This is the first plane in the CS2 series. The subseries 13x. The naming of this plane:
RCJ (The "Commercial" or "Civilian" aircraft class)
CS2 (Classic Series 2)
131 (The subseries of airplane, this is the first model so it gets a "1")

Engines:
1x J15 (Mounted in front of vertical stablizer)
2x J50 (Mounted on sides of aircraft)

Landing gear:
1x Large retractable gear (Turnable w/ Yaw)
2x Wing landing gear

This is a short-medium range plane based off of the Boeing 727-100. Not a replica as it uses turbojet engines and has a lot less rows. I have thoroughly tested the plane and it is stable during flight (Use TRIM if you don't.). Takes off on the runway at Yeager airport properly, and lands and brakes on the runway at Yeager airport without going off the sides. A problem that many of my planes have. Enjoy and please comment!
