The question is, what is that little bulb in the middle?
Its for the morse code telemetry system. That was the upgrade the first one was a little man with flags.
no it's a Tube! way better sound quality than transistors! and it was pulsing too... I guess it's the first iteration of the led Show code.
It is a mercury switch for orientation sensing ;)It is detecting up side down
I think I´ve seen some of these bulbs before, years ago in controller boards for model submarines. I think these are half fluid filled with sensor wires for tilt sensing. In an autopilot they could be used for gravity vector sensing...
That was the time before cheap MEMS..
Here is some reference: http://www.ferret.com.au/c/Bestech-Australia/Dual-axis-electrolytic...
We had one of these, what an utter nightmare to set up...It took ages to get a presentable flight from from it, did work in the end (being noobs with it didnt help either...)
Im glad things have moved on some...lol
What a great share!
Like MarcS said, It's an electrolytic tilt sensor.

@Gary relax, it cannot be that old. As I remember those were the days when GPS was already coal-powered, wooden solar cells were already a thing of the past and a subject of many jokes among those in the know.
