So today I was flying one of the planes I designed, and the wing snapped and it crashed. I ended up cutting the front of the plane, and I was wondering if I should rebuild the front of the plane, or just keep it as it is and put the wings on.
You want the plane to balance, that is the CG, at 25% of the wing cord. It's hard to tell form the picture, I'm guessing your plane has a 6 inch cord. If so your CG should be about 1.5 inches from the leading edge of the wing.
