Servo Ty e Selection
The GA-250 was designed to work with all modern digital tail servos. DO NOT use analogue tail servos!! There are
different types of digital servos and incorrect settings may damage your servo and possibly loss of tail control during
flight. So please make sure that this step is done FIRST!
To access the servo configuration mode do the following: power on your gyro and when the status light flashes blue
toggle the gain switch on your transmitter three times or more in quick succession (ending in AVCS). You are now in
Servo Type Setting mode. By pulling the rudder stick left or right you alter the servo type. The number of red flashes
indicates the currently selected servo type.
