B-Qtech S116 Brushless Drone — Dual 720P Cameras, 6‑Way Obstacle Avoidance, Optical Flow, 2×2000mAh Batteries, RC & App Control

High-performance brushless propulsion: Four high-torque brushless motors deliver wind-resistant flight up to 5m/s (11mph) and include improved heat-dissipation channels. These motors are 35% more efficient than coreless alternatives, giving stronger, more reliable flight. Intelligent obstacle sensing: A 6‑way infrared array (front/back/left/right/up/down) scans up to a 1.5m radius and automatically adjusts the aircraft’s path while preserving a stable 100m control range. Precision hover and stability: Downward optical flow sensors provide SmartVision hover with ±0.2m altitude locking, one-button takeoff/landing, and wind compensation that limits drift to under <0.3m even at 5m/s. Smooth live video and storage: Dual-band 2.4GHz/5GHz Wi‑Fi streams 720P video at 30fps to your smartphone with latency below <150ms; footage can be saved concurrently to the drone and a 64GB microSD card. Reliable power system: Two intelligent 2000mAh Li‑Po batteries deliver a combined 26 minutes of flight time (13 minutes per battery), support USB‑C fast charging (2hrs for a full charge), and include a five-layer protection scheme against overcharge and overdischarge. Remote control options: Operate with the included RC or via the smartphone app for flexible piloting and live monitoring.
