Colin if you use servos what controller are you going to use and how do you plan to run them.? Analog or Step/Dir.

I don't know i will need to find out. Do the cheap Chinese controllers do both methods?

No, not normally.

Step / Dir is common. Analog, less so.

Can't answer that because depends how cheap your talking. If you are talking the Newker type then I think most of them have both but if you are talking the really cheap Chinese controllers then no most will only be Step/dir.

However, my main reason for asking this question was more to find out if what you plan to use will provide high enough frequency that you can get the full resolution and speed from the servos. Asking about Step/Dir was to get an idea of how hard or easy you are going to have it to set up the servos, esp if using the cheap Chinese servos which don't offer any help with motor tuning.
