Agreed, and if you have a terribly mismatched set of brakes, like I have, then you can use two Xicoy controllers and mix them on separate channels to get straight braking. Oddly enough the two Xicoy’s are less money than most single brake controllers!

or you can use the Assan AG63 brake gyro which automatically adjusts the brake voltage on each brake to keep the plane straight.
Much cheaper and more effective.
