Whoa Nelly
i was reading about these Whoa Nelly turbo things, and it sounds interesting. the whoa nelly sited did not provide much info on what it was or how it works. could somene clarify for me? and can u run this on a completely stock xmod?

it is a remote fet stack. its no dif then makeing a fet stack on the board, but since theres not enough room in the xmod to make a stack the remote ones are nice.

Actually, the offboard turbo can improve on the FET stack, as it allows for larger FETs to be used. Additionally, while the current Woah Nelly, newer turbos (AtomicMods' V2 and a new WN are among these) actually intercept the power (so they wind up being much simpler to install), sending a regulated 5 volts back to the ESC. The stock FETs take the 5 volts and still work, but instead of feeding the paltry 5 to the motors, they act just as switches that tell the turbo's FETs to turn on, spitting out MUCH more voltage. A nice side effect of dropping the ESC voltage down to 5V is that the steering servo doesn't jitter so much.

I have a question then. If it is like a stacked FET would you be able to run motors that require satcked FETs like the Nuke??? Or would you still have to stack FETs?

The turbo boards can handle the same motors (and if they use regulated power back to the board, even bigger ones), as they are using even more powerful FETs than the combined smaller stock-sized FETs (although you usually stack a higher grade of FETs of the same size). The reason being is that a FET stack allows the motors to handle more power, but you are still sending higher voltages to the board. Ditto for a turbo board that solders to the FETs. A regulated board intercepts the power before it ever gets to the board and ensures only 5V ever go to the board, with any extra voltage going to the motors only. Because of that, a turbo can handle ungodly voltages while still giving you very very smooth steering, since the steering servo is onlhy being powered by 5V.

you can also find alot of information from ph2t on www.mini-zracer.com including his plasmatonic motor tutorial

Not only do turboes move the fets elsewhere, they also kick it up a notch because they allow for use of better, more efficent fets on the board.
