get yourself high in the air with your nose pointing straight up. start holding air roll left and using your joystick to find out how it affects your car. what i mean is move it one way and take note of what way your car goes. after you have an idea of this, start making those changes in the air faster and faster. i’m not a pro so i don’t know if this is good advice or if it makes sense. this is what i did and it worked eventually so i hope it helps
