Overview

Flashhobby’s Mars M3115 900KV is a high-efficiency 31×15 stator class BLDC motor tuned for 9–10-inch long-range builds (e.g., CX10 / Rekon10 Pro / Pumpkin 10). It runs on 3–6S LiPo, uses a rigid 5 mm shaft, and supports 4×M3 prop mounting. Bench tests show up to 4061 g peak thrust and 1602.6 W input power with 10×5 props while keeping temperatures under control—ideal for endurance and speed-focused quads.

Key features

  • Strong 12N/14P architecture for high torque & smooth throttle

  • 3–6S wide voltage range for flexible gearing/props

  • 5 mm shaft & 4×M3 hub for secure 9–10″ prop fit

  • Low resistance (0.085 Ω) and balanced rotor for efficiency

  • Lightweight 110 g (incl. wires) for better AUW on 10″ builds
