Guys, the way I did it is this:
In the "keyframe animation" table in FSDS2, there are two entries called "l_spoiler" and "r_spoiler". Just tag your parts as that, and have Keyframe 0 as the "flush" position, and Keyframe 100 and the deployed position.
Compile your aircraft and start up FSedit. Go to the Flight dynamics page and click the "controls" tab. In the bottom right hand corner there is a section called "spoiler".
Check "spoilerons available" and set the max deflection of your spoilers.
Save and close FSedit.
Now located the aircraft.cfg file and open it up in notepad. Under the section marked "Aircraft geometry" there will be some lines like this.
spoiler_limit = 60.000
spoilerons_available = 1
aileron_to_spoileron_gain = 3.000
min_ailerons_for_spoilerons = 10.000
min_flaps_for_spoilerons = 0.000
If not, add them in. The values are self explanatory, except for "aileron to spoileron gain" This basically means (if it's set to 3, as it is here) That if the max up limit of your AILERONS is 20 degrees, then to get a 60 degree deflection in the spoilers, the ratio must be 3:1.
These numbers are a good start, but play around until it looks right for you.
Hope this helps you guys out, any problems or questions, just post them and I'll try to help!
