BL2852 4500KV Brushless Motor 3.175mm & Brushless ESC for 1/12/14/16 RC

The GOUPRC BL2852 4500KV brushless motor and 45A ESC combo offers an all-in-one power upgrade for hobbyists running smaller RC vehicles. Designed for models ranging from 1/12 down to 1/16 scale (with some 1/10 applications noted), this pair targets off-road monster trucks, drift cars, and flat-track speed builds that need an efficient electrical powertrain.

At the center of the setup is a 4-pole, 12-slot motor featuring high-purity copper windings and a precision balanced rotor. This construction is geared toward maximum energy conversion, reliable high RPMs, and strong torque delivery. To match the output, the included speed controller handles 45A continuous current with a 480A peak capacity, backed by a 5V, 3A BEC capable of powering demanding steering servos.

Wiring options are flexible right out of the box, as the electronics work with both T-plug and XT60 lithium battery connections running 2S to 3S LiPo configurations. Both the motor and ESC are listed as easily programmable, allowing hobbyists to adjust drive settings to match their specific chassis and track conditions.

A notable trade-off is the ambiguous scale fitment in the specifications, which mention 1/12, 1/14, and 1/16 vehicles in some notes alongside 1/10 scale in others, requiring buyers to carefully verify motor dimensions against their vehicle. Additionally, while programmable, the package only contains the single motor and ESC without dedicated programming accessories.

Verdict: This combo is a strong choice for RC hobbyists seeking a high-KV brushless motor and matching 45A ESC for 2S or 3S small-scale builds. It provides the necessary power delivery and servo support for fast drift and track applications.

A great fit if you:

• Need a matched 4500KV motor and 45A speed controller for a 1/12, 1/14, or 1/16 scale RC chassis
• Run 2S or 3S LiPo batteries fitted with standard T-plug or XT60 connectors
• Require a built-in 5V 3A BEC to power a high-torque steering servo
• Build or upgrade vehicles for high-speed drift, flat-track, or off-road running

Consider something else if you:

• Require a power system intended for 4S or higher voltage battery setups
• Need a guaranteed direct drop-in fit for larger, heavy 1/8 scale RC platforms

What batteries work with this combo?
The system is compatible with 2S LiPo and 3S LiPo lithium batteries using either T-plug or XT60 connectors.

What is included in the package?
The package comes with one 45A brushless ESC and one brushless motor.

What is the output of the built-in BEC?
The ESC features a built-in BEC rated at 5V and 3A to support high-torque servos.

What types of RC vehicles is this motor designed for?
It is designed for 1/12, 1/14, and 1/16 scale off-road monster trucks, flat track models, and drift cars, as well as 1/10 to 1/12 scale RC cars.
