You also need a V12 in place of that twin-rotor Wankel booster...  |
I am always "  Sky Happy " Craig, especially at test flight time  .
To fix the LL problem I could add an lower LL at the bottom of the 2nd stage and use a 48" rod, should have done that anyways for the SLS design. Good catch. Also have notice with the Fixed file from Bob that the Dv's are a little higher and may need to make some design/ fin adjustments.
Thanks for the input Craig, JP.
