Course Unlocks
Complete the following races by getting a Bronze Cup or better (i.e. 3rd Place or better) in the Championship mode of the game to unlock the following courses (there are 12 in all with each course being flown forwards and in reverse): Note: Reverse in this case means that you literally fly the same course, but in the opposite direction as opposed to a "mirrored" race course where a left turn is turned into a right turn. Normal courses are denoted by a green symbol with two circular arrows, and Reverse courses are denoted by a red symbol with the circular arrows facing the opposite direction.
