I was wondering about</div><div>this & can't see any evidence to the contrary. All these brushless motor controllers</div><div>have large capacitors that could be susceptible to pressure in a compensated</div><div>motor if you went too deep.</div><div>It would be interesting to pressure test a similar capacitor to see where they fail.</div><div>The motor is an in-runner that has the coils on the outside & permanent magnet</div><div>part rotating. These have less torque than the out-runner motor, so I am dubious</div><div>of their performance statistics. <br>Still the housings are hard to make & they look like they have done a good job.</div><div>Would love to pull one apart.</div><div>Alan<br>Sent from my iPad</div><div><br>On 4/10/2016, at 5:23 am, James Frankland via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br><br></div><blockquote type="cite"><div><div dir="ltr"><div>looks a good find Hank.
