O.S. Engines

An O.S. engine is like a little machine that powers things like toys and model airplanes. Inside the engine, there are parts that move really fast and create energy. This energy is then used to make the toy or airplane move. Think of it like a tiny car engine but smaller and more specialized. People like to use O.S. engines because they are very reliable and can run for a long time without breaking. However, they need to be taken care of properly, just like taking care of a pet, by making sure they are cleaned and maintained regularly. So, if you want your toy or airplane to work well, you need a good O.S. engine!
