• If using a switch, be aware that -100% is gain off. 0% is half gain,
and 100% is full gain. "Switch" is not recommended until you've first
found adequate values with a trimmer or knob.
6. Select Next and then Apply. The receiver will reboot and first time setup
should be complete.
7. Select "Connect" to enter Forward Programming again, then go to
Gyro Settings > System Setup > Utilities > Gyro Response Test.
8. While in this page, move the model in the roll, pitch, and yaw axes. Verify
the surface responses counteract the movements. When standing behind
the model:
a. Rolling left should make the left aileron move down, and right aileron
move up.
b. Pitching down should make the elevator move up.
c. Yawing left should make the rudder move to the right.
9. Once responses are verified, the first time setup is complete!
• If directions are incorrect, make sure the model's servo reversing on
the radio was configured properly before setup. If corrections are made,
go to Forward Programming > System Setup > Relearn Servo Settings,
change All to Primary, and select Apply. This will retransfer the
relevant transmitter model settings to the receiver.
10. Before flying, make sure the gain channel (switch, knob, trimmer, etc...)
is currently set to -100% (-100% is gain off, 0% is half gain, and 100%
is full gain).
Proceed to the Basic Tuning section, or optionally, go

Basic Tuning (AS3X+ Normal Gain, No Flight Modes)
1. Follow the Basic AS3X+ Setup procedure to properly setup the gyro.
2. Before flying, verify the gyro response direction using the Gyro Response
Test menu (Forward Programming > Gyro Settings > System Setup >
Utilities > Gyro Response Test ).
3. Use the gain channel to adjust gain in flight and evaluate the gyro
response. Gain should be tuned while flying near or at max speed.
a. In most cases, the user will probably be able to find a gain channel
value that offers improved performance without additional tuning of
individual settings.
b. Due to the addition of the new parameter Stop Lock Rate delaying gain
return from centering the stick, the gain might end up too high without
the user noticing.
• In initial flights, use short/quick stick inputs to induce movement in
the model. Due to these delays, short/quick inputs will reduce gain
much less, and will allow the model to stop more with the gyro as
opposed to naturally.
• An advanced method of addressing this is to temporarily increase
