Threading of 1/8" bore drive dog propeller

Brass reducer to insert into 3/16" bore prop hub to go onto 4mm shaft.

The M series are a selection of some of the X4 & X6 series props which have been modified by OCTURA by removing the ears and reprofiling the blade. This enables the prop to unload the motor. An example would be where your motor using a X447 prop was just struggling to get max perfomance and by going down to an X445 was over revving the motor, then by using the M447 this cured the problem. You still have the same pitch & diameter, but the blade area has been reduced thus unloading the motor. This is more noticable on the fast electric setups but is equally usefull on the I.C. setups.

These props have the "EARS" reprofiled to unload the resistance of the blades,

Picture shows the difference between a "X" series & an "M" series.

The OCTURA® balancer consists of an extruded ali base incorporating two parallel steel rods for the prop balancing rod to roll on. There is a levelling screw in the base and three imperial size rods for the props. 1/8", 3/16" and 1/4", which are stored in the base body, plus instructions

The M series props have been modified to help unload them by the removal of the ears.<BR><BR>  The smallest 3 blade prop for a 1/8" shaft.
