The picture I show is on all the boxes that were made by Scientific. My model looked just like the picture but the wing was only 1/8" thick. It was bought in the mid 1970s about '74-'75.
The rudder ( as shown in the ad) extended down the back of the fuselage and of course had to have a cut out for the elevator.

The one used by Black Hawk models is simply a fin on top of the fuse with no actual rudder behind it. I am sure it serves its function well and it looks good too. However, the Black Hawk model version just does not appeal to me at all. To me it isin't really the same plane somehow. Forgive me for being picky but it must have been the shape of the fin/rudder that drew me to this model in the first place. As simple as the model is this is the only thing that gives it any style aside from the open cockpit. Well, The decals do as well and the sharp contrast of the banding on the wings but that is just paint.

The rudder/fin change is a styling difference which my personal taste does not approve. Like if you were to take a '57 Bel Air and put '59 ford fins in place of the original. All else being the same, it just wouldn't be the same.

I know that I am able to order the plan directly from Mr. Musciano but I don't want to bother this good man over something so trivial (except to me).

My search goes on...
