enough to lift the R500 off the sled. Reverse process on

conventional ramp. Add enough batteries to
make the sled negatively buoyant when the R500 lifts off the

><div>Alan,</div><div>The fellow that helps me test and dive my subs
is a huge fan of tracks on a sub. We debate this for hrs after a
big struggle at a lake trying to launch.
This idea would be the ultimate system. The problem is, if it
were electric, the power consumption would be huge and put a big drain
on your batteries. I figured the only way to do it would be with a
gas motor hyd power pack. Hook up the quick connectors to launch,
then disconnect. The next problem is, tracks, even rubber, are
very heavy. The setup could weigh 1,000 lb easily if it is carrying a
sub. Then there is the cost, think big!
:-) It would be the ultimate
though!</div><div>Hank</div></div></div></div><br>_______________________________________________<br>Personal_Submersibles
