5.11 Configuring the Flight Controller/Stabilizer

The main steps involved in configuring and tuning the flight controller are:

 Setting the controller gains for initial flight

Confirming that the control surfaces are moving in the correct direction

Confirming ESC endpoints are correctly programmed

Setting idle throttle, and confirming motor order and rotation direction are correct

Configuring low battery autoland

 Setting flat level mounting, which lets the Vector compensate for small mounting offsets

 Rezeroing the gyros

5.11.1 Setting Controller Gains

5.11.1.1 Description of Controller Gains

If you are not familiar with some of the terms used below, please refer to the glossary at the start of the

manual, or consider searching for the terms on http://wikipedia.org.

The concept of controller stabilization gains can be hard to

understand, and many people (including many very

experienced pilots) have trouble grasping these concepts – you

are not alone! Fortunately, with the Vector, only a basic

knowledge of how gains work is required in most

circumstances.

Basic Gains

There are four main axes (or directions) that are controlled by

separate gains: pitch, roll, yaw, and altitude hold (vertical). The

gains that control these are referred to as “Basic Gains”.

The basic gains control how strongly the Vector responds to

perturbations (stick movements, air turbulence, etc.) in each

axis.

When you are in a 2D (model leveling) mode, basic gains control

how hard the controller will push your control surfaces (or

motors) to return to level flight, when your control stick is

centered.

If a gain value is too low, the Vector will not push your control

surface or motors hard enough to return to level quickly. For

example, with a fixed wing plane in 2D Mode, if the roll gain is
