Zach,
I converted a 4* 120 to a sorta scale Thrush S2R in 1996 to use as a practice plane for Top Gun. I wanted an airplane about the right size and profile although the cross section and power-to-weight were way out of scale with a Saito 1.50. The way I accomplished a reasonable chord to span ratio was to leave off the strip ailerons and build "scale" barn door ailerons and flaps into the rear of the wing. This was a fairly simple mod by just trimming off the ribs and capping them with subspars to hinge to. I doubt you will be able to make a very accurate scale plane out of the rest of the kit either considering the width and cross section of the fuselage. You may want to check the cropduster r/c link-
