If you search either here or at avsim, you will be able to find Erick's previous 727 model (search for 727-200 and FFX) which is also very good as a visual model. The Northwest livery is good if you can find it.
I've found the Mike Stone flight dynamics to be pretty good for this plane and I have no problem getting to cruise height. Remember that the 727 is tail heavy because of those engines and that you have to decrease your FPM as you climb to allow the airspeed to increase. If you climb too steeply the plane will stall - which is pretty much right for the actual 727!
Hope this helps.
