I also said I would do some further checking comparing fades to the other 3 receivers.
Lastly not sure why the snide follow up remarks remarks. If you were so bothered and or had something positive to contribute you shouldn't have responded in the 1st place.
Well here is where you are wrong assuming that I do not know the Spektrum systems. First, by mentioning that you have four satellites or remotes as Spektrum prefers to call them now, that you have a PowerSafe rx of the older style.
Second, higher channel count rx will function with only three receiving units be they remotes or built into the main unit and you must use the "A" port if you only use three, or it will not function. All the upper channel count rx's require three RF sections; some have two in the main unit, some only one and those must add the required remotes to make three total.
Third, once turned on and linked, the system will function on only one RF unit until it is shut off as a safety feature.
Fourth, while I cannot quote chapter and verse right now, IIRC the max length on a remote lead is 48" not 36". I suggested using the extension which splits in two halves allowing the use of a regular servo lead which has larger wires and thus less impedance.
Bye the way, you spelled Spektrum wrong.
