Here is an upgraded version of the X10B-2, called the X10D. It has improved stability, and two satellites which can be deployed once above the atmosphere. The vehicle can be operated as follows:
Group 1 ignites the core engine.
Group 2 ignites the boosters.
Group 3 will launch the rocket.
Group 4 drops the fairings.
Group 5 detaches the boosters.
Group 6 deploys the X10D spaceplane.
Group 7 deploys the satellites. Works best above 350000ft.
VTOL slider is used to give spin stabilisation to the rocket.
Pitch controller adjusts the pitch. Use this only shortly after liftoff before adding spin to the rocket. Less pitch = more altitude, less downrange distance. Experiment with the pitch until you find an ideal trajectory.
To slow down from hypersonic flight, pull down on the pitch and brake controls simultaneously.
Feel free to create and add your own payloads, or make improvements and other alterations to the design.
