So I sent Mike Reagan an email and he confirmed I can try the odyssey board in any odyssey loc. So after replacing both fets on the board i tested it in another loc and it works! Both directions are working.
So the question now is, do I plug it back into the gg1? I still dont know why the fets blew in the first place. The thermal pads look good which insulate the fets from ground. I'm thinking of pulling the motors out and testing them with a 9 volt battery to ensure both directions work. After that I think the only things to check are the radio board and the bridge rectifier.
