Yeah I'm running it. check out RD Racing Products (rdracingproducts.com). Roy's the inventor and the only one to sell a true Quick Turn. There's a couple imitations out there but they aren't worth a poop and some say you can make your own but by the time you figure in cost and your time to make it, well you shot the $70. Here's the skinny, do you race or bash? If your a racer, it's awesome especially on tight tracks. It unloads the front end during braking (usually into a turn) and allows you to "whip" the rear end around through the turn. It keeps the truck from plowing or pushing the front end through the turn. Almost the way a center dif in an 8th scale works, sort of. If your a basher it could go either way. You'll either like it for the powersliding you pull off or you won't cause you do lose front wheel braking and the hinders some control you'll have while airborn. IMO, if your racing, it's a gotta have. Bashing, well, I don't bash much so I couldn't say.
