MBB Saenger II

Named after the Austrian aerospace engineer, Eugen Saenger, MBB'S (Messerschmitt-Bolkow-Blohm) Saenger II was a two-stage-to-orbit (TSTO) horizontal takeoff spaceplane intended for use as a launch system to low Earth orbit. Development began in the 1960s with the Saenger I at the German aerospace firm MBB. The original concept vehicle was a two stage sled-launched rocket-powered aircraft intended for the same purpose. The carrier vehicle configuration consisted of a high-wing delta-wing with downwards angled wing-tips with the orbital vehicle taking an opposite configuration, low-wing upwards angled wing-tips. The the Saenger I concept would later converge into the airbreathing Saenger II concept shown in this build.

The two-stage launch system is capable of about 50 tons to low orbit in 1:5 scale system. Payload can be placed inside Horus' bay (the orbital vehicle).

Make sure part lift forces are enabled, you likely will not reach orbit without it. To stage, wait until about Mach 3.5 and activate AG 2. Make sure throttle is at 100% as you stage. Press the "]" bracket key to quickly switch to Horus and pitch up. Double tap AG 8 to retract landing gear.
