A brief look at SAFE

An introduction to SAFE™ technology for RC aircraft.

ABOUT SAFE


Groundbreaking SAFE™ (Sensor Assisted Flight Envelope)
technology makes RC flight incredibly easy even for the least
experienced user. It revolutionary capability gives a model aircraft
spatial awareness making it possible to provide flight envelope
protection and a degree of security new pilots especially never had. Every pilot’s needs are
different, that’s why multiple levels of flight envelope protection are selectable through the
transmitter so that when flight conditions change, so can the level of protection. SAFE technology only
limits the attitude of the aircraft. It in no way interferes with the freedom of control within the limits chosen
by the pilot. In addition, SAFE technology makes smooth flight easier by battling windy conditions for you
so that you can focus on guiding the aircraft the way you want.

Best of all, sophisticated SAFE technology doesn’t require any work to enjoy. Every aircraft with SAFE installed is ready to use and optimised to offer the best possible flight experience.

SAFE FEATURES


  Aircraft with groundbreaking SAFE technology include exclusive features that make them more intelligent so you can enjoy RC flight more, regardless of your experience level.
Flight Envelope Protection Flight Envelope Protection
Multi-axis sensors combined with unique software create an intelligent aircraft that understands its position in the air relative to the horizon. This unique level of comprehension allows SAFE to keep the aircraft in a safe attitude without interfering with a pilot’s freedom of control.
Smoother Flight Capability Smoother Flight Capability
In addition to its complex levels of envelope protection, multi-axis stability keeps the aircraft flying rock solid even in windy conditions. The work load reduction improves confidence and significantly helps the aircraft handle cross-wind conditions so the pilot can better focus on aircraft position.
Multiple Modes Multiple Modes
From the transmitter, the pilot can select the level of flight envelope protection desired at any time. Each mode offers progressive performance so the pilot can naturally develop skills safely.

PROTECTION AND PERFORMANCE


The integration of SAFE™ technology into products introduces a sophisticated flight training system that allows RC pilots to develop flying skills more safely. This is not an autopilot or self-guiding robot. The sensors and software in this system help you fly the airplane by offering progressive modes of protection that significantly reduce the risk of an out-of-control crash. Regardless of the mode you choose, freedom of control within that envelope is unrestricted.
Beginner Mode Intermediate Mode Experienced Mode
BEGINNER MODE
Pitch and Roll angles are limited to help you keep the aircraft airborne

When controls are returned to neutral, SAFE returns aircraft to level flight

Stability assisted takeoff and landing

Throttle based climb and descent
INTERMEDIATE MODE
Pitch and Roll angle allowances are expanded to offer a larger flight envelope that protects the pilot from entering extreme flight conditions

The pilot experiences natural AS3X® technology assited flight for smooth handling and outstanding precision
EXPERIENCED MODE
The pilot experiences natural AS3X technology assisted flight for smooth handling and outstanding precision with a virtually unlimited flight envelope.
RECOVERY AT THE FLIP OF A SWITCH
Turn - @#$% - into
You can progress through each flight mode as your skills increase, all with the confidence of an optional Panic Recovery mode. At the flip of a transmitter switch any time during a flight, Panic recovery will get your aircraft to a safe flying attitude.


Point 1 Pilot loses control of the aircraft in any flight mode.
Point 2 Pilot pulls and holds the Panic Recovery switch and returns all other controls to their neutral position. The aircraft will roll wings level and pull out of a dive...
Point 3 ...once the aircraft is flying straight and level, the pilot releases the Panic Recovery switch and continues a gentle climb to a safe altitude.
Oh Yeah

SAFE FAQ's


SAFE GLOSSARY


Airplane
An engine-driven, fixed-wing aircraft heavier than air that is supported in flight by the dynamic reaction of air against its wings.

Ailerons
Found on the trailing edge of each wing, they work in opposite directions to bank (roll) the airplane about the longitudinal axis. To roll right, the right aileron is raised and the left aileron lowers.

ARF
An “Almost Ready to Fly” model is almost completely built and requires some assembly to complete when compared to a traditional kit that’s just basically raw materials.

AS3X® technology
The AS3X system for airplanes is an exclusive electronic and setup enhancement that combines multi-axis sensors and state-of-the-art software that helps make flight smoother and more stable. It is available in some RTF aircraft or as an add-on component a modeler can choose to improve the flight characteristics of their airplane.

Axis
The axes of an aircraft are three imaginary lines that pass through an aircraft’s center of gravity. The axes can be considered as imaginary axles around which the aircraft rotates. The three axes pass through the center of gravity at 90° angles to each other. The axis that extends nose through tail is called the longitudinal axis, and rotation about this axis is called roll. The axis that extends wingtip through wingtip is called the lateral axis, and rotation about this axis is called pitch. The axis that passes vertically is called the vertical axis, and rotation about this axis is called yaw.

Bank
A term used to describe the tilt of an aircraft laterally (roll) that occurs while turning. An angle of bank determines the rate of turn as well as the stability of the aircraft in that turn.

BNF
Bind-N-Fly® model aircraft, exclusive to Horizon Hobby, are almost ready to fly aircraft with the engine/motor system, DSM2/DSMX compatible receiver and servos preinstalled, but do not include the transmitter. They require minimal assembly to be flight ready, and when electric powered, also include the necessary flight battery.

Buddy Box
The setup of two transmitters, linked by cable, for the purpose of RC flight instruction. The instructor holds the primary transmitter and has authority to transfer control to the secondary transmitter in the hands of the student (buddy) or resume control instantly.


Center of Gravity (CG)
The point at which an airplane would balance if it were possible to suspend it at that point. It is the mass center of the airplane, or the theoretical point at which the entire weight of the airplane is assumed to be concentrated. The location depends on the distribution of weight in the airplane.

Control Surfaces
These are the moving portions of the wing, stabilizer and fin of an aircraft that are named aileron, elevator, and rudder controls respectively. These primary controls allow the pilot to roll (aileron), pitch (elevator) and yaw (rudder) the aircraft. Secondary controls include flaps and spoilers.

Drag
The net aerodynamic force parallel to the relative wind, usually the sum of two components: induced drag and parasitic drag.

DSM2® & DSMX®
Forms of 2.4GHz spread spectrum radio control language (protocols) that are proprietary to Spektrum™ aircraft transmitters and receivers used exclusively in Bind-N-Fly aircraft.

Dual Rates
A two or three-position switch on the transmitter which can be set to select different control throws for flight controls. They are used so that the pilot can increase or decrease the maneuverability of the aircraft in flight.

ESC
An “Electronic Speed Control” is a device connected between the electric motor, flight battery and receiver of an aircraft, which is used to convert the throttle commands from your transmitter into a motor speed rate.

Elevator
The horizontal, movable primary control surface in the tail section, or empennage, of an airplane. The elevator is hinged to the trailing edge of the fixed horizontal stabilizer and is the primary control for pointing the nose up or down about the lateral axis.

Fin
The vertical surface of the tail that gives the airplane stability while in flight. The yaw control surface connected to it is called the rudder.

Flaps
Hinged portion of the trailing edge between the ailerons and fuselage. In some aircraft, ailerons and flaps are interconnected to produce full-span “flaperons”. In either case, flaps change the lift and drag on the wing.


Flare
The point during landing in which the pilot reduces airspeed while raising the nose of the airplane with up elevator which further slows the descent of the aircraft and makes the touchdown as smooth as possible.

Flight Envelope
Ranges of maneuverability where limits of roll, pitch and yaw attitude are set in order to protect the stability of an aircraft.

Fuselage
The main section of the airplane that consists of the wings and stabilizing surfaces and the controls for the airplane.

Gimbal (or Stick)
The device that allows the user to input desired control movements into the transmitter.

Helicopter (rotorcraft)
An aircraft that derives its lift from blades that rotate about an approximately vertical central axis.

High Wing
This term describes an airplane that has its wing mounted on the top of the fuselage.

Landing Gear
The wheel assembly an aircraft uses to land and maneuver on the ground

Lift
A component of the total aerodynamic force on an airfoil and acts perpendicular to the relative wind.

Multiple modes (flight modes)
A switch selectable option on the aircraft transmitter that allows an RC pilot to change a variable amount of options at once, such as maneuverability and control feel.

Multicopter
A rotorcraft with more than two rotors. Multirotors often use fixed-pitch blades, whose rotor pitch does not vary as the blades rotate; control of vehicle motion is achieved by varying the relative speed of each rotor to change the thrust and torque produced by each.

Pitch
Motion of the aircraft about the lateral axis where the nose of the aircraft points up or down conventionally by moving the elevator on the tail.

Proportional
The ability to incrementally adjust aircraft control positions and input.

RTF
A “Ready-to-Fly” RC aircraft is sold with its electronics and power system pre-installed and can be assembled in a short amount of time. It also includes the required transmitter, plus the flight battery and charger if the model is electric.

Receiver
The receiver unit in the airplane receives the signals from your transmitter and passes your instructions along to the electronic devices connected to the controls.

Relative Airflow (also Relative Wind)
Direction of the airflow produced by an object moving through the air. The relative wind for an airplane in flight flows in a direction parallel with and opposite to the direction of flight; therefore, the actual flight path of the airplane determines the direction of the relative wind.

Rotor
An assembly of rotating airfoils, as that of a helicopter mounted horizontally to add lift, and on its tail mounted vertically to add rotational stability.

Rudder
The movable primary control surface mounted on the trailing edge of the vertical fin of an airplane. Movement of the rudder rotates the airplane about its vertical axis.

SAFE™ Technology
SAFE technology is a revolutionary electronic flight envelope protection system. It also offers smoother flight capability that battles windy conditions for you and multiple modes so you can fly with the level of protection and assistance that suits any given moment of the flight.

Sensor
An electronic device that responds to a physical stimulus and transmits a resulting impulse that can help identify condition status.

Servo
The servo transforms your transmitter commands into physical movement of the control surfaces of the aircraft.

Solo
Flying your aircraft unaided by an instructor.

Spatial awareness
The ability to be aware of oneself in space. Aircraft with SAFE technology use this awareness to help the RC pilot maintain control within a specific flight envelope. 


Spektrum
A 2.4GHz RC technology available for RC aircraft that ensures interference-free flight. Its current aircraft frequency protocols are DSM2 and DSMX.

Spinner
Cone that covers the propeller hub for appearance and/or streamlining purposes.

Stability
The inherent quality of an airplane to correct for conditions that may disturb its equilibrium, and to return or to continue on the original flightpath. It is primarily an airplane design characteristic.

Stabilizer
A fixed horizontal or vertical surface on the tail that gives the airplane stability while in flight. The horizontal surface is often referred to as the “stab” and the vertical stabilizer is popularly called the “fin”.

Stall
A rapid decrease in lift caused by the separation of airflow from the wing’s surface, brought on by exceeding the critical angle of attack. A stall can occur at any pitch attitude or airspeed.

Throttle
A control of the engine or electric motor that increases or decreases the speed of propulsion system and the amount of thrust produced.

Thrust
The forward aerodynamic force produced by a propeller, fan, or turbojet engine as it forces a mass of air to the rear, behind the aircraft.

Torque
(1) A resistance to turning or twisting. (2) Forces that produce a twisting or rotating motion. (3) In an airplane, the tendency of the aircraft to turn (roll) in the opposite direction of rotation of the engine and propeller. (4) In helicopters with a single, main rotor system, the tendency of the helicopter to turn in the opposite direction of the main rotor rotation.

Transmitter
This is the hand-held part of the radio system that transmits radio signals to the receiver in the aircraft.

Wings
Airfoils attached to each side of the fuselage and are the main lifting surfaces that support the airplane in flight.

Wing Area
The total surface of the wing (in square feet), which includes control surfaces and may include wing area covered by the fuselage (main body of the airplane), and engine nacelles.

Wing Chord
The chord of an airplane wing is the straight line distance from the leading edge of a wing to the trailing edge at a given point along its span.

Wing Span
The maximum distance from wingtip to wingtip.

Yaw
Rotation about the vertical axis, controlled by the rudder of an airplane. Moving the rudder left yaws the nose of the aircraft left, and vice versa.
