Okay. I designed a large tube finned rocket in RockSim. I put the values in Thrust Curve and got what it considers appropriate engines. Thrust Curve gives an altitude of 730 ft with a GT-80 and RockSim, using a GT-80 as the motor, gives an altitude of 1800 ft. Any thoughts about what the two approximations have to say?
