Letting veteran teams use old radios should be allowed in this situation. FIRST is all about sharing and caring. I am sure it wouldnt be unfair for teams that dont have access to them because others would share during the matches.
No one would blatently let a team suffer because of malfunctioning radios.
This would actually help IFI with the demands to fix the new radios.
Even though ours works now, I am still advocating for others.
