Do you want hardware or computer spec? Hardware is - Right click my computer, scroll to properties and click. then click the hardware tab and within that click 'device manager'. Computer spec is basically the same except you'll see it when you first click properties.
I think the pads can be expensive. But if you purchase pads if the 'normal' backings from heatsink they are all pretty much the same price as other pads. Its when you add on different parts such as the cnc backings that they become expensive.
Ive heard zoo's are supposed to be really very good for the money. Be quick though, they arent being made anymore. I think a couple places still have some stock left.
What car/truck have you got? What fuel are you using? What nitro content has it got? Try adjusting the needles (high speed and low speed if it has a low speed one). Only slightly each time though, about a quarter turn. Or just go back to the factory settings which are usually a bit rich but allows it to start easily. If you still cant get it started you will probably have to take it to your local hobby store, i dont think you would want to be taking apart your piston etc if you are a 'total noob'
