I notice they dont tell you if you should use the fron part of the coroplastic hatch to protect the battery on ladings, some are covered and some not , which is proper , i thought of the cooling also
The instructions call out a demension of 8.5/8 in front of the nose . in other peoples photos , I see that thaey use the hatch as a CG point , which is 8 . inches from the nose , does anyone know from exsperience which is the proper CG gor the wild wing?

You are not going to get a useful answer unless you state what exact airplane you are talking about or at least a link or photo.

A search here at RCU on Wild Wing pulled up nothing useful to identify the airplane.
