Greetings all,
I'm new here, so please go easy... I've been tinkering with Rocksim for a Micromaxx design I'm working on but I have a couple of questions that only experience can answer and I'm coming up short. First up - does anyone have much of a feel for how well Rocksim's stability predictions work for Micromaxx sized models? (While I would expect it to be excellent, I'm sure I also read somplace about leaving more margin on really small designs...)
My next question pertains to one of the setup parameters for Rocksim, but I suppose it applies equally to any other larger rocket design. I noticed that Rocksim defaults the "Minimum velocity for sable flight" to a fixed value, but I would imagine this figure to be different from model to model - Is finding this speed not generally worried about, or is there a way to work out (without taking a masters course) what the real number is? Presumably it should be achieved before leaving the guide rail? Any guidance on this (pun intended) is greatly appreciated...

BTW, if anyone's curious what I'm making, it's a 1/96 scale model of a Russian P-700 Granit cruise missile. (I've removed the wings on the flight model, but left the stab/rudders and oversized the booster fins.) This comes out about the same size as, although a hair lighter than, the Quest mini Tomahawk.
