Hello, I was running some simulations and noticed that with the Aerotech D9 (white lightning) the velocity off the launch rod was surprisingly slow. I looked at the thrust curve, and it comes up to power really slowly! For the first 0.25 seconds, it has less thrust than an Estes A8 motor! I know that the white lighting is not a fast burn motor, but other motors using the white lightning propellant come up to thrust much faster (like the E18 reload). Does anyone have real world experience with this D9 motor? How well does the thrust curve on thrustcurve.org match reality? I wonder if such slow lift offs are the case with this motor.
