Hi all
I am designing a very purpose specific ROV where pure speed is a critical part of the functionality. I am wondering if anybody has ever used a set up where T200s were in line nose to tail and what their experience taught them. In particular, I really would like to know to what extent the overall efficiency is impacted by the proximity of the second thruster because of the disturbed water flow. Any input welcome!
thanks
John
Hi @johng,
I haven’t done actual testing with a setup like you’ve described but I’d recommend using counter rotation, as discussed here 
Much appreciated Eliot. Makes sense.
