I find a handful of right aileron trim useful when circuiting the carrier. I have it bound to a knob on my throttle control box (WW Orion). Rudder and elevator trim on my stick as I need them all the time. All my warbirds including Tomcat are like this (Spit has none). Aileron is a lesser trim so I moved it off the stick, but still handy nearby. Trim trim trim. Keep that ball centered.
