Product overview
The BrotherHobby TC 1404 Ultralight Motor is a TC Series motor for FPV drones, with KV options of 2750, 3800 and 4600 and a specified battery configuration of 4-6S LiPo. Its electromagnetic architecture uses a 9N12P configuration, N52H arc rotor magnets and a stator made from 0.15mm Nippon silicon steel. The mechanical assembly combines a SUS 420 shaft with NSK 5x2x2.5 bearings, while the bell cap and base casing are both made from 7075 aluminum.
The motor’s mounting interface has an M2 9X9 bolt pattern, and its propeller adapter shaft thread is M 1.5. Its wiring is specified as 30 AWG with a 10cm length. The stated weight is 8.6g with 100mm length SR wires, making that wire configuration part of the weight specification. These physical details accompany the three KV options and the 4-6S LiPo specification for this FPV drone motor.
