This one very impressive layout and John the builder surface mounts his servos as I'm doing and connects his operating wire in such a way as to give some slack. I'll take a photo soon of my copy of his elegant solution. Here's a photo of board 3 almost ready for sleeper laying to commence with the servos just laid in their approximate positions. They are under the platforms mostly or the road bridge. Kind regards Andrew 2787_271847_410000000.jpg posted: 28 Oct 2018 00:40 from: Andrew Barrowman Sounds good Andrew. I like the fact that you are mounting them "topside". BTW, the more slack you can put in the connection the better. That will increase the servo rotation which will reduce the tendency for the points to back-drive the servo. Ideally you'd like the servo to rotate through something like 120 degrees. I believe the latest version of the Megapoints controller stops sending pulses after a second or so. That reduces the probability ...
