The HobbyZone Sport Cub S 2 is based on one of the most popular training aircraft ever developed for learning to fly radio-controlled (RC) aircraft - the legendary Sport Cub S. Its ultra-small size makes it the ideal choice for a smaller training model that can be flown in large yards, parks, baseball fields and other suitable areas where larger models cannot normally be flown successfully by beginners. The exclusive Safe (Sensor Assisted Flight Envelope) technology helps prevent over-control, loss of orientation and crashes, so almost anyone can learn to fly successfully! The 100% factory-assembled airframe is equipped with a reliable electric motor as well as an ESC (Electronic Speed Control) and receiver unit and four servos. The RTF version also comes with everything else needed to fly, including a battery, a charger and a controller/transmitter equipped with a USB-C port for direct connection to a PC for easy plug-and-play use of the included trial version of the RealFlight Trainer Edition RC flight simulator.
