Having problems calibrating an airfile with a new Gmax model in FS2004.The aircraft.cfg has been set up with the correct contact points, fuel tank locations, root chord etc. However, after modifying the aircraft.cfg file so that the airfile and visual model work together - the aircraft now oscillates in yaw and roll when in AP HDG HOLD, or at high speed.Might this have something to do with Wing_Apex, or Wing_Sweep, which have been altered to gain a correct CG?Thanks in advanceAsh

Hello Ash,Does bump mean something? The FS9 AP is crap and needs a benign aircraft for it to be much use. This was discussed on AvHistory/Decode ForumQ: "The FS2004 aircraft I have designed (if you call copying an existing aircraft, designing...) flies absolutley fine at all altitudes, and has been modelled on real world weights, surface areas, thrusts, speeds, and other figures I have come by from various sources including the pilots manual. At the moment the only part of the flying it doesn't want to do is follow pitch or altitude hold set with the autopilot........ She flies heading fine, but not pitch.... any suggestions on what could be the solution? I've tried editing the trim factors in the cfg to try to identify the problem.....In the air file the autopilot is set to follow pitch...?"
