MT-Propeller has introduced its first-ever warbird propeller.
The new 4-blade propeller was recently certified by EASA, with FAA certification in the works. Initial certification was for the Twin Mustang F82, but the propeller can also be installed on the P-51, according to officials with the German company.
“By designing this brand-new propeller model, MT-Propeller has solved the problem that it is becoming increasingly difficult sourcing old airworthy propeller parts to keep those aircraft flying,” company officials said, noting the F82 has “already accumulated many flying hours with the new propeller, flying across the U.S to attend air shows.”
The new prop’s power rating is certified up to 2200 shp, according to company officials, who said “this will cover most of the applications requiring such a propeller system.”
While the propeller looks like the original classic propeller, the blades are made of natural composite material with an aluminum hub and a steel spline adapter for the #50 spline.

What is a “natural composite”? The wood core might be natural, but epoxy infused synthetic fabric is about as far from “natural” as possible. I don’t have anything against composite props. Just call them what they are. Typically a wood core with a carbon epoxy composite surface, although other materials are also used. If all of the components are natural materials, I’d like to know what they are because I’m not aware of any composite construction that only uses all natural materials.
You might want to look it up, but high-strength “bio-epoxies” have been around for a while now … epoxy resins made from veggie oils. They’re strong too. We fired 9mm [jacketed] and .45Cal [lead slug] at non-reinforced pours of 20-25 mm thickness. The 9 barely pierced and merely dented the plywood backer board, and the 45 slug mushroomed, bounced off the epoxy, and landed on the tin roof over us.
That was 14 years ago.
Looks great I wish I had a double Mustang like that we’re even a regular single piece 51 keep up the good work looks great
What are the speed and climb gains from the new prop? Its looks to have more surface area so is the performance stats different?
