hi Oli rc7 well to tell you yes it does effect the car in mid air especially outdoors in windy conditions it can alter the landing of the vehicle , it effects how it will land nose up , down , landing side ways due to a cross wind , drifting l or r , some people alter the wing as putting holes in the back part wing for the air to pass through it , to help make it a little more aerodynamically stable, also too large a wing can slow the vehicle down , on the ground and in the air , on the ground you might gain some better traction because of the down force of the wing , but you
will lose speed and direction when landing too ok mugey
