S1 RC 3D Stunt Helicopter for Adults — RTF Dual Direct-Drive Brushless, Carbon Fiber Frame, GTS Flight Controller & App/Bluetooth Control

Designed for aggressive 3D flying, the S1 pairs twin direct-drive brushless motors with a lightweight carbon fiber frame to deliver agile, stable performance. The upgraded GTS flight controller works with a Bluetooth module and companion mobile app so you can fine-tune flight rates, curves and gyro settings from your phone for precise, smooth handling. This Ready-to-Fly (RTF) package includes Transmitter (Mode 1 Right-Hand), charger, batteries and tools. Setup is quick thanks to tool-free battery swaps, pre-adjusted linkages and simplified assembly, making it accessible for beginners and hobbyists alike. It supports popular radio systems with S-BUS, PPM and DSM-X protocol compatibility for easy expansion. Built for durability, the airframe uses all-metal gear digital servos, a high-strength aluminum tail boom and a one-piece nylon landing skid. Flight endurance is approx. 8-minute flights with the included dual 7.4V 300mAh batteries.
