Something has happened with updates since 1.2.2, as a result the Pegasus launcher now (1.3.1) is too much unstable and is unflyable. I will try to figure how to correct it.

Precisely a week ago I discovered the excellent Stargazer L-1011 + Pegasus made by KerbalAstronautics and it gives me back the envy to restart my old own project of Pegasus launcher. Started under 1.0.2 the main problem at this time was the lack of a good and powerful turbojet engine for the carrier. Problems, problems and still more problems, I just deleted the carrier file and kept the Pegasus rocket for better days. 1.0.5 arrived and still I was not thinking about it, then while discovering the craft by K.A. I suddenly remembered that yes, there is a Pegasus waiting in the SPH, and now the Goliath I never used before is available too!

Named Chrysaor, the brother of Pegasus and son of Medusa, the launcher is coming with its carrier, Kalliroe (an Oceanid). The last one is a kind of replica of Orbital’s Lockheed L-1011-1 TriStar nicknamed Stargazer used to carry and drop Pegasus on most of its mission.

About ten different test flights were made to try the craft and realize some small adjustments and now it seems to be good enough to be share.

The launch sequence is really basic, start the three Goliath turbofans, rotate around 90-100 m/s, start the climb while getting about 170-200 m/s, keep-on climbing and once around 5000-8000 m try to keep the X angle flat and stable as possible, drop Chrysaor and you get as much time as possible to compensate any stability problems if you want. Flare just a bit and once ready light the first stage. 3 Thumper and 3 Sepatron SRB are imitating Pegasus 1st stage. Keep on accelerating and climbing. The rest is dependant of your wishes.

More personally the whole craft is the first in a long time that I flew totally in manual. The system appears to be extremely stable, the carrier as the launcher, and can be controled without any autopilot-like programs during the whole launch sequence.

The craft file is coming with a simple relay satellite of about 1.5 tons, only built to proove the capacities of the whole system.

A stock aircraft called Chrysaor-Kalliroe (Pegasus-Stargazer). Built with 93 of the finest parts, its root part is probeCoreOcto2.

Built in the SPH in KSP version 1.2.2.

As usual the flight album is available

Chrysaor made its job perfectly
