IIRC, that is a straight chord wing. If so measure the chord, including ailerons, and go back 25 -- 30% and your machine will fly. Example the chord is 12 inches. A CG within 3 - 3.6 inches will fly well. If you wish to go outside the box, then do so in short increments, especially if aft.

If the wing is a straight line taper then measure the average chord and use the above procedure. MIND YOU that this is NOT the actual AERODYNAMIC chord but it will be darn well close enough for a standard model airplane.

Example: Tip chord is 8". Center chord is 14". Find the 11" spot and measure back 2.75" to 3.3". Machine will fly.

Balance it just behind the main spar (1/4") and it will fly like a dream. Mine does...
