I built a Kadet Senior once, but that was over 10yrs ago. I didn't think it was that wide.
How about the Hobbico trainer planes, 40-60 size?? one of those may work. I know the trainer 60 is a large plane.
It wouldn't be that hard to make a wing. Just find the airfoil shape that you want and adjust the size to 10 inches on a copy machine. You can cut out the ribs from that pattern...very easy to make. I have enlarged the wing of the Littlest Stick before.The plans can be downloaded and printed out on a printer. Then enlarge the airfoil on a copy machine. I would add two more ribs to each wing. Kinkos can enlarge the whole wing plan for you. Just an idea.
