Alan,
What was the max depth that you tested your ambient sub?

Hi Tarek,
these were brushed. There are very few inexpensive brushless trolling motors
around.
One or two Chinese trolling motors I know of but generally a lot more
expensive.
There is nothing in the way of electronics inside the brushed motors.
The main thing you have got to look out for if you want to either oil or air
compensate electronics is the big cylindrical electrolytic capacitors. You
get these in motor controllers. What pressure they crush at I am not sure.
Would be a good experiment to put a bunch of various sized capacitors in a
pressure test chamber. You can pot around them with resin to strengthen
them.
I am making my own brushless thrusters from brushless sensored outrunner
motors, & oil compensating them.
