The 72 is the same acting as the SR-71. In order to fly your bird, you need controlled rudder movement. So add differential thrust.
Your problems of turning is the same that I had designing my SR-72 and X-47B(no vertical or rudder at all).
Also doing right turns should be included.
You will find the designing of SR stuff and the Warthog(EDF version) are very tough projects.
How you launch it is another problem. Too steep, watch what happens. It took me awhile to solve right hand turns. The main overall problem is handling the yaw.
