Question Modifying the CVEL Titan SSTO for Mars

[perludus]

I'm playing around with some Mars scenarios, and wanted to try launching the CVEL Titan SSTO from Mars, specifically wondering how much the weight of the probe (payload) could be and still get into orbit from Mars.

My first attempt (just take existing scenario, move ship to Olympus) ends up basically taking me completely out of orbit. Rather spectacular, but not exactly the orbit I wanted.

Any advice on how to modify the SCN file to get this to happen? How to get that overpowered lifter to just not be so... powerful?

As a scenario, suppose I wanted to launch a Gemini Titan II into orbit to rendezvous with Phobos. Phobos has a semi-major axis of 9,377 km and orbital inclination of 0.015. And here is the SCN file for the CVL Titan SSTO (assume I modified the MFD to "REF Mars").

END
END_SHIPS

I am (as an Orbiter n00b), just not sure what to put in there to get the autopilot to fly me to the right orbit. Forget timing my launch to rendezvous, etc. - I just want to get into the right general orbital altitude (via the Autopilot).

Don't think so.

Ok, I bit but I don't think it can be done. No matter how high you set the weight of the probe, the autopilot pitch program is calibrated for Earth and will not pitch over until an un manageable amount of verticile speed is reached.
try this:

Some think flying to LEO in a single stage requires hyper-advanced materials or propulsion. Not true! Here's a single-stage rocket, built

in 1960....
Of no practical utility, but it's a neat hack. And I needed it to test the code anyway.

You won't even reach orbit, but still no pitchover.
