You don't see four-blade props very often. I wonder if that is the "new thing"?

Actually they've been around for a number of years in very limited quantities, but I don't think anyone is making them anymore!
In fact Carbon props in general are getting very scarce!

Brian Eather made the only four blades I'm aware of. He made me a some props about 2 years ago. He comes in and out of retirement occasionally to make a few. Don't know his current situation.

NO not really
Bolly made many 4 blades before that, I sold many to CL stunt guys in 10 10.5 , 11, and 12 , 12.5 inch 4 blades
Ronnie Farmer, Bob Gieske , Jim Casales , I used some of them as well as dozens of others going back to the 1980s, may wanna look at Dougie too :-)
I even have 4 blade spinners

I used a Bolly 12-4.5 4 blade on a PA65 in a Trivial Pursuit for a long time. Great combination until I broke it on a rough take off one day!!! Bummer! Couldn't find another one! Went back to a 12.25 4.5 three blade...OK but never quite got it to work as well in the wind!

Randy I remember Casales with one but didn't know the brand. That's about when my missing era began so ..... Surprised I haven't seen them around. The sense I have about the ones I have is they seem to run a little smoother with less vibration than a three blade. Might just be happenstance or maybe another dynamic.

Yes the 4 blades run smooth , 1 reason is the flywheel effect, they weigh a little more, and thus run smooth, you also can run less diameter, only disadvantage I saw was they are louder

Jimmy used a 11 x 7 Bolly 4-blade for a while, I know that much.
