       Stihl 4-Mix,Saito,etc.

       I understand that this design is essentially the same as the
       aero-modeler  Saito engine. Has anyone successfully converted a
       4-Mix for R/C aircraft use? Personally,I don't like the '4-Mix'
       engine design when used in a blower/trimmer; apparently  Stihl
       believes that this design would still be allowed should all
       traditional 2-stroke engines  stop being produced.......I don't
       believe that either will occur-after all,the 4-Mix engine still
       requires the oil/gas mixture that causes the alleged pollution
       when burnt ,regardless of how many valves the design has....

       Some people think the lower pitch of the exhaust note of the
       four stroke to be more pleasing to the ear?
       The four strokes do have more torque
