I just purchased a Top Flight AT-6 and need check the CG. Can someone tell me where the CG points are on this plane?

I don't know whether you have the ARF or a kit-built model but it makes no difference. The CG is 4 1/4" back from the wing leading edge at the point where the wing fairing is. That is also the point where the wing transitions to a slight taper at the front. I've used this CG and it works fine.

Good luck......and you'll enjoy her.
