I have my Focus Sport all done except the pull-pull cables and the graphics from Bad Brad. I checked the CG today and this plane is really tail heavy. I would say it's from the Saito 125 being lighter than the YS 110, and the 1/8" wood shims I had to use for the elevator servos. Not much room to add any weight up front and by my bathroom scales I'm alread around 8 1/2 to 9 lbs.
