I have a J.R. 7 radio with A.R.7000 receivers and have been happy with the gear.
But recently I have "lost a couple of planes inexplicably, and occasionally we hear of problem sets. It has been rumoured that this model was prone to a problem that has been resolved. This equipment is now 3 years old, what problems If any were there, would my set be included in the problemed production run, and what can be done if necessary to correct them?
I need an authourative answer, as I don't normally respond to rumoured Information.
