This is what 'Wing" looks like on the back of mine. In this picture I had set the angle of the wing topside to be neutral,but due to the underside of the wing it caused it to lift the rear of the dragster. You would think on a 1/8 mile track it would make no difference but I knew something was wrong by the 330'mark and by the 1/8 mile it was on the raged edge. Don't be fooled by thinking a wing or rear spoiler makes no difference like some people think to you get up to 140-150 mph.
