This is my third Cardinal, To me all mine seems to want to hesitate before they turned. On my first cardinal I made a larger stab and elevator which worked OK. The second one I put more elevator throw then the flaps That worked OK but I always thought the flaps were to large. My third one was an ARF and I didn’t like the covering so I striped off the old covering and monokoted and cut 9 inches off the flaps. FOR ME the plane turns quicker in the turns. It doesn't turn any tighter just quicker.
