The Blade BLH013050 Nano S3 BNF Basic builds on the popular Nano S2 with a fully re-tuned flight controller, improved AS3X stability, improved SAFE mode with angle demand, SAFE-Z altitude control, and built-in voltage telemetry to compatible Spektrum transmitters. The vertically mounted flight controller significantly improves gyro damping and vibration rejection for precise 3D control. Carbon fiber main shaft and tail boom keep the airframe light and durable. Most Nano S2 parts are compatible. Key Features Improved AS3X stability and SAFE mode with angle demand SAFE-Z altitude control via on-board accelerometer Improved Panic Recovery mode Built-in voltage telemetry to compatible Spektrum transmitters Vertically mounted flight controller for improved gyro damping 3 flight modes: Stability-Z, Stability, and Agility Linear servos for precise control authority Carbon fiber main shaft and tail boom Super-resilient polymer airframe Compatible with most Nano S2 replacement parts Skill Level 2 — transmitter, battery, and charger sold separately Three Flight Modes Stability-Z: Limited envelope with self-leveling, low bank angle limit, and software-dampened pitch control. Stability: Limited envelope with self-leveling and low bank angle limit. Agility: Full control authority with no bank angle limit. SAFE Technology Exclusive SAFE (Sensor Assisted Flight Envelope) technology lets you choose the right amount of assistance with the flip of a switch — from self-leveling stability to full 3D agility. Panic Recovery Mode Instantly recovers the heli to a level attitude to prevent crashes. Press the Panic Recovery button any time you lose orientation. SAFE-Z Altitude Control Keeps the heli at a consistent altitude via accelerometer programming — ideal for learning hovering and basic maneuvers. Integrated Telemetry Built-in voltage telemetry feeds real-time battery data to compatible Spektrum transmitters for smarter flight management. Durable Construction Super-resilient polymer airframe with carbon fiber main shaft and tail boom absorbs typical 3D practice impacts without damage.
