So just got an XLX2 for my DBXLE and I'm calibrating it and throttle calibrates fine but as soon as I get to the brake portion it flashes red and beeps constantly, I hold my brake full and it just keeps beeping and flashing red. No trim is set on my transmitter and brake is set to 100% on my DX5 Rugged. I tried rebinding and I was able to bind to the receiver fine and it registered full brake. Not sure what else could be wrong.
