October 24, 200322 yr On this add-on a/c I have, the SPD/VS function works a dream; but the FL CH function is unstable in that it cannot keep the commanded IAS. So the a/c trims and re-trims itself all the time on AP and it porpoises up to cruise and then plunges down at an insane VS on descent. The AI arrow chases the FD arrow all the way up and down in climb mode.Is this a gauge issue or a .cfg file issue? I mean, can I go into the cfg file and correct a certain parameter for the trim?Appreciate guidance, thanks!JS Jonathan Sacks Dell XPS Gen 4, Pentium IV Northwood extreme 3.8Ghz, 3Ghz RAM, eVGA 7900 GTO, 12 GoFlight modules plus MCP-PRO AP and EFIS, GF pedestal, CH rudder pedals, CH throttle quadrant, 42" LG LED, 24" DELL LCD, Windows XP, FS2004, FSUIPC 3.96 FS Autostart 1.1 (Build 11), FS Navigator 4.6, UT, FE, GE, REX, PMDG, Level-D, PSS, etc.
