I believe our team is using the
F310 model
Two years ago we tried using the wired 360 controllers and didn't like them due to there being a large deadband about the analog sticks center.
Our drive team has been practicing with the F310s this year, they've been approachable for the students and seem to be well received. They certainly seem to have an easier time controlling tank drive on this type controller as opposed to two joysticks.
