I'm at the doodling and head-scratching stage with some aspects of the next build, and one of these is a small gun platform. I'd like to be able to throw the flaps or gear switch on my TX and thereby make the platform rotate fairly slowly back and forth through an arc of 90° or so.
Given that I have only hand tools and am on a very limited budget, I can't see me doing it with a motor and a geared / mechanical drive, so we're talking servo here. Can I slow down a servo electronically without a major loss of torque? How do I do the continuous cycling from end to end of its travel? Or am I barking up the wrong tree altogether?
Anyhow, following on from that ...
Where do I find diagrams for circuits to do useful things like control servos? All I've found so far is diagrams either for ESCs, TXs, RXs or lights or ones involves programming chips (which it outside my experience). I'm hopeless at electronics theory but I have a work history in PCB and PA amplifier assembly so I'm perfectly at home with a soldering iron, Veroboard and components - but where on earth does a chap find useful circuit diagrams for modellers?
