Duet S 2 525mm RTF (HBZ05300)

Duet S 2 Ready-To-Fly is a compact, beginner-friendly RC trainer designed to teach the basics in small spaces. This ultra-micro airplane arrives 100% factory-assembled and ready to fly, with everything you need in the box—2.4GHz transmitter, AA batteries for the transmitter, a 1S LiPo battery, and a USB charger—so there’s nothing extra to buy or assemble. It includes exclusive SAFE technology that helps prevent overcontrol and loss of orientation, making it easier for new pilots to learn with confidence.

Three-channel control covers climb/descend, steering, and throttle, while twin electric motors deliver stable power and easy turning with differential thrust. The lightweight EPS foam airframe keeps the model durable for learning, and the built-in landing gear lets you take off and land on smooth surfaces; removing the gear enables hand launches or grass landings. Telemetry reports flight battery power to the transmitter, so it’s easy to monitor remaining charge, and replacement parts plus extra batteries are available separately for extended flying. No FAA registration is required for models under the 250-gram weight limit.
