  • HobbyStar boat motors are engineered to provide maximum power and cooling for your RC watercraft.
  • Open endbells radiate heat away from the motor, and cooling jackets are available separately for all motors. Motor leads come with pre-installed 4.0mm gold-plated bullet plugs for easy, no-soldering connection and a wide variety of KV's ensure a dialed setup for your application.
  • 4-pole motor with 12-slot high-torque design CNC Machined 6061 T6 Billet Aluminum Can High-purity copper windings maximize efficiency High-RPM ABEC5 oversized bearings Precision balanced rotor for smooth operation and maximum RPM Super-thin (0.2mm) stator laminations
  • Maximum voltage listed is an approximate limit that can be applied to motor when set-up properly. Any motor can overheat to the point of destruction if overloaded (too much prop, too heavy of a boat etc.) even when running well under the maximum rated voltage.; It is critical to monitor motor temps and any new setup and adjust accordingly to keep temperatures in check (under 170F is recommended).
