Master Airscrew Propellers

Master Airscrew propellers offer 8 product series based on the application, size and characteristics from light electric motors to 4-stroke gas and glow engines. In this repository, technical data on Master Airscrew propellers are grouped into three files by the propulsion system type. Propellers are available in various sizes, ranging from 5 to 24 inches in diameter, and in pusher and tractor configurations for twin-engine aircraft and multicopters.

The normal direction of rotation (also known as tractor or standard) is established when a propeller is rotating counterclockwise (CCW), as seen by an outside observer standing in front of the propeller and looking at it.  Reverse direction of rotation (also known as P-type or pusher) is established when a propeller is rotating clockwise (CW), as seen by an outside observer standing in front of the propeller and looking at it.

3-blade model airplane propellers specially developed for the most demanding hobby professionals. They have great performance and suite both for electric motors and glow engines. Props are manufactured from Glass Fiber Reinforced Composite. 3-blade propellers are available in sizes 5" to 16".

This series of propellers is characterized by a blade shape designed for maximum performance, low noise level, and high stability. The universal bore is made to fit different shaft diameters with the help of the enclosed reducers and therefore offers a lot of flexibility when selecting the right motor shafts.
