Boeing X-37C (With an Atlas V rocket)

This is a replica of a scaled-up version of a reusable unnmaned spacecraft called X-37B OTV. It uses an Atlas V rocket with two solid rocket boosters to take get to its orbit which can be changed then. X-37C can take to orbit and return home some cargo.

How to take off?
1. Press enter to turn on the nav sphere, throttle up to 100% and climb straight up until reaching 1500 meters
2. Then make a 75 degrees pitch. It will spin a bit, that’s ok. Then climb to 15000 meters.
3. Then make a 45 degrees pitch. Now the solid rocket boosters stop, so you can separate them.
4. Climb to 70000 meters with 40-45 degrees pitch, then set it to 30-35.
5. After the end of fuel of the first stage, separate it, start the new one and set your orbit program :)

When you reach your orbit, open your cargo bay (AG1) and extend solar panel (AG2). The spacecraft is equipped with a docking port and a spy satellite. To extend a docking port, press AG6. Then you can undock, change the command pod to the satellite, extend its solar batteries (AG7) and enjoy.
You are also equipped with RCS (AG10).

When making a re-entry, I recommend you to set a 45 degrees pitch until your craft flies straight ahead. Than you can start diving to 15000 meters, where you can turn off nav sphere control and gyroscope (AG3) and set active your control surfaces (AG5). You can help yourself a bit with airbrake (slider 1). The landing gear is AG8.

Activation groups (for a quick look):
AG 1 – cargo bay
AG 2 – solar panel
AG 3 – gyroscope (already started by default)
AG 5 – control surfaces
AG 6 – extend docking port
AG 7 – satellite solar panels
AG 8 - landing gear
AG 10 - RCS
Enjoy your spaceflight!
