Product overview
The BrotherHobby Tornado T7 4215 Motor X Class(CW) is a propulsion component for an X Class drone build. Its physical architecture combines a 12N14P configuration, a stator made from 0.2mm Kawasaki silicon steel and N52H arc rotor magnets. A hollow titanium alloy shaft forms part of the rotating assembly, with Japanese NMB 17X6X6 bearings specified. Both the base casing and bell cap carry the material designation AI 7075, defining the construction of these two housing components.
Installation interfaces comprise an M6 propeller adapter shaft thread and an M4 bolt pattern measuring 30X30mm. Electrical integration is specified for 6-12S LiPo batteries, with 14 AWG wires measuring 750mm long. The stated 260g weight includes 75cm SR wires, making that wiring configuration relevant to mass planning. The technical ratings are 380KV, 520KV, 680KV and 800KV; the selector additionally lists 260. This difference leaves the 260 option without a matching technical specification entry.
