4.Vibration Analysis

Kevin Guest edited this page Dec 26, 2015 · 6 revisions

A big part of setting up any model is checking that the vibrations are within the limits set by the APM: Copter developers.

The APM Log File Analyser can be used to understand the level of vibrations of your given UAV.

From version 2.2 of the APM Log File Analyser vibration can be reviewed using the Graph.

X & Y vibrations should be within the limits of + - 3, certainly when hovering. However, when flying they maybe slightly higher. Z vibration should be within the limits of -5 to -15, certainly when hovering. Again, when flying this maybe slightly higher.

Here is an example of a well tuned UAV.
