You can go for 24"x5" wing. Check my AUW 400 gm plane that completed in 220gm.
9 gm servos with wire and horn weights appx 11gm. Prop 2gm, Pushrod 3gm, + Airframe weight.
So, make it like slow stick with 4x7" = 28" like \ _ _ / with Al. bend wire (Dihedral wing).
Insted of stick, make coro fuselage just sufficient to fit all electronics to make it thin and less weight. Adjust CG first by adjusting wing position with rubber band and then make fixing dowel position.

Just have a try. And believe me, go to a large maidan to test the flight. You will be amaized the flying comparing your local ground. Search for a nearest empty field preferably after cutting corn just ensure 500mts open at least.

Slow Flyers require very light wing loading, like a glider, something like
 11g/dmē  (3.6 oz/sq.ft).
A 24" wingspan with your stated AUW wouold mean you have to fly it like a warbird to keep enough lift. Either use lighter motor, ESC, lipo, or increase youe wingspan to 30" or more. 

you can copy these specs of a GWS Slow Flyer:
