I flew my plane for a second time with good power from the RCV 58CD 4-stroke engine. It stalled while approaching the landing field, but showed a very nice balanced descent that confirms two lead weights to the tail were correct for achieving its CG. It appears the tail heavy turning behavior is most engine torque when turning left.

I experienced a stall on take-off of its 3rd flight, but thankfully not yet airborne, while at full throttle. After two hours of erratic engine behavior with numerous adjustments, included a flooded engine, I pulled the engine to figure out it had a RCV 58CD carb barrel screw retention problem. This will be fixed with replacements of 2ea new carb dog point screws and 2ea 3mm steel split lock washers to use with these screws from BJ's Model Engine Service.

After this fix, just more flying of this very nice ARF Aero Subaru by GK Models. which had several of my AMA members asking to learn more about it.
