I lost 3 planes flying with a DX7. Sent pics to horizon (of my set up) along with the radio, recievers and all the data I had collected saying that my batteries and switches were good. And they agreed that they were good. I even asked horizon if they wanted witness statements from a very seasoned veteran
2.4 spektrum pilot who has had no problems. He was there helping me during 2 of my losses. I'm not bashing Horizon. They are a good company. BUT they said they could find nothing wrong with my systems or set ups. I asked if there was anything that would cause the problems that I had they simply said "we don't know". I now fly Futaba 2.4. Haven't had an issue. I'll drive a Ford or a Chevy depending on which one satifies me the most. The same goes for my radioes. I don't bash Ford when I'm driving a Chevy and I don't bash Chevy when I'm driving a Ford but both have had there problems over the years just like Futaba and JR have. Needless to say Spektrum may have a problem judging by what's going on at flying fields. Futabas overheat but Spektrum still has no solid cause as to why people are losing signals.
