2D Heading Hold Submode

With 2D Heading Hold submode, the Guardian will assert Aileron deflections to keep your model locked on its current 2D heading.

Whenever the control stick is moved to turn, this heading is reset and subsequently relocked as soon as the stick is centered again.

Automatic Turn Coordination

When enabled, Automatic Turn Coordination will cause the Guardian to employ the “step on the ball” method of actuating your Rudder

for you. As you enter a banked turn, the Guardian will work to coordinate your model for you. This mode is great for models that skid

easily.

3D Mode

In 3D Mode, the Guardian works to smooth out turbulence and stall characteristics to bring stability and precision to your model while

leaving the feel of flying the same as without stabilization. This mode is intended for more advanced pilots looking for improved stability

without compromising on performance and feel.

3D Heading Hold Submode

Centering the control stick in 3D Mode will engage 3D Heading Lock, which will cause your airplane to hold its present flight orientation

(assuming it is aerodynamically able to do so). In this mode, when the control stick is centered the Guardian remembers its current Pitch,

Roll and Heading and works to keep those locked. Moving the control stick immediately resets the locked heading, allowing for

instantaneous transitions from locked maneuvers to dynamic flight. Actuation of the Rudder control will reset just the Yaw axis, without

affecting the lock on Pitch and Roll.

Direct Rate 3D Control Submode

Unlike many other gyro stabilization systems, the Guardian employs Direct Rate 3D Control to translate your stick deflections to angular

rates without forcing you to “fight the gyro.” With this feature enabled, the Guardian interprets your stick deflections as commanded

angular rates and attempts to have your model follow those commands. This way, snap rolls and other high speed maneuvers are possible

without compromising on stabilization effects.

General Safety Precautions

In addition to other warnings and other precautions in this manual, the following should always be observed:

1) The Guardian is intended for recreational use only. Any other use is not supported.

2) Fly safely! Please refer to the American Model Association’s Safety Code at http://www.modelaircraft.org/files/105.PDF, or

the appropriate safety code for your country. Always obey the law when flying.

3) If you have never set up or operated an RC model before, you will need help from an experienced modeler. Local RC clubs are

great ways to meet experienced modelers, and receive the required training.

4) Never operate your model aircraft near or over buildings, power/telephone lines, or other obstacles. Never operate your model

aircraft near or over other people!

5) RC models and accessories are not toys, and should be kept away from children, without proper adult supervision.

6) Be sure to always fly conservatively and exercise common sense, especially while learning to use the Guardian.

Overview/Quick Start

First, read through the manual to get a “big picture” understanding of mounting, connection, configuration and operation of the Guardian.

Also, consider watching the Guardian tutorial video located at http://youtu.be/Rt8Y3Lxnv-0. While the Guardian has a wealth of

configurable features and options, getting in the air for most airframes requires minimal setup and configuration. At a minimum, the
