It is very light and operates smoothly. The speed is perfect and about the same as my hydraulic functions on my current arm. Air compensating will be a breeze by drilling into the end cap and threading in a fitting. A second vent hole will have to be drilled in the casing to allow air to move freely between the two halves of the actuator body. I spent about 250 Canadian for one actuator, so a four function arm would be 1,000 dollars. I will put it all together and see how it works but I am confident it will be a big improvement on a hydraulic set up both in cost and weight, not to mention complexity. By adding air compensation, it gives me an excuse to air compensate my vertical thrusters. I will mount a dedicated air tank for this set up.</div><div>Hank</div></div></div></blockquote><blockquote type="cite"><div><span>_______________________________________________</span><br><span>Personal_Submersibles mailing list</span><br><span><a href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a></span><br><span><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a></span><br></div></blockquote></body></html>
