I am thinking about doing some simple mods to a Balsa USA Enforcer. I want to add some small canards and LEX to the plane. The three pictures show roughly what I would like to do. Total lifting area added in front of the CG is 25 square inches. I am curious how much this will affect the CG considering how much wing (1000 square inches) is behind this small mod. Any suggestions out there? Does anybody think that the CG would be greatly affected (no more than 1/4 inch movement at most)? I would like some opinions or suggestions to do it or not to do it and what you think the effects to the CG might be. The last picture is not exactly to scale with the overhead one as far as in exact placement. If anybody needs any information to make an educated or informed guess, let me know.

Thanks in advance!
