I have a Clark TK22 (I believe) or a TK20 not sure how to tell the difference. I would like to know if anyone has connected it to a Tamiya rotation servo (from Abrams) and if so how would you accomplish this? I am making a static tank full function RC and I already have the Clark board for an Abrams so that is what I am going to use. There are instructions online to make the board use an elevation servo and to make the recoil unit work with a servo but not sure where to connect the rotation unit . Thanks any help is very much appreciated , Jim.
