Quote from: pooh on October 29, 2020, 14:22:20 pmThe Elmic used a rubber band, twisted, to provide the force needed to shift the rudder (single channel only, transmitter on or off) Every "on" blip of the transmitter caused an electromagnet to release the motor shaft, and an escapement (like a clock) allowed only 90 degrees of rotation for each blip.The rest of the mechanism moved the rudder from centre, to left, to centre, to right (can't be sure which way round it went but you get the idea)So if you were going straight and want to turn left, just one blip. If you wanted to turn right, you blipped again to get straight on, then again to get right. You had to remeber which "straight on" you were in to know how many blips got the desired result.
Quote from: pooh on October 29, 2020, 18:00:36 pmIIRC then came multi-channel, using tones to control the individual servo channels? I seem to remember a bar-shaped electromagnet with a sort of comb above the long narrow core, so the "teeth" vibrated as the tones were supplied and the one at resonance moved the furthest and made contact electrically whilst the others didn't make contact.Or is that something plucked out of my demented memory?

Quote from: Brian Cooper on October 30, 2020, 06:59:54 amI can fly both Modes but I have a very heavy preference for Mode 2.I tried Mode 1 for pattern flying but found there was absolutely no advantage in separating the ailerons stick from the elevator stick. I flew smoother and with more precision on Mode 2. Each to their own way of doing it, eh.
