Did you ask for their return? My ST-126 was defective NIB. I sent it back to Horizon within a week and they forwarded it to JRSA. After several go-arounds they (JRSA) offered to return it "as is" but requested $ 7.99 shipping. I then asked for a mailing address for sending them a USPS MO for payment. This was in early Sept and have not heard anything back from JRSA. Not a good example of service from their supposed service center. I wanted the servo back for installation/sizing, servo arms and the lead. Still waiting....
