Chapter 6
Tail Rotor Balance
(Revision 3, Oct 2012)
This section is intended to familiarize you with the various electronic chart forms and setup
screens used with the 4040 Viper. First by looking at each of the chart forms found in the tail
rotor section, then by using these forms to create an actual setup.
6.1. – Analyzer Chart Forms
Just as in the case with polar balance charts, there are two types of analyzer chart “forms”
used with the 4040 Viper. The chart forms are also categorized as either “Regular” or
“Irregular”. The selection of setup type is made within the chart form itself by using either the
[⇒] or [⇐] keys to toggle between “Regular” and “Irregular” in the “Chart Type” field, then
pressing the [⇓] key to move to the next field. The remaining fields in the screen will
automatically change if necessary. The paragraphs below describe these forms in detail.
6.1.1. – Regular Chart Forms
A “Regular” chart is one that has all weight positions spaced equally around the chart, all
adjustments are of the same type, and all adjustments carry the same ICF. The next paragraph
details the process for defining a tail rotor “Regular” chart setup.
