Hi, I have just bought an old, but unused, Ripmax Autopilot. Has anyone on here ever used one or know anyone who has? I bought it at a tabletop sale just recently, as usual with me, out of curiosity/ for a laugh. Anyhow, before trying to fit it I wanted to know whether it is compatible with my Spektrum 2.4 ghz radio. There is no mention of Spektrum radio in the list I saw, but then as the last manufacturing date appears to be 1996, perhaps that is not too surprising! If anyone knows anything about them, and any problems/ benefits, don't be shy, let me know. Dave
