Having a problem where mechjeb dosent seem to be calculating the TWR of jet engines correctly. I constructed a rocket weighing aprox 192000kg and stacked on 12 jet boosters (made up of a jet fuel tank, 2 turbo jets, and 10 ramscoop intakes), the jets were staged first the idea being to get my altitude up to about 30k before engaging the rocket motors. in the VAB Mechjeb tells me i have a TWR of 1.26 on the ground, should be heaps once the jets spool up. however when i go to the launch pad the stage window of mechjeb still says 1.26TWR surface but the vessel info window shows .63 TWR exactly half. noteing this i increased the number of jet boosters to give me 2.5 TWR in the VAB which came up as 1.25 TWR in the Vessel info on the launch pad. this however was still not enough to get off the ground even when the jets had spooled up completely. has anybody else had this issue?
