New Focus Question

[Ernest Schmidt]

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.
