HobbyStar 3660 4-pole brushless motor provides increased torque when compared to a standard 3650 while still providing top-end power. Versatile waterproof design allows you to drive in extreme conditions and motor leads come with pre-installed 4.0mm gold-plated bullet plugs for easy, no-soldering connection.



  • 4-pole motor with 12-slot high-torque design

  • High-RPM ABEC5 oversized bearings
  • Precision balanced rotor for smooth operation and maximum RPM
  • Super-thin (0.2mm) stator laminations

Which is better for general bmx track bashing, 3660 or 550 3800kv? Want to run 3s in 4wd short course buggies. Very dusty track.
The 3660 in 3800kv would be a good choice if using running 3s power.
