Brushed Motor 21T & 80A ESC Combo for 1/10 RC Truck

The Product Description highlights the high performance and power of this offering. The 550-size motor features a 30% longer armature than a standard 540-size motor, resulting in extreme monster torque. Unlike other 550 Motor & 60A ESC Combos on the market, this product utilizes an 80A ESC to better address the overcurrent and overload issues often encountered with 60A ESCs.

Regarding the Motor Specifications, this 21-turn, 550-size motor produces 40-91W of power and is compatible with 7.4V (2S LiPo) or 6V-8.4V (5-7 cell NiMH) power sources. Its maximum current is 70A, and it can reach up to 22,500 RPM. The motor is waterproof to IP65 standards and measures 36mm in diameter and 55mm in length, with a 16mm extended shaft diameter of 3.175mm.

The ESC Specifications detail a Brushed 80A unit that is also waterproof to IP65 standards. It can handle a persistent current of 80A and a peak current of 320A in the forward direction, and 40A persistent/160A peak in reverse. The voltage range is 7.4V (2S LiPo) or 6V-8.4V (5-7 cell NiMH). The BEC output is a 5A 7.4V/6.4V adjustable Switch Mode. The ESC supports Crawler and High-Speed Adjustable (Forward/Reverse) running modes and can be programmed via its Program Port Jumper Cap. The dimensions are 42x35x27mm, and the weight is 50g.

The Packing List includes the Brushed 80A ESC, the 21T 550 motor, a Cooling Fan, and an XT60 to T Plugs Adapter Connector. The ESC offers multiple protections, including low voltage cut-off, over-heat, and throttle signal loss. Note that only 2S LiPo batteries can be used, not 3S.

The key highlights of this product are its superior materials, high performance, and the included extra cooling fan. The 550 21T brushed motor is made with premium quality materials and high-strength magnets for better and more stable performance, ensuring a long service life. The powerful motor's 30% longer armature, combined with the 80A ESC, provides extreme monster torque and addresses the overcurrent and overload issues common with 60A ESCs. Additionally, the included heatsink cooling fan helps solve the overheat problem of the motor.

This product is compatible with a wide range of 1/10 scale RC Off-Road Cars, including TRAXXAS TRX4, TRX6, TRX4 Bronco Pro, Axial SCX10, SCX10II, AXI03007, JL 90046, and RC4WD D90 models.
