We left the CG at the fatory recomended limits. The airplane was flight tested at both limits to a stall onset and performed satisfactorily. It only performed poorly when driven deeper into the stall/spin entry with the cg approaching the middle of the envelope. This test (deep stall) wasn't attempted with the CG in the rear half of the CG limits for obvious reasons.
