SAFE technology
 

Learn to Fly Effectively with SAFE® Technology
If this is your very first RC plane, Horizon Hobby-exclusive SAFE (Sensor Assisted Flight Envelope) innovation prevents over-control and crashing while likewise offering numerous flight modes to provide more control and abilities as your skills development:

Novice Mode

In this flight mode, the plane has pitch and bank angle limitations to prevent over-control that can result in a loss of orientation and crashes. When the control sticks are launched, the plane instantly goes back to level flight on its own allowing you to relax and take pleasure in simply 'guiding' the plane through the sky. This flight mode likewise makes it simpler to take off and land.

Beginner Mode
 

Intermediate Mode

This flight mode enables more liberty in pitch and bank, but still prevents considerable over-control and the plane does not return to level flight on its own. This enables you to make tighter turns and to climb and descend quicker as your skills advance. Also, Novice Mode instantly activates and returns the plane to level flight when it comes down below around 30 feet above ground level and the control sticks are launched.

Intermediate Mode
 

Experienced Mode

In Experienced Mode there are no pitch or bank angle limitations so you have total control! You can even fly inverted (upside down) and carry out aerobatic maneuvers including loops, rolls, stall turns and more. Panic Recovery can be activated by switching to Novice Mode and launching the control sticks.

Experienced Mode
 

 

Panic Recovery

If you lose control of the plane in the Intermediate or Experienced flight modes, simply change to Novice Mode and launch the control sticks. SAFE innovation will instantly return the plane to level flight.

Panic Recovery

 

SAFE technology
 

Easily Update to SAFE® Plus GPS-Enabled Technology
With quick and easy installation of the optional Spektrum GPS Module you can add next-level autonomous assistance features that make it even simpler to find out to fly. With SAFE Plus added you get:

AutoLand

Activated by simply holding down a button, the innovative AutoLand function puts the plane on a stabilized technique to arrive on its own near the GPS initialization point. You can even provide some directional assistance to avoid obstacles or to adjust the technique while letting the system do the rest to carry out a safe landing. As your skills development and you get more self-confidence you can take control of more of the control inputs, ultimately finding out to land without any assistance from the automatic system at all.

AutoLand
 

Holding Pattern

This very practical SAFE Plus-exclusive function basically enables you to "pause" the flight by putting the plane into a GPS-guided holding pattern. When activated with the quick press of a button, the plane will instantly return to a position above the GPS initialization point and circle until the command is cancelled with another quick press of the button. It's a great way to securely hand the controls off to a friend or to restore visual contact if you ever lose sight of the model.

Holding Pattern
 

Virtual Fence

It's easy to inadvertently let an RC plane fly too far, but with Virtual Fence, stress no more. It produces an undetectable border the plane won't fly past. When the plane reaches this border, it will instantly turn around and fly back toward the GPS initialization point. Then it will "wag" the wings to let you know when you have control again.
