suffered from Dutch roll. The strakes were not enough. Added the 3100 yaw damper and the roll problem totally went away.
but they look cool.
