Details

The HobbyStar 550 4-pole brushless, sensorless motor is based on the same design as our powerhouse 540 sensorless motor, but features a longer 550 sized can for extra torque. The perfect motor when a high-torque, high-performance powerplant is required such as 4x4 short-course trucks.  A beautifully machined T6 billet-aluminum housing contains a 4-pole, 12-slot high-torque rotor spinning on High-RPM ABEC5 oversized bearings for a powerful, reliable motor choice for your 1/10 scale vehicle.  Comes with motor leads with 4.0mm bullet connectors already installed. Available in a wide variety of KV ratings.

  • 4-pole 12-slot high-torque design
  • CNC machined 6061 T6 billet aluminum can

  • High-RPM ABEC5 oversized bearings
  • Precision balanced rotor for smooth operation and maximum RPM

Running the 3800kv on 3S (not recommended)
On both a SC and MT and it's stupid fast
Motor doesn't overheat as long as you don't run steady at high speed

I put this 3500kv in my Terremoto 10 to replace the stock 3000kv 2 pole motor and what a difference. The truck on 3S is insane, so fast and plenty of power. I managed to rip the tire off the wheel from speed. (Posted on 1/15/2016)
