Merge it like you would every other aircraft BUT use the PMDG contact points instead of TDS, not sure why but mine bounced like mad on TDS ones so I put the PMDG ones back in and it's ok, you can see it's a little bit under the surface but no biggie.@jackralston:
How did you do the merge? My aircraft just bounces on the runway.
> Make new folder
> Copy Panel folder, .air file and aircraft.cfg file into it FROM PMDG (rename the TDS .air file if you want to NOT use it and make sure the PMDG air file matches the TDS one)
> Copy the TDS model folders into new folder
> Copy the EXT_TEXTURE_ANIM, TDS_UTIL, TDS737ADVCONTROL folders into the panel folder
> Copy the vcockpit entries from the TDS panel.cfg into the new panel.cfg (also can put the window entries for Debug and Util at top)
> Copy aircraft textures folders into new folder
> Replace [fltsim.x] entries in aircraft.cfg with the TDS ones, also replace the exits, effects, lights (from PMDG)
Works well for me, cannot wait for the 800!
