I’m testing the behaviour of the T-200 thruster using different propeller models in order to determine the most efficient one. I can’t obtain results because the T-200 behaviour when underwater is very weird. I send a servo.write command from 1500 to 1900. During this process I read the thruster current consumption. The current consumption and the thrust of the Thruster increases until it reaches 1600. At this point the current consumption and the thrust from the T-200 remains fix although orders of over 1600 are sent.
This weird behaviour appears only when underwater, if I perform the same experiment in the air the T-200 shows a normal behaviour.
I add two videos to show the problem:
Anyone know what might be happening?
Thanks for the advance
