Short and sweet question,
Top flite models at one time manufactured a delta wing called the "Holy Smoke"
I am interested in buying a used one from a member here at RCU but he doesn't
remember where the center of gravity should be located. I can experiment with the
elevator and aileron throws.
How do I determine the correct CG on a delta wing aircraft?

Or am I really trying to determine the MAC so I can then Find the correct CG
