SAFE technology
 

Learn to Fly Successfully with SAFE® Technology
If this is your first RC aircraft, Horizon Hobby-exclusive SAFE (Sensor Assisted Flight Envelope) technology avoids over-control and crashing while likewise using several flight modes to provide more control and capabilities as your skills development:

Novice Mode

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

Beginner Mode
 

Intermediate Mode

This flight mode permits more liberty in pitch and bank, but still avoids substantial over-control and the aircraft does not return to level flight on its own. This permits you to make tighter turns and to climb and come down quicker as your skills advance. Likewise, Novice Mode instantly triggers and returns the aircraft to level flight when it comes down below approximately 30 feet above ground level and the control sticks are launched.

Intermediate Mode
 

Skilled Mode

In Skilled Mode there are no pitch or bank angle limits so you have complete control! You can even fly inverted (upside down) and perform aerobatic maneuvers consisting of loops, rolls, stall turns and more. Panic Recovery can be triggered by changing to Novice Mode and releasing the control sticks.

Experienced Mode
 

 

Panic Recovery

If you lose control of the aircraft in the Intermediate or Skilled flight modes, simply switch to Novice Mode and launch the control sticks. SAFE technology will instantly return the aircraft to level flight.

Panic Recovery

 

SAFE technology
 

Quickly Update to SAFE® Plus GPS-Enabled Technology
With quick and easy setup of the optional Spektrum GPS Module you can include next-level autonomous guidance features that make it even easier to learn to fly. With SAFE Plus added you get:

AutoLand

Triggered by simply holding down a button, the sophisticated AutoLand function puts the aircraft on a supported technique to arrive on its own near the GPS initialization point. You can even provide some directional guidance to avoid barriers or to adjust the technique while letting the system do the rest to perform a safe landing. As your skills development and you get more confidence you can take over more of the control inputs, eventually finding out to land with no support from the automated system at all.

AutoLand
 

Holding Pattern

This extremely useful SAFE Plus-exclusive feature essentially permits you to "stop briefly" the flight by putting the aircraft into a GPS-guided holding pattern. When triggered with the quick press of a button, the aircraft will instantly return to a position above the GPS initialization point and circle up until the command is cancelled with another quick press of the button. It's an excellent way to safely hand the controls off to a pal or to regain visual contact if you ever lose sight of the design.

Holding Pattern
 

Virtual Fence

It's easy to inadvertently let an RC aircraft fly too far away, but with Virtual Fence, stress no more. It develops an undetectable border the aircraft will not fly past. When the aircraft reaches this border, it will instantly reverse and fly back towards the GPS initialization point. Then it will "wag" the wings to let you understand when you have control again.
