Those were the days. When your transmitter only had one button to press, and your biggest problems were

- did you wind up the escapment enough.
- was your last command left or right
- can i press the button for a short enough time to blip the engine shut
- do I have enough juice left in the batteries.
- will the glue set in time for another flight. [&:]
- is the valve/tube still glowing

Thought some of the more senior members might recognise this technology from the early 60's. I suppose the clockwork escapment was the first digital servo. well you needed your fingers to wind it up.
