Multi blade propellers for F2D 3 and 4 blade propellers for combat First published: 1/4 2014 - Last update: 1/4 2014 - By Henning Forbech

New propellers for Combat:

How many blades should a combat propeller have. 1, 2, 3, 4 or even more?

Some interesting information can be found in this paper on propeller performance: Propeller Performance Data at Low Reynolds Numbers (4.2 Mb pdf)

A simple way to see if multi blade propeller will perform better than traditional two blade propellers it to make a test flight.

By replacing the prop nut by an extended nut it is possible to mount two propellers on an engine. To compensate for the extra weight of the second propeller the aluminum back plate can be replaced by a light weight plastic back plate .

3 blade combat propeller

A special nut will let you mount two propellers on the engine
