With a waterproof design featuring recessed cooling fins for added clearance, the HobbyStar 4068 4-pole motor is a potent powerhouse for 1/8 buggies.   Features the same 4-pole design and a 12-slot stator from the standard 4068 motor in a lighter-weight can.  Pre-soldered 4.0mm bullet terminals to make installation a snap.



  • Brushless, sensorless 4-pole motor
  • Waterproof design
  • 12-slot high-torque stator
  • CNC machined 6061 T6 billet aluminum heatsink can
  • High-purity copper windings maximize efficiency
  • High-RPM ABEC5 oversized bearings
  • Multiple mounting holes with M3 and M4 threads
  • Precision balanced rotor for smooth operation, reliability and maximum RPM
  • Stator-Super Thin (0.2mm) laminations
  • Precision engineered for maximum energy conversion

 Voltage recommendations in chart are guidelines for the voltage you can safely run.  It is still critical that the user monitor motor temps and adjust gearing if necessary, any motor can overheat to the point of destruction if over-geared even when running at or below the rated voltage.

Amazing power!Review by Freedom
Bought this a year ago an it took my slash 4x4 to a whole new level. Have it running on mamba x. Great motor stays cool. Lots of power. Can't beat the power or the price. A year later still going strong!
I will buy again. (Posted on 5/25/2021)

Could I run the 2650kv version of this on a HW max10sct 120A esc? Looking for something that has a bit more trq than the HS 3665 3100k
Yes you can, it's important to always monitor motor temps to dial in gearing (should never exceed 170F) but yes that ESC will work with this motor.
