    An Excellent Motor

    This motor is a very good choice for any team and any skill level. The motor is powerful enough that two of them can move the entire robot quite quickly. As stated in the title, this is an excellent motor.

    4 of these beasts is more than enough power (geared down through a toughbox with a 12.75:1 ratio) to move a chassis built to FRC dimensions, and me on top of it, while pulling another person

    Review.

    If it's a 2 star or below maybe you could pop up a little check what applies section so you can collect data. I hate having to write. Collecting data on your good sales is nice, but annoys customers like me. I use you almost exclusively because I know you know what I need.
