This one is simple, start the game build some speed then pick a side and climb it the roll down at the middle go flat. And power up other side turn and ball again roll down and in the middle flat again climb up the other side and hit any rock at angles you up while turning back to where you started.
Once flying up wait till you slow tap
twice and gain more height then pull both triggers till you see the dust and then head back to where you started. Job done.
