--- General stuff--- Keep the average speed as high as possible, optimizing between boost that you get from lines, cubes and circles ("Boosts", "Black boosts" or "BB") and a shorter path * overall *
The engine limits your maximum ground speed Open wings limit your maximum speed in the air So the maximum speed is reached by getting a cube / passing in a circle with the wings retracted
The lines do not appear active if the wings are not closed
--- Movements on the ground --- The wings slow down and change the center of gravity of the car, widening the curves a little It is better to take off while boosted in order to mitigate the slowdown caused by a take off
--- Movements in air --- Each flap in the air costs about .05 secs a "flap" in general will slow you down a bit, gliding is slower than driving if you retract your wings before starting to glide -> "half flap" the wings slows you down progressively since they start to open And being the only way to move in the air after taking off, buffering one direction and an half flap seems like the best way to adjust a trajectory.
--- Routes --- Since the finish line can be crossed by both sides, it is often more convenient to take a longer path to bring back one cube, which however positions you better for the next.
