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 (Smart Trainer with SAFE) 70mm EDF jet, you can learn to fly RC airplanes 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 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 created, and the perfect choice to satisfy any RC pilot's desire to fly a jet. This Ready-To-Fly (RTF) Basic version includes everything needed to fly in one box except for a battery and charger. The powerful brushless power system including a telemetry-capable ESC and the servos are all factory-installed. The included Spektrum DXS 2.4GHz transmitter can be used with other Bind-N-Fly (BNF) and BNF Basic aircraft after you learn to fly the Habu STS successfully. In the Experienced Mode, the Habu STS 70mm EDF is capable of performing aerobatic maneuvers including loops, rolls, inverted flight and more. You can use a 3S 3200mAh to 4000mAh battery for an excellent balance of power and flight time, or you can install a compatible 4S battery for more speed and thrust without the need for any modifications or upgrades.
