The need for speed! Radio controlled model jets are considered by many RC pilots as the most exciting and exhilarating of any remote control airplane that a person can fly. These models can reach speeds of up to 100 miles per hour and the turbine models have been clocked at over 250 mph, therefore they are not for the beginner or the faint hearted, you could get seriously injured if you don't know what you are doing. So you are an experienced Rc pilot and you want to fly jets, how do you get started? The first step is to learn about the different types of RC jets that are available, and what type of engine powers them. Basically there are three main classes of model jet 1.Propjets 2.Ducted fans 3.Turbine, your choice of model will be determined by your level of skill and by how big your pocket is!! i.e. (some models can cost over £5000)
Propjets (Rear mounted-pusher) Propjets (electric)
Ducted Fan
The most recent re-launch of ducted fan technology, has come from the influx of light weight electric ARTF models entering the market, some kits even have twin ducted fan units installed at a cost of less than £70. Many big name companies in the modeling world have produced some very fine models with a fantastic performance and price to match, e.g. Ripmax F16, Multiplex Twister, Alfa Models F86, Mig 15, A4 Sky hawk, GWS F15, PN Designs Me 262 and many others. If you want a small high speed jet at a price, then electric jets would be the way to go, many already have.
Turbine A jet pilot from Scotland once described it as “when flying jet turbines, they are so fast, that you can't get a credit card between the cheeks of your backside!".
Companies such as Jet Cat, Wren, Graupner, all provide various types of easy start turbines with a good selection of spares and service backup for the jet pilot who wants to get into the air quickly. The turbine used in a model will depend on the size, weight or even scale of the jet in question, usually a model with a good thrust to weight ratio, e.g. (1:1) will fly well. When choosing a turbine, you will be asked by the supplier "how much static thrust do you need your turbine to produce?" usually in pounds, e.g. a Jet cat SE120 turbine, with produce 28lb of static thrust, a jet model weighting 28lb will have a 1:1 ratio, therefore it should fly well, however if you are uncertain, do your research before you buy. Jet models are no different to other types of RC kits, them vary in size and weight, and of course price! The number of ARTF jets available over the counter or direct from the manufacture, have increased greatly over the last few years. An influx of cheap ARFT models from China and other Asian countries have taken the market by storm, companies such as Sky Master, Fio Beo, produce a large selection of fine scale model jets in the ARTF range, some will even supply a complete model RTF, a few nights work installing your radio equipment and setting up your turbine, and your ready to go.
This article only touches the surface of the sport of RC jet flying, the best way to obtain information, is to visit local clubs, shows and ask experienced jets pilots how they started and what is a good model and engine to start with, most jet pilots are only to willing to share their knowledge with future jet jockeys, so don't be afraid to ask questions when you get the chance, remember good pilots never stop learning. |
