<b>Thrust vectoring (gimbal):</b> This is an educational scheme in which the stick motion directly controls the engine gimbal, i.e. the pilot needs to do the task of the PID controller himself. To make things somewhat easier, the engines are automatically vectored through the stack's CoG, i.e. outside the atmosphere stick neutral corresponds to zero moments acting on the stack. In the atmosphere, the control input hence needs to compensate for aerodynamical forces. Launch in this scheme is fairly rough and it is not possible to reach high precision, but it is possible to fly into orbit and gain a first-hand experience of the forces acting on the stack. | <b>Thrust vectoring (gimbal):</b> This is an educational scheme in which the stick motion directly controls the engine gimbal, i.e. the pilot needs to do the task of the PID controller himself.

{{Key press|m}} switches between the ascent DAPs. {{Key press|Control}} + {{Key press|m}} switches from the ascent to the orbital DAP modes (do not use an orbital DAP for ascent control unless you know very well what you're doing). | |||
