Reverse engineering a low spec servo isn't always the best start but it's where info and diagrams and demos could help. I often come across reply posts on why this'n'that won't work from folk who don't know how electronic rc gear, like a basic servo, works at the component level.
I've taken a standard, quarter turn Futaba servo to slow it down, increase the travel beyond 180 degrees, reduce and increase deadband and so on. I can tell you
this doesn't work well because the deadband, hence controllable resolution, is ten times that of its quarter turn equivalent. Geoff's observations would be shared by anyone who uses the same servo out of the box. The 2 turn servo will work perfectly well as a budget price, low spec sailwinch but is worse than a quarter turn servo to reverse engineer into a turret mechanism.
... i was just goin to have a servo push the turret left an right but im not happy with that idea be much better with a motor turning the turrest but i need info so any ideas an diograms ?
So what's the specific problem that makes you unhappy with the idea?
Each way comes with its pros and its cons.
