What I want is to design my own system for R/C use but I don't have much time for hobby now, so the project is dormant. Besides, as I'm mostly a digital guy, I'm struggling with the filter part. I can calculate and design active filters, but I'm not sure what are the necessary parameters for them, and I don't have time to do much experimentation. Perhaps we could cooperate in the design.
