Build my first kit - a SE, however when I slide the wings on to the wing tube, one side, the left wing, will not fit flush against the fuselage. It touches at the front, but then has about a 1/8 inch gap all the way to the trailing edge . Will this have any effect in it's flying characteristics?

I'm anxious to get it in the air and don't really want to go through major modifications, unless absolutely necessary. Any reply is appreciated. Thanks.
