AttitudeControl with combined switch channel

If the tail gyro gain channel is also used for AttitudeControl (see chapter 4), then there is the following difference to the operation mode with separate channel as described above: In the switch position where AttitudeControl is off, the channel deflection determines the amount of tail gyro gain as usual. Increase or decrease the (servo) throw of this channel to adjust the tail gyro gain. The amount of tail gyro gain is indicated by the yellow Menu-LEDs each time after initialization procedure and always when the gain changes. Here the Status LED lights up in blue color. When you flip the switch and the channel is deflected to the other direction, MICROBEAST PLUS will keep the current tail gyro gain and activate AttitudeControl. When adjusting the height of deflection of the channel into this direction you can specify the AttitudeControl gain like described above. So here one channel is used for two functions. Depending on the direction you can either adjust tail gyro gain or AttitudeControl gain and by switching between directions AttitudeControl is activated or deactivated.

When using AttitudeControl with combined switch channel make sure AttitudeControl is at least deactivated once before take off. Otherwise the tail gyro gain would be minimal as the system would not have been able to determine your tail gain adjustment after initialization.

In this mode it is absolutely necessary to use a switch that changes the control directions directly and without intermediate steps. In particular, do not use a slider on the transmitter! Otherwise, when you activate AttitudeControl the tail gyro sensitivity would be decreased to 0% before the system turns on the AttitudeControl. So you would have 0% of tail gyro gain when AttitudeControl is active.

Note for software versions before 4.1.x: When AttitudeControl is enabled in general the tail gyro can not be used in Normal-Rate mode. If operating AttitudeControl with separate switch channel (see above) the channel for tail gyro gain activates HeadingLock - Mode in both directions. The sign of deflection is not relevant here, just the amount of deflection is important. When you also want to use the tail gyro in Normal-Rate mode (as described here) you must disable AttitudeControl at Parameter menu point I (by setting the Status-LED to „off“ state).
