I mounted my Spektrum AR7300BX flybarless unit in my E5 with both the antennas mounted away from the carbon fiber, one vertical and one horizontal facing the rear of the heli. My question is do I need to run a satellite receiver with my existing two antennas? I know that it helps with signal strength when the heli is in certain positions but I am not a hard 3D pilot. I will be using my existing Spektrum DX7 with the flybarless unit. Thank you to everyone with your input on this subject.
