LST is short for Losi Super Truck I think. Losi just refers to it as LST and the current (and only) model availible new is the LST XXL. If the LST is too expensive for you, a HPI Savage is probably you next best bet unless you have to have the best handling MT which is the Revo. I should've mentioned before, all MT's have similar handling traits though whether lowered or raised up. So if handling And race track time is really that much of a concern get a Truggy. The Revo will also always look lower, while the others will have more of that classic MT look to them.
