What prop will work best on the Brison 3.2 In a Aeroworks 29% Edge? Set up will be for 3D.
Thanks for your replies

We switched to a Menz 22x8 S on this setup and it works much better for 3D than the 22x8 Mejzlik we were using. The down side is it is a bit noisier. Good luck.

Great question, I've been debating this myself. I've got a Brison 3.2 in a Lanier CAP. I've tried a 20x10, a 21x10 and a 22x8. I kinda like the 22" prop for landing approaches----it slows the plane down nicely (bigger prop arc acts better as a brake??). My 22" prop is a relatively inexpensive wood prop----and its very noisy. The 21x10 is a carbon fiber prop----the plane is much quieter and seems to be more efficient (lower rpms and lower throttle settings). Problem is that both 10 pitch props give the plane more speed, even at lower throttle settings. Plane is much harder to slow down on landing approaches. Seems like I can't find the optimal balance between these props. If any of you have got any ideas,.....WarpedWing.

Try the Pro Zingers from 22-6 to 22-10, one of them will make you smile.

I would recommend that you use a 22/8 or look at some of the carbon props that may be in slightly larger sizes. Keep your RPM's down under 7500 and things should run and sound good.

While you may be able to get a lot of thrust with the 22/8, if your engine speed is too high, you may have too much prop noise.

Geistware, not to start an argument here but Carroll specifically said 3-D. The very nature of 3-D and high alfa flight requires RPM's in the mid to upper rpm range where throttle response is at its best. The Brison should twist 7200-7500 static according to Gary Allison at Brison engines. 3-D is throttle happy flying and if you can't use your left thumb your not ready to try. As far as prop noise, the shape of the tip has a lot to do with that. I think a Pro Zinger at 7000 makes less noise than a Master at 6000.

I was reading the Aeroworks flight results on the new version of their 29% Edge 540 with a Brison 3.2 and they used the Menz 20x10 standard. They seemed to like this prop so I think I'll get one and see.
I also have a BME with a Mez. 22x8 on the flat tail Aeroworks Edge and it works well also and quiet which I like. I may try this prop also and compare.
Got some good replies and I thank all for the suggestions.

I have the edge with a 3.2 brison on her, I found for all aound flying a Menz 21 x 10 has worked well to include 3d. The RCS 22 x 10 was a very good prop for 3d. I have ran the following:

22 x 10 Menz 6400
21 x 10 Menz 6700
22 x 8 Menz can't remember
21 x 10 Mezlick 7500
22 x 10 RCS 6200-6300
22 x 10 zinger 6100
