Yes, I have tried it. I have mixed feelings about it as I expressed in a totally separate topic.
Anyways, the biggest issue I had with the mod was that there was a very noticeable FPS drop when running it. While using the default A320, it ran perfectly smooth on my PC at high settings. Even at larger airports like KLAX, KDEN, KSFO, KEWR, etc. I was having no problems. Maybe there was the occasional stutter, but otherwise it was fine. With the FBW mod, I was suffering FPS drops at small airports, which was very frustrating. I even tried everything I was told to gain FPS back and it was still bad, idk why. I have a good PC, brand new in fact and other than MFS, completely clean.
Also, even with the latest dev version, I still experience AP issues. I thought the FBW mod was supposed to fix that, but it still gave my issues. It would bank left and right 30 degrees in flight when I engaged the AP. Also, it swayed left and right in flight which the default A320 finally stopped doing after they fixed it. Overall, the FBW mod didn’t blow me away and I ended up deleting it. I ultimately decided I’d rather have high FPS even if I have to use the basic, default A320. I have to say, it was working really well for me before the USA update. Hopefully, the AP on the default A320 will be fixed soon to the way it was prior to the USA update when it completely broke, leaving it unflyable.
