Tuning Guide

Spirit Tuning Guide

This guide should help you in tuning your helicopter to fit your flying style exactly.

First from all, you should try default settings that are recommended. There are basic parameters that you have to set first (for example in the wizard) but other are usefull so you can adjust stick feeling, flight behavior. Basically, you can set the behavior so that it is very similar to any known flybarless or flybared system.

If you are in the state that the helicopter is flying, but you need to do some corrections, you should start with the rudder settings first.

RUDDER TUNING

Prerequisite step: You can verify that the rudder servo limits are not too low or either not too high.

If the value is less than 70, than it is too low. That mean that servo precision vs mechanical gain is not good. You can fix the issue with putting ball link on the rudder servo horn closer to the center so that limit can be higher. In case the value is more than 170 there is mostly too high servo precision vs mechanical gain. You should put longer tail horn, so the ball linkage can be farther. Be sure you have configured limits that tail slider is moving from end to end, but without any mechanical binding (servo is buzzing). In case your tail mechanism allows blades pitch higher than 45°, do not set limits higher. It is not needed that limits for both sides are equal.
