Portmonde

Actually my TWR is about 0.06. No need to do the maths though, i have a mod for that. This is right, but time isn't my problem, fuel is. Also, i can't really 4x since my ship contains a lot of docking port, that wreck it above 1x. Thanks for the explainations guys!

Hi guys. I've recentrly crafted, in the hangar and in orbit around Kerbin, my biggest ship. It was intended to beat the Jool-5 challenge. I got him out of Kerbin's orbit with a mainsail, and I had already noticed it was longer than usual. Then around Kerbol's orbit, I did a maneuver node, the delta-v needed was around 350m/s, and my engine was the nuclear one, that thrusts at 60kN. Only, the burn time was over 15 minutes, and it wasn't a display bug from KSP. Is this normal? I thought in space the weight of a ship didn't matter. I precise I have no particular mod. I've already put about 200h into the game and this problem has been so frustrating I signed up here. Anyways, I really need your help, kerbonauts!
