Also something to be aware of with tri-jets (DC10/MD11 as well as the 727) is that some models only have 2 of the three engines active. If you alias a four-engine panel like the 747, you can immediately see how many engines there are, by how many throttle levers are working. If two, it is possible to add a third engine by editing the .air file (use AirEd) and then the aircraft.cfg (use Notepad).
There is a very good photoreal 727 panel out there - I had mine from avsim, I think.
