While the wings look "over-spanned" for scale appearance, this need not be the case, as the three "keroperox" (JP-4/hydrogen peroxide) AR2-3 rocket engine (and RCS thrusters)-equipped NF-104A aircraft (see: https://www.google.com/search?sxsrf...i10.zJKT9DrqVXI [NF-104A plastic model conversion kits are also shown here]) had extended-span wings. (An NF-104A model rocket--or PMC--would make an interesting clustered-motor model [with two--likely different-sized--motors mounted in the GE J79 *and* the Rocketdyne AR2-3 exhausts]. As long as the model's CG point and the AR2-3's thrust line were properly lined up, so that the thrust line passed through--or very nearly so--the CG, it should fly straight, although the motor in the angled AR2-3 section might make it "walk" sideways ["downward," with respect to its wings] through the air.)
