    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.
