I'll second what discgolferlee said ESC wise, if you want to run sensored pick up a Tekin motor and the $50 Brushless hobbies ESC will offset the absurd price point of the Tekin.
The Losi is a good truck. But its not a drivers truck in my book. The plastic is more akin to stiff rubber; its incredibly flexible which =! great for racing. Like the SCTE, out of the box its a great handling, good basher. But compared to a well tuned FT SC10 or the like, it just can't hold up without a large amount of aftermarket parts.
Additionally, the Durango 2WD SC truck is currently being tested in prototype form, so if you're the patient type and a great driver, it may be the truck for you. (Durango 4x4 handles absurdly well, but its pretty fragile. The 2WD will be similar).
Edit: Here's a link to the Durango: http://www.shortcourse.eu/2012/02/du...-2wd-sc-truck/
I would beg to differ that xxx-sct needs tons of aftermarket parts. Losi trucks with and without upgrades dominated our track this past winter while the sc10 drivers stood on the sidelines broken. Haha
Their is no superior truck and anything can win with good smart driving!
I do think the losi gets passed on or overlooked a lot when it comes to racing because associated sponsors like 10 million times more drivers than any other brand lol. Therefore increasing their chances to podium. Not taking anything away from their trucks or great drivers, just saying look beyond the smoke and mirrors.
Local parts support should be considered when making your decision as well. The kyosho is an awesome race truck as well. Just keep a heavy supply of axles on hand for that truck.
