Does anybody have a good link for a downloadable ork file for the Formula 75?
I have made my own and it seems to work okay. But my simulation weight is 3.36 lbs.
My actual rocket is 4.0 lbs EXACTLY.
Not sure where I'm missing the last .64 lbs at?
Maybe the nosecone? This kit has a metal tip and the rest is fg. So maybe I'm off by a few lbs on the nosecone?
Suggestions/download link or should I just remake it from scratch?
Thanks!

Why not just override the weight on the OR file? Then make sure the CG is accurate (by manually balancing the rocket) when empty. No sense trying to chase it down, unless you're going to disassemble the rocket and reassemble it :)

There can be some variation in tube thickness, hence mass. Did you weigh the parts or use the database?

Did you measure the epoxy you used? Did you weigh it before paint? Weigh hardware, retainers, harnesses, and chutes?

I weighed them all. I just forgot to override the default numbers in OR.
