Installation notes

  • One 6250 package includes the 3350KV brushless motor and three-channel ECM. A compatible original TQ transmitter can be bound to the new ECM for steering and throttle.
  • Use the included motor plate/hardware and reuse the specified ECM and transmission screws. Keep servo wires clear of rotating parts.
  • Use a 2S LiPo supply and retain the specified wiring arrangement. This system is not a 3S conversion.
  • Choose Sport, Trail or Crawl mode for the intended braking and reverse behavior. Additional remotely operated functions need suitable radio controls.
