HS-5485HB Problem
Was setting up a new plane with a Futaba receiver. Initially installed a couple of HS-5485HB from a previous plane, but they would not operate properly. They would twitch a bit, then nothing. Thought it was the receiver so switched to another one. Same problem. Hmm. Took a new servo out of the box. Still nothing. Transmitter? But wait. The 225MG servos were okay. Plugged the NIB 5485 into the HPP-21 servo tester. No sweep!! But the 225 in with it worked fine. Plugged in the 5485 alone, pressed Refresh and the message came back that a digital servo was connected, but still the servo would not step or sweep. Same problem with two more NIB 5485's. What's going on?
Of course Hitec is closed today. Anyone here have suggestions (other than Buy Futaba!)? I've used Hitec servos, including the 5485, for years with nothing but good operation.
