Okay I've got to finally admit defeat Embarrassed

. I'm helping out with a swingwing model, and I want to know how I can get the wings to change position automatically in the .cfg or .air file.....
Any ideas anyone?

Cheers
Ozzy

Ozzy, the only way I can think of is having lots of sets of wings at incremental degrees then a set of conditions applied to each wing so that say for example

if airspeed greater than 210kts and less than 215kts then show 60 degree sweep wings

if airspeed greater than 215kts and less than 220 kts then show 65 degree sweep wings

etc etc, the more sets of wings you have the smoother the animation, but it could work.

And obviously you could specify all sorts of variables other than speed such as altitude etc.

It could be done with a custom guage controlling an animation....but in the .cfg or .air?

Good luck!

I am curious why one could not use the pct_ flaps tags for this. Since flaps are deployed at progressively slower speeds, these tags could be used to swing the wings forward at slower speeds in prep for landing. Just a thought.

You could, but wouldn't you also want a way to swing the wings on low speed cruise, without operating the flaps?

There's a series of postings in the FFDS forum (Tips Topics) by Dennis Simanaitis on speed based animations, this could provide an automatic control of the animated wings.

Well, with the new gmax SDK one could create custom variable for wings animation and trigger it to airspeed - so it will change wing position automatically, or create a gauge or 3D lever to control this wings position variable manually. It is rather easy nowadays. One question here - how to change FDE behaviour accordingly?

What do you feel when you crash another aircraft?

A custom guage can control the flap position. Use that and the fde is affected as you would expect.

Hello Ozzy,
it would be nice if a gauge could switch cfg and/or air files for each wing angle as the aerodynamics for each is quite different and would need a new air file. But, is that at all possible....?

Hi Ozzy
Ok assuming its for fs2002 or fs9
I would use the concord nose animation,I used it for my gear doors on the mirageIII and works a treat as there are no screen message

then build a xml gauge using speed and the INCREASE_CONCORDE_NOSE_VISOR
DECREASE_CONCORDE_NOSE_VISOR
have a look for a file called xmlgau01.zip by Arne Bartels
it has a heap of good info on xml gauges and events.
I'm not sure but there maybe some drag related entry's in the air file for the concord nose if not you can always model in flaps and spoilers through xml gauges.
Regards
MaV

Hi guys this is an FS9 Gmax project (top secret, hush hush).
I'm still conducting experiments at the moment, ideally I'd like it linked to speed... This is causing a few headaches at the moment. I'll just have to continue headbutting the keyboard Wink

Thanks for the input Wink
