Grid Leaks
Ever notice how Grid Leaks (Ace R/C newsletter by Paul Runge) basically did not give hardly any coverage on the first generation proportional equipment and continued to feature mostly single channel gear, including tube type stuff, all the way into the mid-1960s? One could assume that Runge was heavily invested with Kraft, Ecktronics, Inkman, Baisden, Phelps, and marketing their offerings through Ace R/C , long after they were essentially obsolete. It seem odd to me that so much effort was put into these DIY projects when you could buy much better equipment for a just a tiny bit more money.
