KerbalX

Rocket SSTO for career or science mode.

• Upgraded version of Early Owl SSTO. Designed for reaching all the Kerbin biomes.
• Higher tech science experiments. Collect all the atmospheric science.
• Higher tech, heat resistant parts for easier reentry.
• Mostly tech 4 on standard tech tree, plus atmospheric and seismic science experiments. Tier 3 & 4 on the Tetrix tech tree. Remove science instruments to fit your tech level.

Details

• Type: SPH
• Class: spaceplane
• Part Count: 90
• Pure Stock
• KSP: 1.12.5

Accent

• Start jet engines and throttle to 100%.
• Stage to start reliant on runway to really move.
• Liftoff at 135 m/s.
• Climb at 35 degrees.
• Stage to start terrier engines at 8km (8,000m MSL).
• After 20km slowly level and stay above 15 deg.
• Aim for 74km apoapsis.
• Shutdown jet and reliant engines (hot keys 1 and 2)
• Circularize at apoapsis with terriers.

Returning

• Target 42 km about ½ way around the planet.
• After deorbit burn shutdown terrier engines (hot key 3).
• Reenter with 10 to 20 deg nose up.
• Coast during reentry up to ½ the way around the planet.
• Start jet engines (hot key 1) to fly last leg if needed. Land in the wilderness to collect science if desired.
• Stall speed is under 60m/s, (assuming rocket fuel tanks are nearly empty). Try to touch down below 80 m/s.
• Will fly on jet power to reach that perfect landing area or the runway, (with main tanks 50% or less). Unlock emergency nose tank if fuel goes dry.
