In another thread, we have been discussing a find on e-bay. There are multiple listings at various price/shipping cost combinations that are selling Buy-It-Now AR6100 receivers for around $18 to $20. The AR6100 is no longer sold by Spektrum, as it has been replaced by the AR6110, which sells for around $50.
I have purchased one of these cheap Rx’s and tested it. It works fine. At least as good as my other Spektrum RX’s: AR500 and AR6110.
So, today I get an e-mail from ebay stating that they have removed the listing because “In this case, we removed the listing because the copyright or trademark owner of this product reported that they believe the item may not be authentic.” I just checked ebay and there are still many listings on-line for the same price.
I did and do have some doubts about the authenticity of this product. Others have stated they may have been removed from helicopters that were upgraded to the newer RX’s. It looks just like my AR6110; all the markings are authentic looking. Although I noticed this one states it is made in China, and the AR6110 and others are made in Taiwan.
