I dont really know why this is making BBQ out of my PC because I had more complex things running smooth on it but:

I present to you the Butterfly!

Instructions

• start it on the water
• press AG4
• throttle up
• yaw to steer
  (drives like a normal ship eh?)

If you had enough of this dumb surface do this:

• keep driving
• press AG7
• trim all the way up
• pitch up
  (The ship now should move up into the air)
• if you're out of the water you can release pitch (It should be fine)
• move up to the altitude you want
• Trim slightly down untill you see the ship moving verticaly in flyby

(now you can steer again with yaw. you can also roll a bit for the effect.
while in the air, the ship can keep turning - just steer against it untill you see the smoke is lined up)

The other stuff:

AG 1: Activates top gun turrets
AG 2: Activates bottom gun turrets (Gear for the Gunners Cockpits)
AG 3: Activates top AA turrets
AG 5: Activates side AA turrets

PS: I don't really know why I put the Ship engines for the propellars in a spot where ypu cant really see them...
