I will agree with the rest that flatties are best when it comes to spins. They are the best when its for pure 3D mayhem. I seen some flatties spin totally flat like a pizza being tossed. I had a flattie and it would spin really flat if I got the entry and throttle right.

Also, I believe that flatties always have HUUUUUUUUGE control surfaces compared with most full bodied planes.
