Set up your servos as you normally would on the radio (I am going to assume that the servos are identical except that one is reversed). Set your dual rates as you normally would. Then fine tune on the matchbox. If your servos are matched at neutral but skew at full throw in either direction, something is wrong with your servo. If your setup is a mirror image from one servo to the other and the geometries are matched, the matchbox would line up the servos and would continue to deliver equal proportion to both sides. There is no reason why the servos would not reach the identical end-point. [:'(] The only thing you could do is change the end point at the matchbox for the one servo if you could not do it at the radio. You could have even reversed the servo at the matchbox.[sm=thumbup.gif]
