Default 3 blade prop manufacturers

I've got a fascination with three blade props. Why? I dunno, and I'm aware of the supposed inefficiency of the extra blade.
When I purchased my plane it come with a Graupner 3 blade. Well, it lasted exactly one very short flight, so I really don't know how good it was.

I bought a Master Airscrew 3 blade, but I've since realized how much the MAS props flex.

From the looks of it APC only offers one 3 blade, a 15.75 x something so I guess that's out.

Anyone have experience with the Graupner props? Are there any other brands out there worth using?

I can't seem to find any more, although I'm sure there must be. I'd like to keep the Nylon/glass filled. No wood props for me just yet.


Oh, and it's for a .61 2-stroke so something like a 12-5 or a 11-7 three blade is what I've looking for.

Thanks for the help

I believe Masters makse some good wooden three blades. I understand Graupner makes very good 3 blade props. APC makes more than one three blade, but I don't know if they make anything in the size you need. For a .61 two stroke I would be looking at a 11-5, 11-6, or 10-7.

I went from a 15x8 to a 3 blade 14x7 Master prop on my Top Flite T-34 with a YS 120 and the performance was better.

Zinger makes 2, 3, and 4 bladed props. I have always wanted to buy one, but haven't got my airplane put together yet. Anyway here is there website. http://www.zingerpropeller.com/ I like that you can buy replacement blades in case you break just one. Not sure how the hub works either. Just another option!

Sport Pilot: For a .61 two stroke I would be looking at a 11-5, 11-6, or 10-7.
Really? I thought that would be a little on the small side. I like the larger diameter props. Maybe I'll try the 11-6 if I can find it.

Macdona: I went from a 15x8 to a 3 blade 14x7 Master prop on my Top Flite T-34 with a YS 120 and the performance was better
I'm trying to stay away from the MAS props. When I've compared them to another prop of the same size, MAS comes out on the bottom. I think they just flex too much..... Even though I used to be a die hard MAS fan.

Spitfire: Zinger! Why didn't I come up with that? I'll check them.

Hobby Lobby International sells Graupner 3 blades. Not Hobby Lobby the craft store. Do a search and you'll see what I mean.
