Dene: Hello
I think you will find that the CG remains very close to where it was originally. What will move back is your center of lift. The CG may still be within limits but you would need to check. Moving the Center of lift rearward would increase the work load of your horizontal stabilizer as it will need to provide more down pressure to balance your load /lift. I'm not saying it couldn't or shouldn't be done just realize what he results will be and adjust accordingly. Russ Breckenridge, MN asir...@702com.net
