The KC flew its re-maiden flight on Sep 2019, it is back at my shop for some minor TLC, it hasn't flow that much because my friend is so busy with his business.
I'm swapping the rudder's servo arms for JR arms and adding a drop of hot glue to the comm cable bracket on the engine, that's all, it will fly on Sat to be ready for its first jet meet at Clovis CA. next weekend.
