I had a Ham IV rotor that was reliable for years. It survived lots of storms. Suddenly the little nose piece snapped off. I took it apart, got a part number from someone in this group, but then I changed to a "Tail Twister" and have never looked back.
Other guys I know hate the Hygain rotors, and swear by the Yeasu Rotors.
Some guys drive Fords, Some Guys drive Chevys. The Hygain Tailtwister is working for me.
OH. You;re asking about the control box inside the house? Heck, I'll give you one of those.
