{short description of image}

    The perfect two-stroke engines for high performance .40 to lightweight .60 size aircraft.  These engines feature a superior fuel delivery system with fuel tank pressurization, butterfly type throttle and new carburetor design for instant throttle response.  The carburetor uses simplified construction that does not require adjustment other than the familiar needle valve.   Low speed is factory preset with adjustment of the throttle transition set by changing the diaphragm valve.


RPM Range:     2,000 to 18,000 RPM
Prop Sizes:       9 X 8 to 11 X 7
Weight:            14.2 oz.
