Cleared for Takeoff
My Cessna 195 has aileron trim using an adjustable tab on the right aileron and a spring incorporated into the trim system to counter the trim tab so that the plane flies wings level with the trim wheel centered. Full right releases all spring pressure and lets the trim tab do its thing..full left applies full spring pressure to offset the trim tab. I have never noticed a very big difference in the flying characteristics if not centered.
