On the first picture you can see that I began to build the wheel well with 1/8'' balsa. In the second picture, I added a 1/8'' part of plywood to the top surface of the platform. It doesn't really mather how much weight I add around the nose wheel area since the black weight you see in the second picture is actualy meant to be on that platform for balance. If it become too nose heavy, all I will have to do is remove a chunk of that weight or change it for a lighter one. Since weight is not really a problem, I will add as much reinforcement that I feel is required to the front part of the airplane.
