Remember a scooter is 400 lbs with driver. Also tracks take a lot of power to turn, especially a rubber track, without any weight. Then think of the power it would take to climb the ramps. Believe me, I wanted to try this, I was going to borrow tracks off one of my excavators. It is simply more trouble than benefit. </span></div><div style="color: rgb(0, 0, 0); font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;

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></blockquote></div><blockquote type="cite"><div><span>_______________________________________________</span><br clear="none"><span>Personal_Submersibles mailing list</span><br clear="none"><span><a href="mailto:Personal_Submersibles@psubs.org" target="_blank" rel="nofollow" shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a></span><br
