If you have an early 9Z, the software suffered from a slower frame rate. A slightly but notable mixed/slave servo was not uncommon. Later TX models addressed this issue.

my zap9 is one of the first models and i think that this problem of the software is not the only one if you have to use several mixed/servos .I have suffer a lot of times trying to setup radio gear to models that required more that 3 servo for flaperons and speed breaks .
