4PCS PRO 4215-380kv Brushless Motor 6-12s Quadcopter Motor for 13-15¡¯¡¯Propeller,FPV Multicopter Drone Replacement,Thrust 7.1KG(15.6 lbs) for Drone Long Range RC Plane,Airplane,Hexcopters,Octocopters

【Unmatched Power & Efficiency】The 4215 motor features ultra-pure copper windings, a 0.2mm silicon steel stator, 200°C high-temperature enameled wire, multi-strand winding, and a vacuum-pressure impregnated (VPI) process for maximum insulation. It delivers rock-solid performance in harsh environments from -40°C to 80°C (-40°F to 176°F).
【Built Tougher to Last Longer】Constructed with a SUS420J2 precision-core 6mm shaft, 7075 aerospace-grade aluminum caps, N52SH arc magnets,a 14-pole 12-slot high-torque design, 17x6x6 bearings, the 4215 fpv motor shrugs off impacts, dissipates heat incredibly fast, and outlasts the competition.
【Ultra-lightweight Design】With a volume of 1.92"*2.56"(49*65mm), and a 12-slot stator of 1.26"*0.45"(42*15mm), Only 9.17ounces(263g,includes 14AWG 750mm SR wires). Designed to minimize weight while maximizing thrust and stability in flight,the thrust of a single 4215-380kv motor is as high as 7kg.Paired with 12/15/11 inch prop,4215 drone motor brings ultra-high explosive power.
【Quiet&Smooth Operation】New optimization adjustments and calibration, maintaining high torque at low speeds, linear power output when throttle changes rapidly, precise and fast response when turning, this 12S drone motor can provide stronger and smooth power for cinematic flights and heavy lift.
【Maintenance-Free&Reliadle】Easy to install,NO need for complex installation after purchase,it can be used. Great for heavy lift applications using propellers ranging from 13-15".This is a superior and user-friendly solution offers all multicopters and drones manufacturers, engineers, pilots and enthusiasts the best performance and reliability.
