KerbalX

This OPT space plane was designed for Umbra Space Industries life support, and colony focused games in mind. set up for multi purpose payload delivery with life support and habitat time. Works well as a fuel and supply tanker in late career mode. The current payload includes a 3 Kerbal Lander, supply containers, and some life support systems. Put what ever heavy stuff you need to lift in the payload bay.

Launch with all engines firing and climb to 45 degrees pitch angle.
start to level out gradually and get the speed up to about 500 m/s to ramp up the high altitude turbo ramjets. Once the ramjets kick into full thrust usually around 500 m/s around 10000 meters altitude. shut down the 4 S.C.O.O.P. rocket engines with action group and use as needed to keep desired prograde pitch angle. The Dark drives will gain thrust with altitude. Once you get an efficient accent profile figured you should have plenty of fuel left to explore the Kerbin system and accomplish multiple contracts or goals around Mun and Minmus. If you Tank up more fuel into LKO with another Falcor you could do many other things.

Switch off Vernor attitude control engines with action group until needed for reentry. Some fuel balancing may be required before reentry depending on remaining loads. Transfer all fuel out of the pylons, and wings into middle tanks once in space to minimize deviations between center of thrust and mass. experiment with loading in the SPH to get the desired center of mass. 40 above prograde works to begin reentry. Use the Scram jets as needed to adjust decent back to the runway. Its easy to land despite the large size. Allow enough runway for breaking.

If you are making a reentry with a re docked lander I recommend you fuse the Construction docking ports for stability.
