Digital Servo
So the fact that my radio is a little aged, means there is no incompatability issues. I guess I wasn't sure if that ment it needed a digital signal from the radio/receiver. (I currently have a bb, metal geared servo from Hi-tech) I'm not extreamly happy with the hightech as there seems to be (has always been) some slop in the arm movement. I think I paid around $56.00 for it.
