Baby Biwinger
If this photo of the Baby Biwinger and some of the modern micro R/C equipment (above left) does not get your “little grey cells” working, nothing will. The Cox Tee Dee .010 from the model along with a genuine K&B .020 Infant (above right) that was used for gathering information on the type. It is interesting to note that the mounting plate on the K&B can be rotated to just about any position for easy mounting. The K&B .020 Infant along with a genuine
red and gold Cox Tee Dee .010 in jewel case (below left). It is ironic that Lud Kading and John Brodbeck had originally intended for the Infant to have a .010 displacement, but the prototype was deemed not up to snuff for the commercial market and so the larger .020 size was chosen. Two classic .020s side by side (below right). An interesting contrast spanned by only about 10 years of development.
Not a leprechaun’s “crock of gold” (at left) but potentially just as valuable. Look at all those .020s in that pickle jar—not parts, but complete working functional engines like the example in the foreground. There may not have been as many K&B .020s in one place since they left the factory in the early 1950s. This treasure trove of K&B .020s belongs to a prodigious collector in Wichita named Bill Schmidt. If you choose to only build a glow powered F/F here is the model with three potential candidate engines (above). From left to right, the original stock engine, a K&B .020 Infant, a suitable, more powerful and more plentiful Cox Pee Wee .020, and finally the equally powerful, lighter but less plentiful Cox Tee Dee .010.
