Hi guys, I bought eight T200 thrusters. Yes, I found some static PWM vs Thrust output figures. While I am also interested in its dynamic properties, such as frequency response, impulse response, overshoot, rise time, settling time from step response. If possible, can someone provide its dynamic model? Thank you very much. Cheers ---

Hi Wenjie, We don’t have any dynamic models of the thrusters unfortunately. I can tell you from my own observations that, with the Basic ESC, they have a rise time of about 0.1-0.2 seconds, overshoot of about 5%, and very fast settling time. I believe the ESC+motor could be relatively well modeled as a moderately damped second order system. I’m sorry I don’t have more information! -Rusty ---

Thanks for the information. Should be enough. Wenjie
