Hi all, I've got a mockup of a minimum diameter (29mm inner) rocket flying a G75. Using a streamer for recovery, OpenRocket predicts a ground hit of 36 m/s (way too fast). I'm aware from the documentation that OpenRocket treats descending rockets as essentially having no drag coefficient except for that of the recovery device. Based on this, I'm just wondering if from anyone's experience they can tell me if this number is somewhat accurate. If it is, I may have to opt for dual-deploy (not ideal) or delaying the opening of a chute somehow. I've attached the ork file.
