RC gas cars

Plenty of hobbyists think they treat their rc gas cars well, but overlook an important element: the maintenance and upkeep required after you are done for the day. It's good to do the usual checks and adjustments before you race, but once you are done it's important to get in the habit of doing a few basic things as well.

One key element of maintenance for rc gas cars is draining the fuel after you are done for the day. The best procedure is to run the tank dry, to ensure there is no fuel left in the engine. If you have to drain the fuel, there may still be some left. The reason that fuel needs to be drained is because it attracts moisture, which encourages rust and corrosion. (Gasoline is the opposite: it repels moisture, which is why it's fine to leave in the tank for full sized cars.) You will also want to disconnect the fuel tubing from the carburetor.

After making sure the fuel tank and lines are dry, rc gas cars will benefit from some quick attention to the glow plug and air cleaner and an application of after-run oil. After that, a quick rubdown of the entire car with denatured alcohol will finish the job.
