July 9, 20187 yr Hi Guys: I have the flysimware Beech 18 and Milton Shupe's Beech. I compared the fde entries for these two planes and the Caranado Beech 18, and searched the internet for additional info on the Beech. I made some changes to the Carenado fde, and it flies much better now. I don't have a lot of knowledge about fde's, but the plane is no longer twitchy and a lot more stable. I'll share my changes after I find out whether this is proper. Mike Gutierrez, North Hollywood, California. Michael Gutierrez. North Hollywood, California
July 9, 20187 yr Anything to deal with its fighter-aircraft-like agility at the moment... thanks for looking into this - what were Carenado thinking of? A Edited July 9, 20187 yr by aentwis Andrew Entwistle
July 9, 20187 yr Tailspin45 is a real world twin beech pilot he’d be a good tester for this FDE if you wouldn’t mind sharing your changes Id love to make the beech 18 actually fly decent ATP MEL,CFI,CFII,MEI. Type Ratings B-737, ERJ-190,ERJ-170
July 10, 20187 yr Author I sent an email to Carenado asking them if I could post my changes. In the mean time, if you sent me a message, I will sent you a text file with the changes I made. Mike Michael Gutierrez. North Hollywood, California
July 10, 20187 yr Gulp, I hope they say yes. I posted mine elsewhere here already. Don't see where it's any different than creating a repaint. I'm not selling the AIR and CFG files, after all.
July 11, 20187 yr Author I asked Carenado if I could post my changes, but they answered by merely thanking me for my feed back. So, here are the sections I changed in the Beech 18 FDE.

July 12, 20187 yr That's not the FDE, that's the .CFG file. The guts of the FDE is in the .AIR file. It requires a reader program to see and change. (AirEd.exe/freeware)

(AirEd.exe/freeware) That's incorrect. A lot of important info is in the cfg file. The FDE consists of both files. However using an airfile with a different cfg file is usually a very bad idea and in case of the above 'modification' the D18 is way overpowered, untrimmable at high cruising speed, the props are located well ahead of the whole a/c etc.
