Nice build starwarsdude, 727s were the first commercial jet I worked on outta the military. TAA? Was that a pre cursor to Qantas?
Keavdog, only passing info not picking a fight, the 3rd engine on the 727 is actually mounted between the #1 and #2 engine pods inside the fuselage, the intake we see is the beginning of what is called the "S" duct. Like you though I also like the tri motors.
