SAFE technology
 

Discover to Fly Successfully with SAFE® Technology
If this is your very first RC aircraft, Horizon Hobby-exclusive SAFE (Sensing Unit Helped Flight Envelope) innovation avoids over-control and crashing while likewise providing multiple flight modes to deliver more control and capabilities as your abilities progress:

Novice Mode

In this flight mode, the aircraft has pitch and bank angle limitations to avoid over-control that can lead to a loss of orientation and crashes. When the control sticks are released, the aircraft instantly returns to level flight by itself permitting you to unwind and enjoy simply 'steering' the aircraft through the sky. This flight mode likewise makes it easier to take off and land.

Beginner Mode
 

Intermediate Mode

This flight mode enables more flexibility in pitch and bank, but still avoids significant over-control and the aircraft does not return to level flight by itself. This enables you to make tighter turns and to climb up and come down quicker as your abilities advance. Likewise, Novice Mode instantly triggers and returns the aircraft to level flight when it comes down below roughly 30 feet above ground level and the control sticks are released.

Intermediate Mode
 

Knowledgeable Mode

In Knowledgeable 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 Healing can be activated by switching to Novice Mode and launching the control sticks.

Experienced Mode
 

 

Panic Healing

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

Panic Recovery

 

SAFE technology
 

Easily Update to SAFE® Plus GPS-Enabled Technology
With fast and simple installation of the optional Spektrum GPS Module you can include next-level autonomous guidance features that make it even easier to find out to fly. With SAFE Plus added you get:

AutoLand

Activated by simply holding down a button, the sophisticated AutoLand function puts the aircraft on a supported method to arrive on its own near the GPS initialization point. You can even provide some directional guidance to prevent challenges or to change the method while letting the system do the rest to carry out a safe landing. As your abilities progress and you get more self-confidence you can take control of more of the control inputs, eventually finding out to land with no assistance from the automatic system at all.

AutoLand
 

Holding Pattern

This very valuable SAFE Plus-exclusive feature essentially enables you to "pause" the flight by putting the aircraft into a GPS-guided holding pattern. When activated with the fast press of a button, the aircraft will instantly return to a position above the GPS initialization point and circle till the command is cancelled with another fast press of the button. It's a terrific way to safely hand the controls off to a pal or to gain back visual contact if you ever lose sight of the model.

Holding Pattern
 

Virtual Fence

It's simple to unintentionally let an RC aircraft fly too far away, but with Virtual Fence, fret no more. It produces an unnoticeable border the aircraft won't fly past. When the aircraft reaches this border, it will instantly reverse and fly back toward the GPS initialization point. Then it will "wag" the wings to let you understand when you have control again.
