Product overview
The GEPRC GR1204 3750KV Motors product supplies a brushless motor for Whoop and Toothpick drone builds, with an application range of 105mm-110mm RC drones. Its physical architecture combines a 9N12P configuration, a 12mm-diameter stator with 4mm length, N52H arc rotor magnets and a 7075-T6 base casing. A dual bearing design supports the rotating assembly. The motor weighs 3.8g, measures Φ15.28 × 10.9mm in diameter and length, and has a Φ1.5mm shaft for integration into the propulsion assembly.
Integration specifications include 40mm-75mm propellers and a 3750KV motor rating. The battery information contains two different ranges: the configuration-specific cell specification gives 3750KV at 3-4S LiPo, while the feature listing states compatibility with 1-4S LiPo batteries. That difference leaves the lower cell-count applicability unresolved. The supplied configuration is one motor with four each of M3x4, M3x5 and M3x7 button head screws. An additional dimensions entry gives 60 × 60 × 40 mm.
