that's a great maiden report. Iknew you were gonna love that plane.
When you get the CG moved you'll like it even more.
If it drops the nose in flat rudder only turns (no aileron input) then I might suggest is some elevator to rudder mix. About 4 or 5 % up elevator on each side of rudder. It'll help your stall turns and your rolls.
Have fun
