Air Filter Preparation on A Nitro RC Car
Here are some handy tips on how to prepare and air filter for a nitro based RC car from member Matt Parker...
"Having an effective and clean air filter on a nitro car is essential for stopping dust, dirt, and other bits of track debris from entering the Carburettor and effectively damaging the engine. Here is a quick guide on how I clean my air filters. I clean my filters after every two meetings at Adur or if I am running on a dusty track such as Kent then I will clean the filter after every meeting. In this guide I have taken the engine out of the car but this can easily be done with the engine in situ."
- Cut the cable tie and remove the air filter from the car and straight away cover the filter inlet or use a carb plug to stop any dirt or dust in the carburettor while the filter is removed.
- Put some gloves on and work outside! I clean the old oil out of my foam filter element with Petrol and give the foam element a good going over with my fingers to work all of the debris out of it.
- Remove the filter and allow it to dry thoroughly ideally overnight.
- Place the cleaned and dried element in a small polythene bag and squirt a generous amount of air filter oil in. Seal the bag shut and really work the new oil into the element. Doing this avoids you getting blue fingers and looking like a Smurf.
- Refit the element onto the filter and remove the tissue/plug from the carburettor and refit the element to the filter.
- Using a new cable tie refit the assembled filter tube and element to the carburettor. A strong seal here is very important as if you get this wrong then there is a risk of debris entering the engine and ruining the engine. My test for a secure fit is to be able to lift the car up by the air filter without the air filter coming off the car.
Go out on track and have fun!
