Chad, I don't know why you are in such a hurry. This is a plane you should NOT plan on flying until near the end of the summer. You still need time on your trainer. As much as you don't want to hear it, it IS the truth. You are on a fast track to destroying the 4* on it's first flight. You are rushing the build and not understanding the various steps prior to doing them. You are also using Home Depot materials. There is a reason why LHS materials cost more, it is better(in most cases). If you have to wait another week to afford PROPER plywood, so be it. That's what I do. We all have to budget our building expenses and sometimes things have to wait until the money is there or go into debt. I don't recommend debt, it adds up in a hurry and is an evil thing. Ask your dad about the evils of debt if you don't already know.

The plane. The piece everyone is calling a "stringer" is, I believe, actually an aft spar. Your plans will actually name it. If it is a spar, it is even more structural. Either way it MUST be repaired. If it had happened near ti tip I would not have as concerned but much of the stress will be near the wing root during maneuvers. I had you place the servo in an inner bay to keep the rotational mass down. During a fast roll, there would be less energy directed on it, it could have been further out but didn't need to be. You have cut notches in the edges in of several ribs, this causes stress points in them also. Proper procedure would have been to drilled @ 1/2 holes in the center of the rib just behind the main spar in each rib. Then run a wire guide tube to the root to protect the wiring from chafing on the wood. You should have made cardboard or balsa templates of the servo trays in the wings and gotten everything fitted. Used the templates to cut mounts from 1/8 aircraft plywood from the LHS and test fitted it for final fit BEFORE and glue came near the plane. And when the glue came near the servos should have been in a box somewhere safe.
You now have a servo tray, at least 2 ribs, center sheeting, stringer/spar that need repair. All this on a NEW plane. [:@]
When I'm doing a build, there are days when I may put on just 1 or 2 pieces and spend an hour or 2 planning the next step, gathering materials/supplies for the next day.
I'm not trying to be down on you. I do want you to slow down and think things through better and do less damage in the name of progress.
