Product details
Description
Engineered to dominate the track, the HobbyStar 540 Pro V3 Competition Brushless Sensored Motor in a 4.5T Modified ET configuration delivers championship-winning power and elite efficiency for 1/10 scale RC racing and high-speed drag applications. Featuring a re-engineered open-window vented aluminum can, this powerplant maximizes cooling airflow to keep operating temperatures minimal during intense runs.
Underneath the sleek black and gold exterior lies an advanced internal sensor board, high-strength neodymium rotor magnets, and a drag-race optimized high-torque rotor and stator setup that provides explosive bottom-end punch and linear throttle response. Built with lightweight stators, gold-plated solder tabs for ultra-low resistance, and titanium-nitride coated aluminum fasteners, it combines extreme performance with competition-grade durability.
Operating at 7,260 KV on 1 to 2S LiPo power with a maximum current draw of 110 Amps and 480 Watts of peak output, this motor gives hobbyists and serious racers the precise control and blistering speeds needed to leave the competition behind.
How to use
- Install the motor into a compatible 1/10 scale RC vehicle chassis using appropriate mounting screws.
- Connect the three motor wires to a matching sensored electronic speed control, attach the sensor harness cable securely, and gear the vehicle properly according to track conditions before running on a 1 to 2S LiPo battery setup.
