Overview
Nearly everyone who sees a radio-controlled (RC) jet tear across the sky has the same reaction: "I want to fly one of those!" But because of their speed and handling challenges, RC jets have been almost impossible for first-time or low-time RC pilots to fly successfully — until now. Thanks to the E-flite Habu STS 70mm EDF jet, you can actually learn to fly RC aeroplanes successfully with a jet. The Habu STS 70mm EDF is based on the legendary Habu, one of the best high-performance Electric Ducted Fan (EDF) sport jet platforms ever created. E-flite engineers have optimised the design to improve its low-speed handling and slow speed performance and added options for taking advantage of exclusive Spektrum SAFE flight assistance technology. As a result, the Habu STS 70mm EDF is the easiest to fly RC jet ever, and the perfect choice to satisfy any RC pilot's desire to fly a jet. This Ready-to-Fly (RTF) Basic version is a complete, ready-to-run RC aircraft that includes everything needed to fly except for a compatible LiPo battery and charger, making it an excellent introduction to the world of RC jet flying for both new and experienced pilots.
The Habu STS 70mm EDF represents a breakthrough in RC jet accessibility. Unlike traditional jets that require advanced flying skills and experience, this Smart Trainer model features exclusive Spektrum SAFE (Sensor Assisted Flight Envelope) technology with multiple flight modes that adapt to your skill level. Whether you are completely new to RC flying or transitioning from prop-driven aircraft to jets, the Habu STS provides the perfect platform for learning. The Ready-to-Fly Basic package includes a Spektrum DXS DSMX 2.4GHz transmitter and factory-installed power system, meaning you can be ready to fly in less than an hour with just the addition of a suitable battery and charger. This makes it an ideal ready-to-run RC jet for enthusiasts in the UK looking to experience the thrill of electric jet flying without the complexity and cost of high-end competition models.
Built with durable EPO construction and equipped with a wide-stance tricycle landing gear featuring oversized tyres and a steerable nose wheel, the Habu STS can operate from various surfaces including paved runways, grass, and even dirt. The powerful brushless power system includes a telemetry-capable ESC and specially tuned motor with a 10-blade 70mm fan that delivers excellent performance on 3S batteries for everyday flying, or extra power and speed on 4S without any modifications. With quick, glue-free assembly and a full line of replacement parts available, this is a practical and reliable choice for anyone wanting to learn jet flying or expand their RC flying experience.
