Hi Iain
Any chance of Scotflight for ORBX installers for P3Dv5, had not intended to go for V5 with FS2020 potentially on the horizon, but only went and done it, it should not need much if any work scenery alteration wise, have all my ORBX installed into P3Dv5 now and would switch from P3Dv4.5 to V5 in a heart beat and uninstall V4.5 to save on disc space if I could still have Scotflight.
Apparently ORBX scenery's needed little to no work to be V5 compatible, Aerosoft seem to be saying the same thing.
Cheers.
Colin
