Why would Brodak kit such wretched models when the Midwest ones are (still pretty wretched) so much better? What a waste of time and balsa! Who is advising this guy? These designs are not only incredibly obscure, even Sterling bailed out of them ASAP! Rare is one thing, junk is another.
The only possible salvation is if they re-structured the models to weigh 7 ounces and take an .061. THEN they would have something. As long as the 3-view and airfoil are accurate, it qualifies for Classic or Old Time as needed. Internal structure is not required to be the same. And it turns out that their Baby Clown is not terribly close to the dimensions of the original design. The guy responsible for the Brodak kit challenged me on this, saying he had a copy of the original kit in his car. He did, we compared them, they were WAY off! However, since I had been allowing them to qualify for the Leprechaun "Pot 'o Gold" trophy, I have not only allowed it but have of of my own (.035 Diesel power about to be upgraded to .061 diesel).
I am all for reviving old designs, but there are so many with more merit that would be desirable. The Wee Duper Zilch would fly loops around those Sterling models. Kitted? NO! Standard Clown, modified to use a .10 or .06, NO. How about the Shark .15? That flew very, very well.
Jr. Nobler? Yes as originally kitted it was a slug, but there is little wrong with the basic design. In fact, a lightened (but accurate by the above standards) versions is in my building que. I have a mold for the canopy, scanned and physically copied plans, scans of the die-crunched wood. When I get through, it will be (accurate and legal) light and compettive. I will put on a Medallion or Tee Dee .15 engine. Actually, the size is just fine for an OS 10 fp, but that isn't a Classic engine, though it would be a better choice for regular competition. (You could always g0 electric and get lynched!)
If I were designing a .15 model today (I plan to next week

) it would be about 325 sq.in., have working flaps and have the "numbers" of whatever Dave Fitzgerald is flying. Stability scales very accurately, although wing loading doesn't. And I know how to scale wing loading.
