spectrum radio question
hello all, i have a new specrum 3 channel radio. i have had nothing but problems with it. it will not stay bound. i follow the instructions to a T. the radio works from 45 sec to a couple of minutes, however, the receiver light goes out and that is the end of communication between the rx and the tx. i have tried with both nicads and dry cell. i also, have tried with the sevos pugged in and unplugged. always the same results. i have sent the radio to horizon, they updated the software, but found no ther issues. straight out of the box and into the car and the problem is the same. the radio is brand new. is there anyone out there with a similar experience. any advise will be greatly apreciated, thx barry
