I need some help with a way to connect the wing servo arm to the inner cable of the aileron snake. I've been stuck on this for the past month and still haven't found a solution.
I've considered all sorts of solutions involving soldered piano wire but I cannot think of a secure way to then connect the piano wire to the servo without excessive play.
I bought some push rod retainers from Asia, and after waiting a month, I found that they are too large. The push rod hole is 2.1 mm and they are quite large all round. I've since discovered that they do have some 1 mm retainers but they still look a bit bulky. Maybe this is the best or only solution?
So, what's the smart way to connect the servo arm to the aileron cable?
