Yes, what Tx do use presently? Most are putting the gyro gain on the flap switch setup to be the flight mode switch too. The way the gyro knows to be in bank one or bank two is whether the signal is negative or positive. Example, bank 1(-), flaps up, rate mode, nws gain off, bank 1(-) t/o rate mode nws steering active, bank 2 (+), landing flaps holding hold mode, nws active. The difference is in the T/O mode switch position the radio has to output a positive signal to know you want the bank 2 settings which can be heading hold or rate mode on any of the cortex outputs.
