Hi all, am finishing up my LOC 4” V2 project and I created a new .ork file in Open Rocket because the .rkt file for same from Apogee Components (.rkt converted to .ork) was not working properly. My new version works as it should finally. Unfortunately OR is calling for 13oz of nose weight for a stability of 1.07. I ran simulations for various successful Aerotech G motors. I’m also running a 38mm to 29mm aluminum motor adapter along with an aluminum retainer all by Aero Tek. All of this is accounted for in Open Rocket. I’m wondering what weight you ended up with on this rocket if you’ve built and flown the same successfully. Thanks so much! Joe
