NR Propeller

I don't have confirmation but I suspect my Meglin prop is also from the same molds as NR, Luga, etc. The blades look suspiciously identical in shape. Workmanship on the blades and hub is fantastic.

I have told many times about Ukrainian propeller manufacturers and developers.
The Lugansk firm AERO provided thousands of our aviators with plastic propellers with classic shaped blades.
Then Lugaprop was spun off from it, and they began to work in parallel.
In 1993 in Kharkov two of our designers Pavel Dimitrov and Anatoly Vasiliev designed and started production of propeller VN-1 at our firm Lilienthal.
In 1995 it turned into a propeller with saber-shaped blades VN-3 Donchak. Its properties surpassed all known propellers at that time.
But in the future the quality of blade manufacturing fell. Lugaprop manufacturing quality has always been excellent and stable.
Around 2010 I managed to convince Lugaprop to buy the right to produce VN-3 Donchak propeller and join efforts to produce saber-shaped and classic blades.
Lugaprop was able to significantly expand the range of propellers produced. At this time NR-prop was separated from Lugaprop.
Later their paths diverged and now the nomenclature is different. Lugaprop now operates in Russia.
We in Kharkiv continue to work closely with NR-prop, which was forced to move from Lugansk to Kiev.
Our nomenclature of Meglin propellers is identical, the production of both classic and saber-shaped propellers has been preserved.
Ellipse-shaped blades have also appeared, as well as especially strong blades designed for engines without gearboxes or engines with increased power.
These blades were developed at the request of American pilots, owners of RV aircraft with Lycoming engines. Similar blades are also used by Jabiru owners.
We also try to keep the production of wooden propellers and various auxiliary products listed on the website: http://propeller.mozello.com/

35 deg C is like spring and fall here in Tucson. so I guess it is only good for 3 years at 110 deg F

Good Idea, I think I will need the flange bolts also, mine are too long.
