Tonight I finally got around to cutting down the left motor mount (at least, I think it's the left one) for droid #2. There is such a tight fit in the battery boxes that there isn't any room for excess baggage.
The motor mount hangs down about 1/4" beyond the bottom of the motor. In this picture, everything is rotated 90 degrees, so the overhang is on the right.
I marked the area to trim.
Well, at least it's not steel.
Now the motor mount doesn't hang below the motor.
That was so much fun, I'm going to save the cutting of the right motor mount for another day. Possibly tomorrow.
