I believe the main differences between Fanda and Majestic are just that the visual model is different and I'm not entirely sure if the FMC is completely functional in the Fanda one. Besides that all I know of is that the panels don't pop up as the right size in the Fanda Dash-8 from my recollection.

If you want a fairly nice visual model to go with the Fanda version of the dash 8, you can go with the merge for the Dreamwings dash. You could find it in the avsim library or google. Try a search for Dreamwingsfanda merge, or something like that. It does exist, just can't recall exactly where to find. Myron P
