What are the fundamentals of operating it?
-Well it's electric so you won't have much maintence at all. I don't know much about electric cars. Can't really help you out on this question much.
Is there regular maintenance that's required/recommended?
-With electric. Not much maintence at all. Just clean it off (don't use water on electrical parts) with a toothbrush or something and replace broken parts.
What is "ST Trim" and "TH Trim"?
-ST trim is steering trim. It lets you align the wheels so they're nuetral position is facing straight. TH trim is your throttle trim. Umm you have electric so I don't really know if you need that feature that much. But if you turn your TH trim up the car should have a higher idle. In the electrics if you turn it up the car will start to turn the wheels and the car will start to take off. Just turn your car on along with the radio and turn those knobs and you will see what happens. But with the TH trim hold the car and turn that one slowly so the car doesn't take off and break. lol
How long should it take for the battery to charge?
-I don't know that question. A couple hours I would say depending on the battery and charger.
How is the spare battery different from the installed battery?
-You can buy bigger batteries to hold a charge longer. So that means you can run the car longer.
How long will it run on a charge?
-On the stock battery, I don't think it will run long at all. 15-25 minutes I would estimate. Then again I don't know exact, I'm just making a educated guess.
How fast will it go?
-It should be pretty zippy. I would say top speed of 35 mph on flat surface going straight.
Why the focus on spare partsfor upgrading or tendency to break?
-Eh, I wouldn't bother upgrading anything to aluminum. Only things on the car I would upgrade or the steering servos and battery. For my cars I don't really stock up on spare parts because you never know what will break. It's always different. Like on my buggy I just had a little plastic piece break. I would have never known it would break but it did.
Does it have a warranty? If yes, what is it, and where do I get it serviced?
-It should have a warrenty. Visit www.nitrorcx.com
There are REV and NOR switches for TH and ST. What do these do?
-I would guess that's just for the steering trim while the cars in reverse. And the NOR means normal I would guess.
What are the basic troubleshooting tips?
-Well, I will say as you do rc more you become better at it. I have been doing it for some months now and have learned something every time I go out and drive. Lets just say if your car starts smoking turn it off imediatly and don't use any power on it. If you need any troubleshooting just come on here and post a question.
