Ko Propo 30224 BSx5A-one10 Grasper3

Carve corners with newfound composure using the Ko Propo 30224 BSx5A-one10 Grasper3. Building on the celebrated Grasper's road-holding reputation, this low-profile brushless servo introduces KO's exclusive AGR function, reading your machine's behavior in real time and quelling understeer. Front tires surrender their grip more willingly, letting you carve stable, self-assured lines lap after lap.

Key Features

  • AGR (Active Grip Response) suppresses understeer in real time

  • Servo detects cornering behavior and extracts front tire grip

  • Newly designed aluminum top case built for Grasper3

  • Torque increased by 20 percent compared to previous models

  • Serial compatible for ultra-high-speed communication and dramatically improved response

  • Servo parameters adjustable directly from the transmitter

  • Brushless motor with hard anodized aluminum gears

  • Dual ball bearings and hard servo gear shaft

  • Aluminum heatsink middle case and black servo leads

  • Gold-plated connectors

Why Choose This
Drivers battling insufficient grip will appreciate how AGR steadies the chassis mid-corner while drawing more from the front tires. Smooth, composed turning replaces nervous corrections, handing you finer command of the machine. Torque gains and serial communication sharpen every input, making this servo a formidable ally for touring cars and buggies alike.
