Tom,
You may already be aware of what I’m about to write but this is for the benefit of those who are coming late to the 9303. The reason for using the dual/mate function in the WING TYPE menu instead of a program mix for dual ailerons, elevators, flaps, or rudders, is that a program mix is a less powerful mix for coupling dual surfaces than the dual/mate function. A program mix carries only a few specific master channel’s attributes over to the slave channel. Trim is not one of those attributes! More than once there have been posts from people who have coupled their dual ailerons with a program mix asking why the aileron trim only affects the right aileron and not the left. The dual/mate carries all the master channel attributes over to the slave channel.
Some attributes require that the servos for dual surfaces rotate in opposite directions. For example when an aileron command is given to a plane set up for dual ailerons, normally you want both aileron servos rotate in the same direction. It is the linkage geometry that causes one aileron to go up and the other to go down. With the ailerons are used as flaperons, the servos have to rotate in opposite directions. Were a program mix used to couple the dual ailerons, two flaperon mixes have to be used. One mix using a positive rate to one aileron; another mix using a negative rate to the other aileron. The dual/mate function automatically takes care of this and the only mix you have to set up when using a NORMAL wing type is a flap-to-flaperon mix. With a FLAPERON wing type, you don’t have to think about it.
