With c/g in center of envelope, the aircraft is still tail heavy. It pitch up too fast after TO, even with trim in front of white band. And very sluggish on landing.
Must load with c/g nose heavy to make a stable flight.
It feels that white band painted to far back. I cannot imagine a c/g with trim in the middle of white band.
All trim in my flights are from the front end of white band and forward..
