I've got a problem where my Granite BLS seems to go out of radio range when it's only 50-75 feet away. It wasn't like this at first, and it's really annoying. I used to be able to drive till the truck was so far away I could barely see it. I've tried new transmitter batteries and made sure I have fully charged packs. I've also tried rebinding the receiver. I should mention that I replaced the ADS-5 servo with and ADS-7M. Also, when my son's Fury BLS started having weird issues, (lack of steering, random throttle changes, lack of range), we did some troubleshooting and narrowed it down to the ESC which Arrma replaced under warranty. One of the troubleshooting steps was putting my receiver in his Fury. I'm worried that either I caused damage to my receiver or perhaps my ESC is failing now as well. Does anyone have any additional troubleshooting advice? I figure I will end up calling Arrma for warranty again at some point, but I want to make sure I show due diligence and ask for the proper parts.
