Engineered as a direct drop-in upgrade to replace slow stock setups, this 4370KV Brushless Motor and 45A ESC combo is built around a 4-pole 12-slot high-torque rotor packed inside a finned 6061-T6 aluminum heatsink can. Delivering 820W of output with exceptional heat dissipation, its high-purity copper windings and high-precision ABEC5 bearings ensure smooth power delivery up to 48,000 RPM with minimal friction and noise.\u003c\/p\u003e\n\u003cp\u003ePaired with a waterproof 45A ESC equipped with a cooling fan and built-in 5.8V\/3A SBEC, this combo provides reliable throttle control, low-voltage protection, and plug-and-play convenience. The 5.8V high-voltage BEC delivers extra power to unlock better response and torque from your steering servo. This power system offers the ideal balance of torque, durability, and raw speed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e This motor fits standard 1\/10 scale RC cars designed for 3650-sized motors, but it is tuned for lighter setups. Due to its high KV rating, it is ideal for 1\/12 scale vehicles and lightweight 2WD 1\/10 cars, buggies, or road cars. It is not recommended for heavy 1\/10 4WD off-road monster trucks or short-course trucks.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBest Suited For:\u003c\/strong\u003e Hobbyists looking for a simple brushed-to-brushless upgrade, intermediate bashers, and kit builders wanting a budget-friendly power system that still delivers high performance.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e820W High-Torque Performance:\u003c\/strong\u003e 4-pole 12-slot design provides intense acceleration and continuous power for 1\/10 and 1\/12 scale models.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium Heat Management:\u003c\/strong\u003e Features a finned 6061-T6 billet aluminum heatsink body and high-temperature copper windings (rated up to 180–200°C).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Dynamically Balanced Rotor:\u003c\/strong\u003e Explosion-proof rotor balanced to within 10mg ensures silky-smooth operation at ultra-high RPMs; fully removable and replaceable.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWaterproof 45A ESC with SBEC:\u003c\/strong\u003e Includes an integrated cooling fan, a 5.8V\/3A BEC to boost steering servo performance, and pre-soldered T-plug (Deans) \u0026amp; 4.0mm bullet connectors.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ch3\u003eF540 Brushless Motor\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Surpass Hobby\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e F540 (Fin-cooled 3650-size housing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKV (RPM\/V):\u003c\/strong\u003e 4370KV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor Design:\u003c\/strong\u003e 4-Pole \/ 12-Slot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Power:\u003c\/strong\u003e 820W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Current:\u003c\/strong\u003e 66A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Voltage:\u003c\/strong\u003e 7.4V (2S) – 11.1V (3S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter:\u003c\/strong\u003e 36 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Diameter:\u003c\/strong\u003e 3.175 mm (1\/8\")\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Length:\u003c\/strong\u003e 15 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Screws:\u003c\/strong\u003e M3 multi-mount pattern\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearings:\u003c\/strong\u003e High-RPM ABEC5 Sealed Bearings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Connector:\u003c\/strong\u003e 4.0 mm Gold Bullet Plugs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 146 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e45A Electronic Speed Controller (ESC)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current:\u003c\/strong\u003e 45A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBurst Current:\u003c\/strong\u003e 260A (10 sec)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Voltage:\u003c\/strong\u003e 2–3S LiPo \/ 4–9 Cell NiMH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBEC Output:\u003c\/strong\u003e SBEC 5.8V \/ 3A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Connector:\u003c\/strong\u003e T-Plug (Deans Male)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Connectors:\u003c\/strong\u003e 4.0 mm Female Bullet Plugs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 45 x 35 x 35 mm (including fan)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 76 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Surpass Hobby F540 4370KV Brushless Motor\u003c\/li\u003e\n\u003cli\u003e1 x Waterproof 45A Brushless ESC (with integrated cooling fan \u0026amp; power switch)\u003c\/li\u003e\n\u003cli\u003e1 x Product Instruction Manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eNotes \u0026amp; Warnings\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequired to run (Not Included):\u003c\/strong\u003e 2S or 3S LiPo battery with a T-Plug connector, plus a pinion gear with a 3.175mm (1\/8\") bore diameter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3S LiPo Gearing Caution:\u003c\/strong\u003e When running on a 3S LiPo (11.1V), this 4370KV motor will approach ~48,000 RPM.
