No, you weren't. that's 15-21 fps.

With a single speed gearbox, having 15fps would make your robot nearly impossible to drive and turn.

Most teams with shifters have a high speed of 12-16 fps and use their lower speed for more maneuvering.

With no chain reduction, the kit gearbox will get about 10.5 fps on 6" wheels. That's probably geared too high to be useful, it is also most likely not traction limited.

I would recommend the KOP gearbox with an additional 3:4 reduction in sprockets. That will put you at 8 fps, which is pretty good for a single speed robot.
