LOHAN spaceplane project starting to shape up nicely

Stability

The rocket will in all probability have issues with non-uniformity of thrust. A good way to compensate for this is to rotate the rocket (as stated above). The exhaust gases of the motor could be nozzled (passive nozzling rather than active) as to induce a rotational motion. Spin on the nose could be a problem for guidance (a gravity compensation will prob be required in order to maintain an escape trajectory), and for instrumentation. The nose however could be designed to be able to spin freely from the body (some form of roll control will be required). Thereby having a directed rocket burn and more stable flight. Lift will be hard to come by up there therefore gravity comp may be very difficult. A rotating body may also be harnessed to unfold any wings/control surfaces that require storing for ascent.
