Here is my contribution to the thread : 7 kerbals SSTO, 43.537kg (wet mass), 169 parts and is able to reach an orbit of ~120 000 km. It's the latest model of a long list of crashed and failed tests (actually it's more than the fifteenth model but I lost the count). It already has four successful flight to the KSS One station. Don't pay attention to the fuel value on the first picture. For this flight I tried a longer ascent profile but in the end it didn't has any advantage over the ascent profile I usually use. Usually I end up with a little more fuel left in the tank. Hope you like it ! OrionArm
