With the new SAFE system proving itself to be a superb performer hobby zone have announced a new product which utilities this technology.

The all new Delta Ray, is modern take on a trainer. The Delta Ray is as the name suggests a delta aircraft with twin motors. You might think that’s not an ideal trainer, well actually for several reason it is! The twin motors rotate in separate directions thus cancelling out torque effect, this creates a stable aircraft at all throttle positions. The delta wing has a lot of area and with the tips swipe up the stability and stall characterises are great improved.

Add to these design factors the new SAFE system and the learning curve for new modellers is less steep, will reduce your financial risk and give you a more enjoyable experience! It looks great too!


With SAFE™ technology and carefully engineered aerodynamics, the groundbreaking HobbyZone® Delta Ray™ aircraft provide pilots with a flying experience that is gentle and worry-free, even for total beginners! Plus, everything you need comes in one box, including a Spektrum™ DX4e transmitter, making it the ultimate beginner-friendly aircraft.

Key Features

Intuitive SAFE™ technology provides four modes to give new pilots the ultimate progressive learning experience
If you lose control of the airplane, “Panic Mode” returns the aircraft to stable, level flight with the push of a button!
Beginner and Intermediate modes provide support for new pilots by limiting the roll and pitch of the airplane, keeping you in control at all times!

Some info and terms taken from SAFE webpage.

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® technologyThe 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 longitudinally (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.

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 connects the wings, nose and tail section together.

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 (Sensor Assisted Flight Envelope) 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; A servo transforms your command delivered by the transmitter to the receiver into physical movement of a control surface on 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 dedicated RC brand specializing in the development, refinement, testing and production of 2.4GHz spread spectrum systems including 2-way data (telemetry) transfer. Their current aircraft frequency protocol titles 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.ThrustThe forward aerodynamic force produced by a propeller, fan, or turbojet engine as it forces a mass of air to the rear, behind the aircraft.


(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 (measured in square inch and square decimeters for model aircraft), 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.
