Hi guys! I finally made my first liquid fuel only SSTO. It took half of my day (I never played with FAR or deadly reentry), but at the end, it went much better than I expected when I first played 1.0. 82 km orbit, and 900 m/s delta-v left. The best ascent profile I found is very simple: press T, press Z, go up at 35 degrees, turn on the nuclears at about 19 km, and shut down the air intakes when the turbojets flame out. I tried a lot of other profiles, but this was much better than anything else. I worried about heating, but it isn't a problem, the plane doesn't have time for overheating. The clamp-o-tron and the mk2 crew cabin is 2,6 t, so I think this plane can easily take 5 t, maybe 8 t payload up to LKO, or 2-3 t to KEO. Sorry for my bad english, I'm still learning it.
