Product Advantages

Large Thrust to weight ratio, can quickly rise to kerbin low orbit.
No extra appearance decoration, low aerodynamic drag. Enter kerbin low orbit to save 50% fuel.
There are a variety of devices to support.
More than one hundred test data allows you to quickly learn about the space plane.
Docking port placed on the nose, easy to dock.

Launch

step:
1. Start the KS-25 and CR-7 engines and take off when the SS16 speed = 120m/s.
2. Maintain pitch 10 degrees.
3. When the SS16 speed = 400m/s, turn off the KS-25 and increase the pitch to 15 degrees.
4. At an altitude of 8000m, reduce the pitch to 10 degrees, or set the direction to prograde.
5. At an altitude of 25000m, 0m/s, turn off the KS-25 and increase the pitch to 15 degrees.
4. At an altitude of 8000m, reduce the pitch to 10 degrees, or set the direction to prograde.
5. At 25000m above sea level, convert CR-7 to closed cycle mode and start ks-25.
6. When the speed is = 1800m/s, turn off the CR-7 engine and set the direction to prograde.
7. Continue to accelerate to low orbit.

Check spacecraft weight balance and Flow Priority before takeoff

Reentry & Landing

Reentry data

Data sheet: https://drive.google.com/file/d/1L1k4rfAc31U4X5pS7R_oUznjMk9AlopG/view
The longitude here is for reference only.
If the space plane is heavy, increase the longitude.
If the space plane is lighter, reduce the longitude.

At the reference longitude, start KS-25 Burn PE to 40km.
Check the weight balance of the space plane before re-entry into the atmosphere.
Maintain pitch 40 degrees and check the weight balance of the space plane during air braking.
When the ground speed is reduced to 1100m/s, the aircraft to level flight
Rely on experience to maintain or reduce speed, beware of aircraft overload.
When the distance from the runway is only a few kilometers, the speed is controlled between 200m/s and 100m/s.
The wheel turns to the ground and opens the parachute.
