Correct, & I believe some refer to their new winds as a Thin, Short Stack, & at the moment, the companies I can recall that are using them, are TSR(The One), Fantom(their FR-1v2), Team Powers(Actinium v2) & Motiv(MC2, or M-Code 2). But before you bolt in the hot motor of the month, it's best to focus more at first on car setup & driving. And for that, I think it's a good idea to have something cheap but decent to practice with & have as a backup, like the Trackstar ROAR-legal V2's, they're a surprisingly stout motor, at a bargain price(you can get one from around $46 or so). Use the budget motor at first until you feel that you're driving well enough that the motor is actually holding you back, then you bolt in the big gun & unleash the beast....
