First of all I would like to say, I understand that the Center of Gravity (CoG) changes as the Launch Vehicle’s fuel level decreases. I have tried to launched a few Satellites when the first stage drops off & the second stage ignites the Launch Vehicle begin to cartwheel, I know it’s because that my Launch Vehicle is “top heavy” & that throws off the CoG.
What I don’t understand is how to fix the problem could you please explain it in plain English.
Thanks,
