Config 6/7 Holding Power
It is a function to adjust the posture holding force of the aircraft in AVCS
mode. Decreasing the value weakens the holding power and makes the operation
feeling closer to the normal mode. The current rate numbers Cl to C5 are
displayed by operating the channel of the transmitter. Like the flight
condition function of the transmitter, you can set up to 5 different data for
the attitude holding force rate of the aircraft in AVCS mode by operating the
switch from the transmitter, and switch between them. You can set the holding
power rate selector switch to the channel with the AFR function of the
transmitter, and set the point for each rate on the AFR point curve to switch.
It is also possible to use the light condition function to work with the light
condition switch. 
Config 7/7 Reset
Reset each Config item. It returns to the initial value.
SBUS Basic menu
Set the CH for each function according to the transmitter to be used. Any unused functions should be set to INH (Inhibited). The channel of each function can be changed.
WARNING
Always verify that the S.BUS function assignments match your transmitterʼ s function (in the FUNCTION menu) assignments. If any changes are made within the transmitter function assignments, then it will also be necessary to make the changes within the S.BUS function assignments. To change the channel, GYA553 and T32MZ must be connected.
