Does the DeltaGliderII carry less fuel than the original (*without* the low fuel option checked)?

I was able to get into a 200 - 300 KM orbit with the original with a little less than 50% fuel left, but

the DG2 takes more. Is this due to the turbo, or is there just less fuel?

Also, the launch azimuth equation doesn't seem to work right for me... am I missing something?

Using the formula Launch Azimuth = arcsin (cos (desired_orbital_inclination) / cos (launch_

latitude)) with a desired inclination of 74.51 (ISS inclination) and a lattitude of 28.34N (KCS

lattitude), I get 17.66, but it's supposed to be 42 for ISS from KCS right? What am I doing wrong?
