My cg is at 6-1/8" and I wouldn't want to fly it any more NOSE heavy. The plane is quite stable and a joy to fly at this CG setting. It does couple a little during hovering but the tradeoff is better flight characteristics during all other maneuvers. It doesn't drop the tail during landing at this setting. No weight was needed to achieve this CG with a Saito 91. The prop is a 14x6 and I am pleased with its performance.
