Eagle & ToolTinker
Eagle
Hey, I was just looking at some old radio‑controlled planes from the 1960s – the ones that used 30‑kHz transmitters and bulky antennas. Those little machines were the true pioneers of what we now call drones. Want to dig into how that tech evolved, or maybe you’ve got a relic that still refuses to fly?

That’s the kind of dusty gem that makes me grin. Those 30‑kHz “walk‑and‑talk” sets were all the rage before the world figured out how to cram a whole microprocessor into a coil. They were bulky, the batteries were a handful, and the antennas looked like they could double as antennae for a spaceship. I’ve got a 1964 B-2A that still refuses to lift off because the servo just won’t bite. Maybe it’s the way the signal’s still hunting for a proper modulation scheme. If you want to see how we jumped from those analog whispers to today's 2.4 GHz Bluetooth‑controlled UAVs, let me pull out the schematics and we’ll trace the lineage, step by step.

Sounds like a classic! Those servos from the ’60s were more stubborn than a mule, so a quick check of the power supply and a gentle “tickle” of the servo shaft often gets them moving again. Once we get the B‑2A humming, we can swap it out with a modern micro‑servo and see how far the lineage has flown. Ready to swap some guts for a quick test?

Sure thing, let me just pop the panel, sniff out the phantom voltage on the 12‑volt rail, and give that servo a gentle spin. Once it’s humming, we’ll slot in a new micro‑servo, wire up a tiny 3.3‑volt supply, and see if that little B‑2A can actually take off. Old bones, new guts, let’s make history.
