It is the motor included with the Firma 150 Amp ESC\/motor combo (SPMXSEMC05), making it a direct replacement for that system as well as a strong upgrade path for large-scale bashers and racers moving up in power.\u003c\/p\u003e\u003cp\u003eThe low-cog 4-pole, 8-magnet rotor design delivers smooth power delivery and precise throttle control even at low speeds, with the strong bottom-end torque that four-pole motors are known for. Construction is high quality throughout: a CNC-machined aluminum housing for heat dissipation, insulated high-purity copper windings for efficiency, precision ball bearings, and a hardened alloy steel output shaft.\u003c\/p\u003e\u003cp\u003eThe Safe-D shaft is a standout feature — it provides a C-clip locking point that mechanically prevents pinion gear slip under rapid acceleration and hard braking. Factory-installed 4mm gold-plated bullet connectors make installation plug-and-play, and the motor is perfectly matched to the Firma 150 Smart ESC.\u003c\/p\u003e\u003cp\u003eDealer fitment references include the ARRMA 6S BLX family: Kraton 6S, Big Rock 6S, Felony, Mojave 6S, Fireteam, Notorious, Infraction V2, and Typhon 6S. The package includes one brushless motor.\u003c\/p\u003e","brand":"Spektrum","offers":[{"title":"Default Title","offer_id":55716949524802,"sku":"SPMXSM1700","price":0.0,"currency_code":"USD","in_stock":false}],"url":"https:\/\/www.powerhobby.com\/products\/spektrum-spmxsm1700-firma-4074-2050kv-motor","provider":"PowerHobby","version":"1.0","type":"link"}
