Hi Oberst, man you are going at this project full blast! Can't wait to see your Z scaled out. Thanks for the pics, I can see there are lots more scale details that I can attempt. I have used the CG as shown on the plans. When balanced my nose is slightly down. This model flys great, and landings are good. It does like to dance around a bit on the roll out, but is controlable. Spacing the landing gear wider apart as per the full size, will help here i think? Duane
