Rustys rock once you get them set up right. RPM a-arms, titanium turnbuckles, and a solid rear shock tower and you have one tough truck that flies. You replace the stock batt box with a 5 cell flat pack and mount it in front of the fuel tank and you have a speed demon that doens't have front end lift problems and won't push in the turns as bad. My rusty with the trx 2.5 will run circles around my t-maxx with an o.s. .18 tm in it unless you are running through high grass, extremely rough terrain or hill climbing. And with the rpm arms aluminum rear tower and titanium buckles all the way around, it is one tough SOB.
