I'm building the Sunward Star Watcher right now, and in fact I'm pretty much done but for the painting; but I've run into an "issue" with it. I've used the alternate "X-Wing" layout for the fins, and the instructions say that nose weight may be needed... but not how much.

I don't have RockSim, but looking online it appears nobody has yet done a RockSim file for this rocket anyway (not even on EMRR), leading me to wonder if there is some reason for this. Does anyone know how much nose weight this beasty needs?
