Most all our current electronic radio stuff are very reliable and have an extremely high effeciency rate, but unfortunately not all will give a warning that something major is about to take place, however there have been quite a few lucky ones like myself who do get a second chance. If yours is working okay and you have not crashed your model then more than likely there is nothing to worry about as in my 30 years of R/C this is the first Rx ever to give a problem.
