"M" SERIES Props
 
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.
