KO Propo Vfs-Fr3 Pro Brushed ESC

Introducing the KO PROPO VFS-FR3 PRO Brushed Speed Control.

This premium package features the Ultimate Booster 2 and Ultimate Capacitor—the gold-standard upgrades for the VFS-FR3.

While using the Ultimate Booster 2 (a high-performance Schottky diode for brushed motors) with a reverse-function ESC typically requires complex, specialized wiring, we have pre-installed this custom configuration at the factory. This eliminates the risk of wiring errors and ensures worry-free operation right out of the box. Combined with the Ultimate Condenser 35V for an extra tier of power, you can enjoy peak performance without the need for any soldering.

Benefits of the Ultimate Booster 2
The Ultimate Booster 2 manages "back-EMF" (electromotive force) generated by the motor with extreme efficiency. By minimizing electrical loss, it enables the motor to spin more smoothly, significantly improving RPM stretch and top-end speed.

Benefits of the Ultimate Condenser 35V
When pinning the throttle out of a corner, battery power delivery can sometimes lag behind demand. The Ultimate Condenser 35V acts as an instantaneous power reservoir to fill that gap. By supplying massive current the moment you need it, it provides a stronger "kick" from a standstill and slashes the time it takes to reach full speed on the straights.

Exclusive PRO Spec: Black Heat Sink
While the standard model features a silver heat sink, the VFS-FR3 PRO comes equipped with an exclusive Black Heat Sink.

An Easy-to-Use ESC for Beginners and Veterans Alike
A simple, ready-to-use design that allows you to install it right out of the box. It comes with preset programs that are compatible with any car. Additionally, motor connections are made easy with connectors, ensuring a hassle-free setup. Just follow the manual for initial setup, and you'll be ready to drive in no time.

Equipped with a Low Voltage Cutoff Function!
Lithium Polymer and Lithium Ferrite batteries can be damaged by over-discharge, but the VFS-FR3 is equipped with a low voltage cutoff function, allowing you to play without worrying about over-discharge. In the past, a PC was required to change the settings, but now with the VFS-FR3, you can select the battery mode during the initial ESC setup. You can also check which battery mode is selected by the LED status.

Available modes: Lipo/LiFe/NiMH, NiCD

Back Timer Setting Function Added
You can now set the time delay before entering reverse after pulling the trigger on the transmitter. This feature helps prevent accidental reversing during fine brake control, similar to pumping the brakes. During the initial ESC setup, you can choose from three levels. Additionally, more detailed settings can be adjusted using the manager software.

Compatible with KOPROPO's proprietary HCS
Now compatible with KOPROPO's proprietary "HCS" system, reducing the communication processing time between the receiver and ESC by 1/4 for a more direct control feel.

The mode automatically switches when connected to an HCS-compatible receiver. Of course, it can still be used in normal mode, so no changes are needed from previous compatible models.

Powerful BEC Circuit for Safe Use with Two Servos!
Equipped with a 6V 3A BEC circuit (receiver/servo power circuit), the VFS-FR3 uses high-capacity components, unlike the 1.5A parallel elements often found in overseas products. This ensures that even when using two high-current servos for 4WS systems, the circuit will not be damaged. Additionally, the built-in limiter function activates in the event of issues like steering lock, so you can use it with peace of mind.

Suitable for Experienced Drivers!
While you may start with the standard motor from the kit, as you gain experience, you'll want to push for more speed. The VFS-FR3 has no motor turn limit, so when you're ready to unleash even more performance, you can adjust the drive frequency to maximize the potential of high-spec motors. It delivers the same powerful output as the VFS-FR2.
