Hello People,

I am a new member of the forum. I have been reading the forum for a couple months and I have finally deciced to join and start contributing.

I am designing a large RC airplane from scratch and I have been able to identify most of the parameters I need to start construction. These include sizing, configuration, stability, structural design and other things. However, I would like to know if there is a way to calculate how much the Cl on the wing changes when the control surfaces are deflected.

Any ideas would help. Thank you.
