The reason I brought this up is because wing flex is not new. PMDG, Captain Sim, CLS, AeroSim, Overland, Sky Simulation, Ultimate Airliners - just about all these add-ons I have feature wing flex. My observation was that the amount of wing flex was not intense enough. Of course this feature comes with the sacrifice of not being able to use shockwave light on them realistically. Also, the "engine exhaust" effect can already be added to just about any A/C's with Nick utility. IMO, I think all these "eye candy" features are quite entertaining, especially on long flights - Perhaps you can go back to the cabin and watch a movie As old as FSX is now, I am still being amazed by what developers and programmers are doing to make FSX what it has become today. Happy simming . . . . . .

Ridiculous amounts of wing-flex -> http://www.youtube.com/watch?v=Dscn0rFvukg

...I've noticed that most A/C's have flexing wings. I have also noticed that they do not flex nearly as much as in real life.

I had the opposite problem with the DG808S sailplane. The wings flexed too much compared to the pics of the real thing on DG's website. I tried changing the modeldef file with no effect... found out it was because the values are compiled into the actual aircraft model files. I tried hacking into the model files with a hex editor, searched for "WING FLEX", changed the text value corresponding to Scale from the original 0.5 to 0.2 in two places in each model file, and now I've got perfect wing flex. The wings flex appropriately at higher speed, when you change the flaps (which changes lift), and during maneuvers and turbulence. The ailerons/flaps animate and flex correctly. The text looks like this: WING FLEX PCT:1#percent#0.5#50andWING FLEX PCT:2#percent#0.5#50 You'll have to change all the model files for that aircraft. If the wing flex seems too low, raise it a bit and test. In this case, changing 0.5 to 1.0 would have doubled the amount of flex from what I'm seeing. Your value may be different from 0.5... for example if it's 1.0, change it to 1.5 and see what happens. If it's 0.5, change it to 0.7. The 50 should be the same, it's 50% of the flex from minimum to maximum, the same wing position that shows on the preview animation in Free Fight when you are selecting the aircraft. Warning: MAKE BACKUPS. Do not add or subtract characters when hex editing, only replace them. This won't work in Notepad because it changes some characters. I used the hex edit function of the free download Notepad++ which has replaced Notepad for all my text editing needs... XML files are much easier with syntax highlighting. :) Hook

Just a followup on this. I don't know if anyone's reading it, but it might help someone who found this thread by a Google search, which is how I got here. The pertinent lines in the modeldef.xml file (in the SDK) are: <Variable>WING FLEX PCT:2</Variable><Scale>0.5</Scale><Units>percent</Units><Bias>50</Bias>This corresponds to the text WING FLEX PCT:2#percent#0.5#50 In the aircraft's model file. The scale parameter, for the purposes of wing flex, determines the "stiffness" of the wing. A lower number will increase the wing's stiffness, so it won't flex as much. A higher number decreases it, and the wing will flex more. The line in the model file is read by a text interpreter, and the interpreter doesn't require a leading zero before a decimal point. This means that you can change #0.5# to #.25# and it will work just fine. Hope this helps someone. Hook

I think they have got the amount right, its is just not very realistic. It seems to jump from one position to the next without the smooth motion.
