A big Tip for Maintaining a Nitro engine is when you feel like you're not going to use it for awhile, strip it down and give her a good clean, she'll thank you for it next time you try to run her, and after the cleaning throw some after-run oil in her to keep her smooth and lubricated.

Whenever dealing with an Electrical Motor, the most important thing is to keep an eye on your battery. Never let an RC battery run completely flat. i.e, The vehicle stops moving on it's own, and always keep some charge in the battery, even after long period of inactivity give it a charge with a good charger, preferably a balance charger so you can see how the battery is holding up, and Remember if your battery is starting to get a bit puffy, it might be time to get a new one.

If you have one, you know that they don't need much love, Just like a weed-eater or lawn mower, she'll run not matter what. However, some love is still needed. Make sure you're using the correct mixture of fuel which is normally provided by the manufaturer for the oil you'll use. There are also oil and fuel mixture charts available online, handy and ready for you. A little foresight can save you alot of trouble.
