    Default Wing Spar Question

    I have just started building my EX2. When I was laying out the wing spars and looking them over I noticed that the area around the inboard topside hole on all of the wing spars is roughed on both sides of the wing spar. I was wondering if this is normal and if it is normal what is the purpose of this roughened area?
