I just started using Rocksim. I looked at the model weight when trying to find a fix.
I have used a lot of FEM programs, so I know that it is often the little most obsure thing that gets you. I started with the Cherokee Triple D. I always liked the Cherokee, and Delta two stage D models. I had built a Nike like two stage D model 10 years ago. Used a scaled booster with a ported stageing design that had a booster about 6 inches long. It flew well.
I have also used a potrted booster with a two stage mean machine going from D booster to E Mean Machine second stage.
Thanks for the help.
