Thank you for your purchase! Based on Eagle Tree's proven inertial stabilization technology, the Guardian 2D/3D Stabilizer (the Guardian) stabilizes most types of fixed
wing models, and works with most any radio. Unlike most “gyro stabilizer” products on the market, when configured correctly the Guardian provides true wing leveling
stabilization as well as precise fly-by-wire control. This lets you configure the Guardian to return to level flight in an emergency, by just flipping a radio switch!

Helpful Note

Pitch – Lift or descent of the nose and tail of the model. Normally controlled by the elevator, or
