They are not available as NAR has not released the cert letters. That is why they are not on Thrustcurve- well one of the three are. The other two letters have not been released.
As I stated, I am an old fart, I use Open Rocket. I see the Sim Files for Rock Sim & RASP, but I do not know how to, or even if you can import these files to Open Rocket. Any help will be appreciated.
