Best Strategy: Keeping low and getting boost from paper windmills. You will need the Hurricane, Rudder control, and Lightweight upgrades to do this properly. Improved model is also good, but you won't be using the engines because you'll be relying on the boost from windmills. Thumbs up so people can see!
So far, I have finished 10 levels without any strategy whatsoever. Hooray for jumping in all directions and winning without knowing what you have done.
