It isn't pure fadec as the purists would dictate but it is still fadec.
I assume you are talking about the 407 old style single FADEC. The sloppiness of the governing when the primary channel reverts is dangerous. It’s already a bad day if you get there, but it’s not something you want to fly with for long. Comparatively Easy to over torque or under speed. There was a period of FADEC issues on 407GX’s during the early years with the G1000 that put a number of pilots into manual mode due to corrosion on the FADEC connectors.... wasn’t good. A dual channel is simple to do if you plan it from the beginning... harder to add later in the life of an engine.
