Where can I buy a certain nighthawk pro circuit board?

Hello, my good friends drone's circuit board died the other day and we can't find the circuit board anywhere. I was hoping as a last ditch effort i could ask here and hopefully find the piece....It's a night hawk pro 250/280 class fpv racer.It's a long shot but I'm hoping this could work. If it helps we are in Canada. Thank you! via /r/fpvracing https://ift.tt/36tvcjq
