Hi folks,

some advice welcome here. My son's RR decided it would just not switch on when he tried to do so for his second or third main during raceday yesterday. It would just do a tiny "blip" sound then nothing else. We ended up quickly binding the rx to his former, and now back-up EX-II KIY (not RR) tx so he could finish raceday, but this was planB... (and this is why I ALWAYS carry a spare radio when going to race...)

I checked the obvious and this is not a power supply issue ( I switched the power supply from one EX-II to the other and it didn't change anything to helping the RR turn on or prevent the KIY from turning off). As far as we know, the radio didn't get dropped or hit anything. I jiggled the screen and the mechanical radio modules but to no avail.

Any suggestions welcome. Thank you.

Paul
