@ErikU Did you get it working with P3D4? During Installation I get couple of warnings of incorrect dll version, and that SP1 would be needed. In the Sim itseld, No FLT gauges are shown.
(Since Just Flight Put an HSI only in the MSFS Arrow, not in the P3D, but I cannot use RXP GNS on MSFS, for reasons, I want to try to at list put a 2D HSI in the VC over the CI in the Arrow...)
