I've got several of the GWS 8 Channel Dual Conversion receivers and have used them in several contests and funflys and have never had a problem. IMHO they are the best receiver out there for the price. I did have one busted in a crash. It was way past warranty stage but I sent it in to Horizon and they sent me a new one at no charge. Can't get much better than that. BTW they are just a hair bigger than a Hitec 555 and I would guess about the same weight.
