I'm quite surprised you started off with an old nitro R/C for a first...that's quite a learning curve. To read up on your Nitro Sport, check the Official Traxxas forums or just ask us what you want to learn about in particular.

HeY!!!


One of most important things is to constantly stay on top of the motors settings because they will constantly change all the time.... mainly the low and high end and all that should be on the traxxas website... just go to your lhs and they should help ya tune it out and explain everything in detail.... if not we could prolly tell ya what to do, or try to help. good luck and have fun!!

Learning how to "monitor and change" the settings is basically the learning curve. Nitro takes a good year to get the hang of tuning as far as I'm concerned. First thing you should do is get yourself a temp gun. Tower sells one by duratrax for about 26 bux. You want to run it around 220 degrees generally. The cooler you run it the longer the motor lasts. You keep it cool by adjusting the carb mixture settings. The more rich (more gas going into motor) you run it the cooler it stays.

Now you've also got to balance the low speed needle and the high speed needle together to get the acceleration and top speed you want while maintaining a decent temp. Also thrown in the mix is the idle speed, brake adjustments, and clutch tuning. It's a ton of stuff to learn how to adjust, and how to troubleshoot. If your settings get off to much, the thing won't even start. Or the glow plug could fail and you may attribute not starting to bad settings or worn motor. I could go on and on. But I'll give you a couple good tips.

Always tune the high speed needle first. It feeds the low speed needle.
Then tune the low speed needle for the take-off you desire.
Then tune the idle so that it's not to high, yet not so low it stalls.
Brakes, well that's a personal preferance, just set enough to hold it still at idle to begin with. And set it with the linkage, not the radio trim.
* To richen turn counter clockwise, to lean turn clockwise.

Once you get good enough after a long time, you won't really need the temp gun. You'll be able to set it by feel, sound, and performance. Good luck to ya.

Welcome to nitro! You'll love it.

Brief overview with some startup/shutdown vitals.

Do yourself a favor, right now, don't hesitate, invest $25 in an Ofna Micro or other failsafe and search forums for throttle return spring.

If you lose radio signal, often the engine will go to full throttle and what happens next is anyone's guess. Usually it's an unfortunate meeting with an immovable object or a blown engine. A failsafe closes the throttle and applies full brake until you can figure out what went wrong.
