An airplane that I made out of my floating machine engine and a simple stabilizer. It only uses air friction to fly, instead of using the stupid geometry controller.

Hold the right arrow key to fly, and use the up and down arrow keys to move up and down.
You'll probably have to hold down to fly straight for a bit, and then just balance it out with your keys.

If you want to make it faster and stronger, there's a bar at the front of the flight engine that has a script on it. It'll be e.other.airfrictionmult := 500, or some number close to 500.
Make the number higher to make the plane faster and stronger, or lower it to make the plane slower and weaker.
