After-run maintenence

After you finish running, after each day, you have to do all of the following to help keep your nitro car running the best it can:

  1. Attempt to run the engine until all the extra fuel is burned up. Nitro has alcohol in it, which attracts water which will rust the engine. Make sure the fuel tank is empty. You can use the fuel bottle to remove any excess.
  2. Remove the glow plug and insert 2-3 drops of after run oil, and pull the cord to turn over the engine to spread the oil. You can also remove the air filter and insert 2 drops into the carb as well.
  3. Put the piston in BDC (bottom dead center) position. The sleeve is tapered, so you have to put the piston at the bottom position to let it cool properly. To do this, remove the glow plug, and put a soft object such as a Q-tip into the opening. Pull on the pull cord and stop when the piston is as low as it will go. Once it is there, make a mark on the flywheel with a marker so you will know where to put it next time.
  4. Take off the wheels, spoiler if there is one, and body and wash them in the sink with water. The dirt will easily come off. Set them aside to dry. Also you want to wash out the air filters, with water and soap, and rinse the fuel bottle out.
  5. Now you have to clean the actual car. Don't use water. It will break the electrics. I like to use an air compressor because it easily blasts everything away and leaves the car clean. If you don't have one, you need to use a paper  towel and a toothbrush. You can also use WD-40 as it is safe for electronics.
  6. Remember: transmitter always goes on first, and off last.

And that's it! Remember to do this after every day of running.


  1. Just like a real car RC cars and trucks require regular maintenance. After running your RC for a while you have to perform after-run maintenance. All radio controlled vehicles electric and nitro need after run maintenance but some of the steps here apply only to nitro engines.

  2. Wouldn't it be nice if an RC vehicle air filter could be long lasting, perform at the highest levels in terms of stopping and holding dirt while mitigating restriction and maximizing power and NEVER require oiling?

    Imagine running the same filter throughout the weekend, including during the nastiest conditions and simply blowing it clean with compressed air from inside-out as necessary.

    Well, that level of engineering now exists! R2C Performance is designing its Pro Series Race Filters for RC Buggy's and Trucks. Testing is underway and the results and feedback are outstanding.

    Cleaner engines, more run time and fuel efficiency and simple maintenance!

    R2C race filters for RC applications will be available soon.

  3. Very useful information, I just wanted to add that you should make sure that the engine cooling head should be clear of dirt, you don't want any dirt dropping into your engine when you remove the glow plug.

  4. What model of car are you using in the pictures? I have the exact same one but I don't know what it is. It was a gift lol. I would really appreciate the help! Thanks!
