Gurney flap only applies to Wings ok ,what is the proper technical term to describe a gurney flap shaped protrusion on a Leading Edge attached wing AKA spoiler?
Why does the rule book for Bonneville ,El Mirage, ect LSR say that Granny flaps are allowed on a Bonneville spoiler, the same rule specifies that the Leading Edge of the wing be attached therefore it is a spoiler with an allowed Gurny Flap? I don't know of a more technical writing than a rulebook for racing.
Southern California timing Association 2019 rules and Records , Rule # 4.CC.8 pg60 , 1 , "Gurney flaps are allowed but cannot extend above or behind the spill plates" (2"aft or 8"above)
