Eastern Aircraft (Grumman) FM-2 
 

The KMC conversion parts and instructions.  The rudder needed modification as the aerodynamic counterbalance came down too far.  The lower part was cut off and attached
to the fin so that it looked more like photos to me.  I didn't use the cowl except as a guide for positioning the cowl flaps, which caused trouble because they were too low
 on the cowl and did not align with the exhaust depressions.  The cowl didn't fit the Tamiya kit very well.  They tell you to put inlet ducts in the bottom of the cowl which is not
accurate for the FM-2.  They do tell you to remove the magnetos from the kit engine but you are still left with the wrong number of cylinders and incorrect nose section.
