I too run the trackstar turbo 120amp in 2 of my basher car, and they work flawlessly. Very smooth and powerfull. Seems like no matter what I gear too, they always run cool...or maybe I'm not trying hard enough to cook them lolol. my main race cars run Tekin's, but I've got no problem running the Turnigys or HW/HK's in their place.

And just to be clear, there is a specific programming box that has to be used with the "turbo" Turnigy ESC's....they don't work with the widely universal Turnigy/HW programming LCD box posted above.

If you want to program the 80a/120a Turnigy Trackstar Turbo ESC's you need this box here...same with ESC firmware updates...must have IMO.
