Nope you will be able to tell the difference in snaps, spins, and also in
slow rolls or point rolls, and obviously in the upper ¼ loop-corners at the
end of uplines.

	The question I am asking is. If I sneak in and strap on 1lb. to the
wing tube on your airplane right on the CG and you did not know. Would you
be able to fly and say someone put more weight on my airplane. I bet you
would say I think my engine is not running as well as normal.
