Product overview
The BrotherHobby Nipple 3520 is a motor for fixed-wing propulsion. Its physical architecture combines a 20mm stator, a SUS420 shaft and N52H arc rotor magnets in a 12N14P configuration. The base casing and bell cap are both Al 7075. The motor weighs 189g, and its bearing specification is Φ14*Φ8*4. It is a propulsion component, with an electrical specification of 6S LiPo.
Mechanical integration uses the specified bolt patterns of M3 (25X25mm) and M4 (46.4-50X46.4-50mm). The motor wiring is 16# AWG with a length of 100mm.
