to get the finest movement resolution possible, use whatever ratio is equal to making the motor pull
to get the finest movement resolution possible, use whatever ratio is equal to making the motor pulley just about complete a full revolution. an example with easy numbers: if your full stick travel is 36deg, 360/36 = 10:1. A 90t pulley to a 9t motor pulley would match, but you can use a 10t on the motor to keep it under a full rotation so there's no power-on issue with centering.
