Troubleshooting / F.A.Q.
Question: Is it OK to use expanded rates / ranges on my transmitter?
Answer: While using expanded servo ranges on your controller will not cause problems, they are not needed and may cause confusion.
The Guardian will use its own expanded ranges depending on your gains, and any Custom Servo Ranges that may be defined through the
PC App. In both 2D and 3D Modes, higher gains will result in an improved responsiveness. In 3D Mode, activating Direct Rate 3D
Control and increasing the Direct Rate Speed for a given axis will cause the model to rotate more quickly around that axis. In this way,
the Guardian 2D / 3D Stabilizer makes user-defined Dual (Expanded) Servo Rates unnecessary.
Issue: The Guardian does not move my servos when I move the model around.
Solutions:
• Make sure that the gain control knobs on the Guardian are not in the center (vertical) position, which disables stabilization
• If you are using a 3 position Mode/Config switch, make sure it is not set in the center (disabled) position.
• If you are using a Gain knob on your transmitter, make sure that it’s not turned to -100% servo deflection, which will disable
stabilization.
Issue: The Guardian moves my servos in the wrong direction as I move the model around.
Solution: The gain control knobs on the Guardian set the direction of stabilized servo movement, as well as the gain level.
Issue: Stabilization suddenly stops working or stabilizes incorrectly during flight, but resumes correct operation later.
Solutions:
• The Guardian may be experiencing brownout. See BEC/Receiver Battery Power Requirements section above.
• Make sure that the Guardian is securely mounted, and not “flapping around” during aggressive maneuvers
• If, during engine run-up, you notice the servos shifting or moving around inappropriately, you may need to move the Guardian
away from sources of RFI (such as a powerful BEC or motor). Or, you may need to mount the Guardian differently to reduce
excessive vibration.
Issue: Reset Level Flight doesn’t seem to work.
Solution: Make sure the Guardian is mounted approximately level. Mounting offsets in excess of 25 degrees can reduce performance
and will cause the Reset Level Flight to fail.
