Herkimer OK Cub 14

In Stock at the Trading Post








The Herkimer OK Cub 14 Vintage Glow Model Airplane Engine was designed and manufactured in the U.S.A. circa 1952. The design featured a unique array of 4 radial exhaust ports and transfer channels.These engines were intended for control line and free flight use. The 14 size was part of a line of  engines all of similar design and ranged in displacements from 0.039 to 0.19 cubic inches. This popular engine design was considered to be light and powerful in it's time

Specifications:-
Displacement           0.149 Cubic Inches;
Bore                        0.60 Inches;
Stroke                     0.53 Inches;
Weight                     2.25 Ounces;
Max Speed              15,000 RPM      

Two versions of this engine are shown here running with tractor and pusher propellers on 15% Nitro Glow Fuel and swinging 10X6 inch propellers. The pusher version was probably intended for powering boats. Note the difference in the two versions is the thrust bearing on the pusher located just aft of the drive washer.
