OTOH, if the carpet monster eats a body screw, that sends me to Alan at scale racing.com ti order a replacement which may or may not show up in time for the race, while i have virtually identical screws, save the drive style in my kit.
AS far as the unfair advantage goes. A spec race really ought to have spec controllers if it is to have any meaning. Perhaps spec races should specify the use of the club controllers to level the playing field.
