This craft does not use TesserWreck’s Stock Fuel Switch. IFS fuel tanks are once again mis-identified by KerbalX.

Positron powered heavy lifter space plane. Can deliver 14 Kerbals and 100t of cargo to anywhere in the Kerbin system. Use HTP as fuel.

Fly-by-wire (e.g. Atmosphere Autopilot) and ILS mod (NavUtilities) are highly recommended.

Full load take-off instruction: set engine to atmospheric mode and max thrust. Keep pitch up at 20-30 degrees during initial climb to 4k and gently transits to level flight at 18k altitude without losing speed. Keep level flight until reaching mach 4.5 and start climbing again at around 10-20 degrees pitch. Switch to HTP fuel when thrust drops below 1000N. Keep at least 30 seconds to APO during the climb to 70k.

Empty load landing instructions: Final landing speed is lower than 40 m/s. Therefore, it should be no challenge at all.

A mod aircraft called AM-1 Heavy Lifter. Built with 62 of the finest parts, its root part is j.cockpitv2.

Built in the SPH in KSP version 1.12.5.
