I really like this idea, how do I make it with with Ven's stock revamp?

Well, to be fair I still got it into orbit even with all those issues. So, it works, but is a real handful. Doubling the mass of the SRBs would go a long to way to calming it down and making the ascent far closer to reality.

Questions/Issues about the RO version: Orbiter.cfg is missing a bracket in the RCS section. Fixing that got me RCS, but the rear thrusters appear to be firing perpendicular to their actual orientation. The makes attitude control problematic to say the least, particularly during OMS burns. During initial ascent, she really doesn't want to pitch over, and max-q gets way higher than the real thing, even with half-throttle (lower than the actual engines could throttle) set at launch. I saw max-q of 50,000 pa. Maybe too much thrust in the SRBs? After SRB seperation TWR is right about 1.0 so that seems right. Speaking of SRB Sep, those things go nuts at separation. usually banging into the ET, with a lot of rotation applied to them. I looks like the nosecone rockets are way to powerful. I know the real things separate while still producing a small amount of thrust so I experimented with that with mixed results, even right before they burn out with less than 5% rated thrust they still try to outrun the orbiter. *edit* I've been going through the numbers and the SRBs are overpowered and way too light. The SRBs weigh half as much as they should and have a good 10% extra thrust. As a test a set them to half thrust in the VAB to get a 1.5T TWR and that resulted in a much more reasonable ascent, still with a crazy separation though.

This is going to be great. Once this is working reliably I'm going to have to rebuild my Minmus base with welded parts so it hopefully doesn't being the game to a crawl anymore, or at least speed it up to more of a slow walk.
