My observations so far.
Carenado C185 good. Not installed the others yet but assume they'll be OK
FTX Global FTX PNW fine
FTX PNG had to manually add it via the Scenery library after installing
The bad news for me
GoFlight modules GF 45, RP48, GF P8 not working. Showing up in Windows Devices and GF software pointing to correct location
Saitek Switch Panel not working. Installed drivers and checked test function all ok.
Clean install W7 64 bit no previous versions of FSX on my system, just the SE edition
Sorry if this has already been covered guys but have done lots of googling before coming here.
Oh, the sim is super smooth BTW
Cheers
