Using the tail gyro gain to activate AttitudeControl, how can I control AttitudeControl and switch the tail gyro gain with flight mode switch?

If applicable you may use the free programmable mixing functions of your transmitter to mix your AttitudeControl switch on the tail gyro gain output. To enable AttitudeControl you must reverse the sign of the tail gyro gain channel. So by flipping the AttitudeControl switch you must subtract or add enough channel output so that the gyro gain channel will give the amount of desired AttitudeControl gain. In the following example it is shown how this may work out on a Spektrum DX18. We use switch H to activate/deactivate AttidueControl. The AttitudeControl gain is 50% (-50% channel output in this example).

Create a new programmable mixer	Here we just use a very simple mixer from Switch H to GYR channel	As the gyro channel (GYR) is 50% at the moment we subtract 100%	So when flipping the switch the channel moves to -50%

We use a mixer from switch H to the GYR channel that subtracts 100% when flipping the switch. As the gyro gain may differ between different flight modes you can create one mixer for each flight mode. Each mixer subtracts as much as necessary to get always the same amount of AttitudeControl gain (in our example -50%).

Mix1 subtracts 100% to get -50% in flight mode 1	Create a similar mixer for flight mode 2	In flight mode 2 gyro gain is 58%	Mix2 subtracts 108% to get -50% in flight mode 2	Create additional mixer for the other flight modes if necessary
