She done good with the extra ten fuel tanks (good lord is it that many?) I could mess around with it a bit, but the main engines are almost overheating on launch.. i was worried so i did not push them near 100%... i tried this time and they worked fairly well that way (moar thrust). Rocket was super close to blowing up, but hey..... Go Big Or Go Home. I can hit around 2900 m/s when I get the nuclear drive pushing. As of note, I have the sound off for a good reason Here is the plucky little flying skyscraper if anyone wishes to experience the thrill of launching your own city block into space! Normal and Wobbly parts. ENJOY! If you decide to try this.... know that I believe stage 4/3 is a bit complicated. 4 fires retro-thrusters and 3 detaches the fuel tanks. Be quick so you can fire up the stage 2 rockets without blowing the while ship up
