Default 3 Blade Prop + DA85

I'm looking at the new XOAR WW2 3 blade props and I'm wondering if I should wait for one or move along. The problem being DA recommends the Mejzlik 24x12 3 blade but the closest with the XOAR lineup is a 26x10 3 blade. I'm guessing it might be alright after break in as well as the Mejzlik. Seems rather large considering the break in prop is a 26x10 which some seem to stick with.

Any facts/experience is welcome!

Thanks

Xoar can make any prop you want if you order it. If you want a 3 blade 24x12 Xoar, Abell has them in stock. Not it the WW2 though, just in beech. If you talk to your prop dealer they should be able to order any prop you want, you just need to wait until they put in their next order. I even have some laminated 3 blade props that they don't list.

Jeff is our man at Thunderbolt, I didn't know they would allow for a custom order; I'll have to check into that.
Thanks!

I wouldn't mind hearing from DA85 owners running 3 blades now!

That looks like advertisement. Would be nice to hear from owners of DA-85 that have flown or are flying 3 blade props.

Thanks

I have no direct experience with the DA-85 but I do have an MVVS 80cc mounted in my Zero and on that, I have a Xoar 26x10 3-blade prop.
The MVVS spins this prop with ease and I have found that this is an excellent combination on this plane (30lbs roughly)
Assuming the power output of the DA-85 is similar to the MVVS80 (different torque curve probably), this prop should be a good match as long as it's a similar plane

Hey 183, Ive got a NIB DA85 to go on my P47 and am in the same position...wondering which prop! For six years I have ran DA100 with 27X10 with great luck and know that the guys with the 85 are running the 26X10 with the same kind for success. I also ran 25X12 3 blades on the 100 which was and excellent combo. The rule to follow, as I was told by some expert 3D guys is when you go to a 3 blade prop, you drop diameter 2" and go up in pitch 2 degrees. So, since the guys are having such good success with the 26X10 2 blade, its only fair to assume the 24X12 would be the way to go. Thats the route I plan on taking unless someone with more knowledge tells me otherwise. Personal experience tells me it will be right, based on the DA100 success. By the way, I plan on trying a Solo 4 blade on the 85!! You think 22X14? Here we go again
Hope this helps

Go low if you wanna make a show

I'm putting the mezlik 24x12 3 bl on a 3W 80cc, which is close to the DA 85, and will put that on the Ziroli P40, weighing about 36 lbs.
Waiting for the weather to improve before doing maiden flight. I'd love to hear anyone numbers from guys trying the Xoars with 24x10 or 24x12 3 bl.
I have run a xoar 24x10 2 bl with DA 85, was getting 7800 rpm and took a 22-23 lbs 95" Yak on balistic runs. I will use the 24x10 2 bl as maiden flight prop on a DA 85 inside a TF GS P47 86" before using my spendy Fuchs 21x11 4 bl prop. Just waiting for weather to improve to fly these giant warbirds with different prop combos.
