Fuel 97% Dry Mass 3% to first approximation. Various tricks, picking the right orbit, and cutting margins dangerously close can get you down to 95% maybe. > Anyone here an advocate for using H2O2 on a SSTO > craft? There are a few here.

What is the general trajectory? I have found low G's to produce much better results.
