You could build a simplified wing for your first model - minimize the bells and whistles on the first wing - to help with your build schedule, keep it lighter, etc. Then prove out the rest of the airframe, Cg, etc.
Then later, build a second wing with one or more additional functions (slats, or wingtip speedbrakes (decelerons), etc ). Since there's no landing gear details that interact with the wing... Then, if you run into unexpected slat difficulties (for example), it doesn't kill the remainder of the project. Just a suggestion.
