Hello Pattern guys

I just maidened my new Arrow, wearing a Picco 80 RE.

I suppose I have the CG wrong but please let me know if I am missing something. The plane flies "unstable" in the roll axis. It tends to increase roll to whatever side it starts banking. It is also extremely responsive to aileron input. I set up low rates at 65% w/ -50% exponential, and it is STILL too responsive.

I have checked everything and the plane (bought used) is perfectly straight and very light.

Supposing it was tail heavy, I added 3 oz of lead to the nose. It improved some, but seems to require more!!!

Totally puzzled. I supposed such a nice build should not require nose weight if using the Picco 80.

Help!!!
