<div dir="ltr">James,</div><div dir="ltr">I do not have this problem with the smaller motors, the brushes are at the other end of the motor, opposite the propeller end. On my DDW, I am using 4X 30 lb thrust motors. I find with the visibility we have there is no need for faster bottom travel. I would say being similar in size to your new sub, no more than 50 LB is needed. I have a video on how to modify them and it takes about 20 min per motor. </div><div dir="ltr"><br></div><div dir="ltr">I also have 50 lb motors that I actually drilled the motor body and screwed in penetrators with short leads that plug into the brushes.</div><div dir="ltr">Hank</div><div><br></div>
