Picked up a very used Cirrus 4 channel PCM radio last week. The throttle servo keeps returning to neutral position after about 40 seconds. One of the radios features is that the throttle cuts back if signal is lost for more than 2 seconds. I doubt it's losing signal as I continue to work other channels. Where can I get more information on Cirrus? Does anyone still service Cirrus radios? Any chance that it is worth repairing?

Any chance I can simply replace the receiver? What options do I have?

Thanks
