I am using two T100 thrusters in a surface water vehicle. It appears that the performance of the thruster is shifted from the pwm signal being sent to the ESC. A signal of around 1250ms (instead of the normal 1500ms) is what it takes to result in zero thrust, with 1900ms still resulting in max thrust. Even further, any signal below 1250ms still results in zero thrust, not a reverse thrust like I need. I could use trim and scaling to correct the 1250ms being the new zero thrust point, but I still have no reverse thrust capabilities. I have verified the pwm signal coming from the controller is being sent correctly, but the issues may be with the ESC (a non-Blue Robotics model I already had)?
