As you can see from the way the wing is constructed that there are only two vertical reinforcement bars and no horizonal reinforcement bars other than the outer skin top and bottom. This plane is old so I think I'm going to try to reinforce the wings. I have several ideas for vertical and horizontal reinforcements but I don't want to add too much weight and alter the center of gravity of the airplane. Look at the illustration below and you'll see how the wing is made and then a couple ideas of how I can add reinforcement to it. Any horizonal or flat reinforcement will give the wing strength from front to rear and help when the wing contacts something it won't tear from front to back. Any vertical reinforcement added to the wings will help with the loading of the wings or in other words the load that the wing will support. Whenever you pull up on the elevator and an airplane is in a high speed movement as the nose of the airplane pulls up then the wings are forced upward because the body of the airplane is still trying to move forward trying to both push the wing down in the center as the air pushes up on the two ends. I am going to try to add some vertical and some horizonal reinforcement to the wings without adding too much weight I think later I will try to rebuild this airplane from scratch out of foam and change just a few things but maybe try to redesign the wing to be much stronger then maybe do a crash test to see how the result held up.
