8. Two engine RC models

This is another group of airplane models. They're basically the same as all the other plane toys, except they have two engines. The engines can also be electric or glow plug. In some cases if you need more power you can install two-cylinder glow plug engine instead of two single cylinder engines. I'll give you an example. If you already have a RC model and you decide you need more power or you just want it to fly faster, it's easier to replace your current engine than to add one more. The problem would be where to put it? You would have to make some modifications to the fuselage, which in consequence can mess up the plane model if you don't have some experience. Installing two-cylinder engine also requires some modifications, due to weight increase in the nose of the plane models. The point is, if you are not experienced hobbyist, don't do it. If you want two engine RC model, buy it as RTF (ready to fly) and enjoy!!
