RE: Nitro planes Ultimate 40 CG
Hi
I just finished my Nitro 40 biplane today. I been emailing with opjose today and he told me the CG should be around 100mm from the leading edge. He sure has been a lot of help to me.
I balanced it on the top wing and lucked out with the CG being right on. Tomorrow I maiden it.(Weather permitting) here in Wisconsin
Good luck with yours
