From the
IFI FAQ be careful when using this year's radios with older robots. Since they just released
v14 of the master code with the most recent FIRST bulletin, you may want to use that for any older robot controller tests. It's not clear they've tested v14 with any older RC's, so if there's any trouble try using v13 instead.
Which IFI guy did you talk to?
I wouldn't assume the radios have an issue until you've used this year's controller with them, and the v14 update. IFI is turning our radios around in 1 day, so you've still got time to get them repaired if necessary. Using last year's radios with this year's controller also works perfectly fine.
