Learn to Fly Successfully with SAFE® Technology
If this is your first RC airplane, Horizon Hobby-exclusive SAFE (Sensor Assisted Flight Envelope) technology prevents over-control and crashing while also offering multiple flight modes to deliver more control and capabilities as your skills progress:
Beginner Mode
Pitch and bank angle limits prevent over-control that can result in a loss of orientation and crashes. When the control sticks are released the airplane returns to level flight on its own. Best of all takeoffs are as simple as giving full throttle and letting the airplane fly off the ground or by giving it a quick hand launch.
Intermediate Mode
More freedom in pitch and bank, but still prevents over-control and does not return to level flight on its own. This mode allows you to make tighter turns and to climb and descend faster as your skills advance. Beginner mode automatically activates and returns the airplane to level flight when the airplane descends below approximately 30 feet above ground level and the sticks are released.
Experienced Mode
No pitch or bank angle limits so you have complete control! You can even fly inverted (upside down) and perform aerobatic maneuvers including loops, rolls, stall turns and more. Panic Recovery Mode can be activated by switching to Beginner Mode and releasing the sticks.
Panic Recovery
If you ever lose control of the airplane in the more advanced control modes simply switch to Beginner Mode and release the control sticks. SAFE® technology will automatically return the airplane to level flight.

Technical Performance
The HobbyZone Duet S 2 delivers impressive performance in an ultra-micro package. Powered by two brushed electric motors with integrated electronic speed control, the aircraft uses a compact 1S 150mAh LiPo battery with a PH 1.5 (Ultra Micro) connector that provides enough power for exciting flights whilst keeping weight to just 43 grams. The lightweight airframe spans 525 millimetres from wingtip to wingtip and measures 368 millimetres from nose to tail, making it compact enough to transport easily whilst still providing stable, predictable handling characteristics that make it ideal for learning proper control inputs. The EPS foam construction provides an excellent balance between durability and weight, absorbing minor impacts and landing dings without permanent damage, and replacement parts are readily available should you need them. The aircraft is equipped with oversized tyres on its landing gear for easy handling on various surfaces, and the twin motors with differential thrust allow the pilot to control direction by varying the throttle to each motor independently, eliminating the need for a rudder whilst maintaining simple, intuitive control that beginners can quickly understand. The integrated receiver and servo control unit, combined with the Spektrum DXS transmitter featuring DSMX 2.4GHz technology, provides reliable, interference-free control across typical flying distances for this class of aircraft.

Frequently Asked Questions
- Is the HobbyZone Duet S 2 suitable for absolute beginners with no RC flying experience? — Yes, absolutely. This is a Skill Level 1 trainer aircraft specifically designed for first-time RC pilots. The SAFE technology actively prevents overcontrol and loss of orientation, automatically returning the aircraft to level flight in beginner mode when you release the control sticks. The three-channel operation is straightforward and intuitive, focusing on the essential controls of throttle, steering, and pitch without overwhelming complexity. Thousands of pilots have successfully learned to fly on this model or its predecessors.
- What battery does the Duet S 2 need and how long does it take to charge? — The aircraft requires a 1S 150mAh LiPo battery with a PH 1.5 (Ultra Micro) connector, which is included in the box. The USB charger supplied is designed for this battery specification. Charging time will depend on your USB power source; a standard USB wall adapter typically charges the battery in approximately 30-45 minutes, though the manual should specify the exact charging time for your specific charger.
- Can I fly the Duet S 2 indoors or do I need a large open space? — The ultra-micro size of the Duet S 2 makes it suitable for a variety of flying locations, including large gardens, small parks, sports fields, and even indoors over a basketball court on a calm day. Its lightweight construction and gentle handling characteristics make it forgiving in confined spaces, though you should always ensure you have adequate clearance and that indoor flying is permitted at your chosen location.
- What makes the Duet S 2 different from other beginner RC trainers? — The Duet S 2 combines several advantages: it features exclusive SAFE technology with multiple flight modes, arrives completely ready to fly with no assembly required, includes everything you need in the box, weighs under 250 grams (no FAA registration), uses easily obtainable standard LiPo batteries, and represents one of the lowest-cost entry points into hobby-quality RC flight. The twin-motor configuration with differential thrust is simpler than traditional rudder-and-elevator aircraft, making it more intuitive for beginners.

Everything required to fly is included: the fully assembled airframe, motors, transmitter, receiver, battery, charger, and transmitter batteries. You need to buy absolutely nothing else to start flying—just charge the battery and you're ready for takeoff.
- Can I upgrade the battery for longer flight times? — Yes, the aircraft uses standard 1S LiPo batteries with a PH 1.5 connector, so you can purchase additional or higher-capacity batteries (such as 210mAh or 350mAh) separately to extend your flying time. Extra batteries and replacement parts are readily available from RC retailers specialising in Horizon Hobby products.
- What do the different flight modes do? — Beginner mode limits pitch and bank angles and automatically returns the aircraft to level flight when sticks are released, making it nearly impossible to crash from overcontrol. Intermediate mode provides more freedom whilst still preventing over-control and is useful as you develop your skills. Experienced mode removes all limits, allowing full aerobatic capability including loops, rolls, and inverted flight. Panic Recovery instantly switches you to beginner mode to recover from loss of control.
