Over the past couple of decades radio control equipment has become more reliable, cheaper and smaller. The latter means that large models are no longer required to cary the bulky items that made up early radio gear. This has a knock-on-effect in that smaller models can be built more quickly at a lower cost - two very attractive ideas!

It might be thought that a smaller model might not perform as well as a large one but after designing and building twenty such small models the author has not found this to be a problem. In fact, the speed and economy at which they can be built has proven to be a great advantage in that new ideas can be tried out before using in larger models.
