STEP 7: FLIGHT TUNING
Now that the programming and setup for the mount stabilization modules is complete, it is time for inflight
tuning. After setting the gain on the bench, it is important to do some test flights to observe the operation of
the stabilization system in the air. It can be helpful to tune one axis at a time.
PAN AXIS:
For in-flight tuning, start with the pan axis. To test the pan module, yaw the multi-rotor and observe the 3-axis gimbal.
The gimbal should smoothly stabilize and stay on its original heading regardless of what is done with the multi-rotor
above it. Please be careful at first when using pan stabilization, as it can be very confusing for the pilot to observe the
multi-rotor spinning above a stationary camera gimbal. It is a good idea to learn to only look at the multi-rotor for visual
flight cues and not the gimbal. Once you turn on the stabilization / slewing on the 3-axis gimbal, the pilot and camera
operator will be de-coupled and the camera operator and pilot can operate completely independently.
ROLL AXIS:
With the pan axis tuned properly, we can move on to the roll axis. For roll axis, ensure that the camera is perfectly
balanced. We want to be able to move the camera to any roll angle setting and have it stay at that setting without the
tendency to swing back to neutral. Once the roll axis gain has been roughly tuned, we can do a test flight and observe
the roll axis behavior. Over gain will often show as small twitches. If you see any of these symptoms, please lower the
gain and test again. The proper gain setting will allow for fast and smooth stabilization with minimal twitches.
TILT AXIS:
Tuning the tilt axis will largely depend on the length and inertia of the camera you are using. After setting an initial gain
on the bench, do a test flight to ensure you do not have any over gain symptoms such as oscillations. After finding the
setting that allows for smooth and fast stabilization, your 3-axis gimbal will be setup and ready for use. Please note that
while the control algorithm on the stabilization system is quite robust, drastic changes to camera mass and balance
(lens changes, etc.) may require further fine tuning of the system.
