Yes Luke, we should give this a try for our FTC cars at least since drivers do not switch cars and are stuck with what they get for the event. With our other "IROC" classes everyone drives each car.
FRC's PC, LS & FTC classes have 18 x 2mm bar magnets altogether - how about we do some of this magnet "old school" testing with their strengths and sort them out with this method for (3 x 6) light, medium & strong and change the 1 or 2 that may need to be changed...
We can workout which one of the 3 magnet strengths goes in which of the 3 six car classes.
