Description

Overview

The R3115 900KV is a 36S brushless motor built around a 3115 mm stator and a lightweight 112 g bell/rotor assembly. Factory test data (10.5 prop, ~2522 V input) show smooth RPM growth to 14,650 RPM and up to ~1.50 kW electrical input. Its a solid choice for mid-to-large builds that need stable efficiency across the mid-throttle band.
