I always use AirEd for airfile tweakage...it's logical to want to use the actual (or perceived) values where these are available, e.g., drag coefficients, but I found that it is better (for me anyway) to test and retest the aircraft, adjusting the figures gently until something close to the desired effect is found. For my own concept aircraft, I had originally  entered all the "proper" lift and control surfaces carefully calculated with respect to the aircraft's design, and it wouldn't fly, despite having a configuration similar to any other modern combat jet. Lack of FBW may have something to do with that...anyway, getting back to the start of this reply, I found that a noticeable (although not powerful) effect with gear drag was achieved by entering a value of 102. There is also an entry available for gear pitch effect under the same section (1101). Also, changing one entry often affects others, so it may be necessary to modify one or more other items in addition to the one you are trying to correct. Good luck

I tried that entry in AirEd and it had no effect.  With AirWrench the aircraft flew like shit, So I want to stick with the Air File generated with FSEdit.  But, is there any way to add Gear Drag in the CFG File???

It really sucks that Microsoft People are not involved in this.  It would be easy for them to bring out an updated version of their editor.

Harold,

FSEdit is one of the worst pieces of FS software I've ever come across! I agree with CAFedm and have used AirEd for the last few years and would recommend that you stick with it.

The following might help you with setting the gear drag setting. If you look in section 1101 Primary Aerodynamics, you'll see a number of different sections: the first is Misc., the second is G limits, and the third is Drag. The third entry in this section is for Landing Gear, which for my FD for the 737 Experience I set at 66. To give you a feel for other settings, the default FS9 Cessna 172 has a setting of 14 and the default 747 is set at 51.

My advice? Double the landing gear drag figure until it makes a noticeable difference, and then tune from there.

Which plane are you trying to modify?

Harold, I know what you mean about AirWrench.  I bought it myself, and then figured out a glitch: when you load the aircraft into AirWrench, the program adjusts it so that all factors will work in harmony, instead of some parts conflicting with each other's readout.  I still haven't figured out what parts conflict with each other, but my model seems to have evened itself out.  If I were you, I'd stick with it and see if you can make AW work.

The aircraft I am trying to modify (actually still designing) is my own design, the HD

With the spoiler, etc, you're gonna need XML programming with gauges on the panel.  That's the only way of doing what you're talking about right now.  As for opening spoilers in increments, if you include a lever in the VC for spoilers, people can adjust them as necessary.  Program the spoilers themselves to pop out at the end of the animation sequence (about 76-100 frames), and everything else to open and then close in increments just like that.  (0-25, 6-50, 51-75, etc)  That will take care of the visual issue of that, and the spoiler effect will increase the farther they move the handle.

Harold,

I'll download the plane, have a look at the FD and see what I can suggest.



EDIT: Just had a look, and tried a few things. Sorry, but I agree with the others who have suggested that you reduce max thrust. Biggest issue is that it has such a high thrust/weight ratio that even with the ground brakes on at idle, the plane still moves forward on the ground (you can almost hear the tyres squealing!) You can even take off at idle with only a burst of throttle to get the ground speed up, and then reducing it again. It will climb at idle thrust, at around 2000 fpm! In level flight at idle thrust, the speed stabilises at around 340kts, so it's no wonder that you're having to use extreme drag to slow the plane down enough to land it. I'll have a play to see if I can come up with any suggestions. (I like the pilot's see-through shirt, however!!)
