Bowhunter,
The closest match that I've been able to find so far is a model sold by General Hobby. They offer, or did offer, numerous cub models. Two of these bear some resemblance to your model to me. The first is out-of-stock model with a 71.5" wingspan clad in the conventional yellow cub color-scheme. It only has one working picture of the 71.5" model and it is not very revealing. It does show a little of the wire main landing gear. It also appears that they covered the forward-most side window in monokote for some reason. And, of course, they don't offer an online manual to compare model similarities and differences. The graphic scheme doesn't match at all but, like I mentioned earlier, they could have offered a alternate scheme at one time.
The other model is a Cub with a 80" wingspan does have photos which reveal a little more of the model's construction. This one is also out-of-stock. I know it's not the same size but it does appear to share some of the same construction features as your model. The formed wire main landing gear construction and mounting method appear similar to your model. Also, the method of wing attachment is the same. I am assuming, of course, the 80" model and the 71.5" model share the same construction. In fact, there's no way to be sure without other photos or studying the instruction manual.
Anyway, it is by no means, a positive I.D but merely the model that I've found that shares the most in common with the photos of your model. I'll include the links to the product pages on the General Hobby website. Take a look and let me know what you think...
