#SSTO #Cargo

- Type: SPH
- Class: spaceplane
- Part Count: 126
- Pure Stock

- Fuel Cost: 7244


Proven to lift up to 34 tons to 80-85 km orbit with ~350 m/s of Delta-V to spare.

Cut down version of Xylan 4, with 3x4 engines instead of 4x4 engines, shortened fuel tanks and wings. Since most cargo lacks the mass to warrant the Xylan 4 high lift capacity but rather needs large cargo bays, the Xylan 3 is more practical at lifting cargo for an overall cheaper price in that it cost 41% less in fuel to operate than the Xylan 4.

To Orbit Procedure:
1. Run off the runway at fullpower.
2. Pitch up to 20 degrees, maintain that pitch.
3. Switch engine mode {1} and close intakes {2} once speed begins to decrease above 22-23 km.
4. Shut off all engines once predicted apogee exceeds 80 km.
5. Coast in pro-grade orientation to minimize drag.
6. Circularize orbit at apogee, switch to just inner engines {3} for orbital manuvering

From Orbit to Spaceport Procedure:
1. Reduce Apogee from 80 km to 20 km with spaceport at Antipole.
2. Come into atmosphere with a 20 degree pitch up.
- You can slow down faster by pitching higher up, or flipping upside-down and pitching down.
3. If needed you can use the inner engines on jet mode to cruise to spaceport.
4. Land at spaceport below 100 m/s, put brakes on and pitch down.
- If you land above 100 m/s or long on the runway, use parachute to slow down faster.

A mod aircraft called Xylan 3. Built with 126 of the finest parts, its root part is probeStackSmall.

Built in the SPH in KSP version 1.3.0.
