The manual says 7 7/16" from leading edge but I've heard somewhere that this incorrect. What is the correct CG? Mine came out severly tail heavy. It's gonna take around 4-5oz to balance the damn thing at 7 7/16". I'm using the saito 100 and I guess I should not of put the rudder servo in the tail. Looks like it would of came out just about perfect with the YS110 since it weighs about 6oz heavier than the Saito 100.
