New ailerons and CG

[Battfly]

Added ailerons to a 60" e-glider. With the added wing, what happens to the CG? If I added ailerons equal to 10% of the wing, do I move the CG back 10%?
Thanks.

Are these new ailerons added to the rear of the wing, extending the chord?
For all intents for this, determine the current c.g. in percent of chord, and place the new one at the same percentage of the longer chord wing.

Thanks Sparky, that's what I guessed. Yes, the ailerons extend the wing and maintain the original wing contour, almost full length.
