Oversized Merlin Engine

The engine in the 2nd stage on the CRS 8 Dragon that was launched on Friday (April 8 2016)
I cant put the actual rest of the rocket since its too unstable and wouldnt move in Principia without cheating, by cheat i mean by using Thrusters that are at values OTHER than zero.
ALL thrusters you do see on though are at zero. They dont do anything but help keep a stable ignition pattern of the Mines coming out of the emiters..
