RE: Spektrum DX-7
most failures are owner caused -
the incidence of failure in electronic products is extremely low -being waaaaay under 1% in most consumer stuff
Once the electronicss have been thru initial period of run -they typically will run forever
however th older stuff with lots of coils and and discrete parts -really did age and needed perking up from time to time
the basic design of the Spektrum RX is simply-a chip - this type technology has extremely ow incidence of failure -once setup (programmed) .
many failures(?) I have read about on the TX of the Spektrum are again owner induced -
Of all the Spektrums here - no failures.
The stuf on 72 --well again most dumb thumb stuff
