  • Product Description

    This is an update to our popular FTC legal* motor.  For better compatibility with the new REV Expansion hub upgrades were made to the encoder and power electronics for the 2017/2018 season, including gearbox and an encoder mounted to the back side of the motor. 5mm hex output shaft makes it easy to connect gears, sprockets, wheels, etc. Encoder cable included with motor. Motor specifications are similar in size and power to other FTC motors with a more convenient output shaft.

    1. V2. Seems to be a great motor, they just came in. Some small changes to be aware of here.

      1. The motor shaft is well over the specified 25mm length. It is about 19mm" longer than the previous generation. Maybe just the motors we got, but the length is a welcome addition in most circumstances.
      2. There seems to be a newer bolt pattern, we could normally get all 6 screws into the standard motor mount, but this time we were only able to use 4, not a big deal.
      3. The gearboxes seem significantly quieter than the previous generation. Haven't opened it up to see if its different.
      4. Love the plugs on the back rather than just a hunk of cable sticking out of our previous motors. Makes it easier to swap out and you don't have excessive cable lengths and unneeded connection points.
