FOENIX FMX - (RevC4A) - General Technical Information

[stef]

Good Day Everyone,

For the last couple of weeks, the release of the early-birds has begun. Up till now, most of the information was shared on Discord where all the early-birds were invited. Now, that we are moving forward with the release of around 40 Units. More and more information will become available.

I will urge people to not post in this thread. If you have any questions about the information posted here, please start a new thread so the old Alpha members and the new Beta Members can help answer your questions. It is really about sharing the most information. Slowly it will be transported into the Wiki.

Thank you

Stefany
