I own a DX7 and also have an JR10SXII which I converted to DSM Spektrum 2.4 . Other than the one misshap this past summer with the 10SXII and loosing a plane, my DX7 has performed without any problems. Horizon gave my 10SXII a clean bill of health and I'll be putting it back into my next monster or Giant scale project. I'm also saving up for a DX8 I like the telemetry to monitor the airborn battery pack. John T
