WUQ 3650 3900KV 60A Brushless Motor ESC Combo Toy

SKU CH-DKQE-SK4PW

A 3900KV brushless motor and 60A ESC combo for 1/10 scale RC vehicles, delivering 900W with a 69A max current rating

  • TypeModels & Kits
  • High-torque 4-pole 12-slot design masters 1/10 scale terrain
  • CNC 6061 T6 aluminium heatsink dissipates heat during hard runs
  • High-purity copper windings and balanced rotor maximise 900W efficiency
  • Pre-matched 3900KV motor with 60A ESC ensures plug-and-play compatibility
  • 69A peak current and 50000 RPM ceiling deliver explosive acceleration

1/10 Scale Brushless Power System

The WUQ 3650 combo pairs a 3900KV brushless motor with a matching 60A electronic speed controller. Designed for 1/10 scale RC cars and trucks, the set delivers 900 W of power and a maximum current draw of 69 A. The motor uses a 4-pole 12-slot high-torque layout and precision-balanced rotor for smooth operation at up to 50000 RPM. A CNC-machined 6061 T6 aluminum heatsink handles heat during extended runs.

Suited for single-motor 1/10 chassis

This combo fits builders upgrading a 1/10 scale truck or buggy who want a matched motor and ESC without separate selection. It is not intended for larger scale vehicles that require bigger can diameters or higher voltage capability. Drivers needing a sensored system for low-speed crawling control should look at other options. Multi-motor configurations such as 4WD twin-motor setups are also outside the scope of this single-unit package.

3900KV rating sets the speed envelope

The 3900KV constant means the motor spins 3900 RPM per applied volt, reaching 50000 RPM at the top of its range. This figure decides whether the gearing and battery voltage you plan to use will produce the target wheel speed without exceeding the 69 A current limit or overheating the 36 mm by 50 mm can. Match the KV to your cell count and pinion choice before purchase.

Questions about this item

Should I pick the 3900KV motor or a different KV for my 1/10 scale truck?

The 3900KV rating suits 2S LiPo packs in 1/10 scale cars and trucks, delivering up to 50000 RPM with strong low-end torque from the 4-pole 12-slot design.

What does the 900W rating mean when the combo is installed in my RC car?

It indicates the motor can draw up to 69A peak at 900W, so the 60A ESC will handle typical running loads while the aluminium heatsink keeps temperatures down during hard acceleration.

Does the 60A ESC limit the 69A peak current the motor can draw?

The ESC is rated for 60A continuous; the motor's 69A maximum occurs only in brief bursts, so the combo is matched for reliable operation without thermal shutdown.
