I purchased a used programmer a month or so ago. I also purchased 6 new digital servos (HS5645s) in January 2006. I was told by someone at Hitec that I could use my programmer (V1.03) to program the old servos and the new 1.04 servos. I had some trouble yesterday programming one of my servos, so I called Hitec again and spoke to Marty. He said my V1.03 programmer will not work with the newer servos. There is informatoin on the forum that says the V1.04 programmer is backwards compatible to V1.03 servos. What happens when you program a 1.04 (new servo) with a 1.03 programmer? Can someone sort this out for me?
