i had a similar yet not so similar problem, i had problem with one of my spektrum receivers. the internal antenna came off, i could have soldered it back but i didnt want to mess with it. anyway i bought this extra receiver with out the radio on ebay and could not prove a place of purchase cuz it was off an auction, well i sent it out anyway and told them that i didnt have a receipt. about 2 weeks later i get a package in the mail from horrizon, and it was my receiver looked the same till i openened it and bam the antenna was fixed. to top that off they even changed the upper circuit board. best of it all i wasnt charged. Talk about customer service. i love this product.
