Scientific, government and military organizations are also
utilizing RC aircraft for experiments, gathering weather readings, aerodynamic
modeling and testing, and even use them as drones or spy planes.
There are many types of radio-controlled airplanes. For beginning hobbyists,
there are park flyers, and trainers. For more advanced pilots there are glow
plug engine, electric powered and sailplane aircraft. For expert flyers, jets,
pylon racers, helicopters, and other high end competition aircraft provide
adequate challenge.
A distinction is typically made between hobby grade and toy grade model
aircraft. Toy aircraft are exclusively electric, have less power, and require
little skill to fly. As a result, they are much cheaper (less than $75 or so).
Hobby grade aircraft come in all varieties, from small electrics only
distinguishable from toys by the brand, to multi-thousand dollar craft with
hundreds of cubic centimeters "under the hood".
Park flyers, as the name implies, are small, easy to fly electric aircraft. They
are designed with the average flyer in mind, requiring an area no bigger than a
park to fly. They are low budget and easy to fly. Trainers are similar to park
flyers in that they are on the docile side and are comparatively inexpensive,
however, they are bigger and are usually glow (gas) engine powered.
Gliders are planes that do not usually have any form of propulsion. As most
gliders are non-powered, flight must be sustained through exploitation of the
natural lift produced from thermals and wind hitting a slope, Jets tend to be
very expensive and commonly use a turbine or ducted fan to power them. These
aircraft can often reach speeds in excess of 200 mph. They require incredibly
quick reflexes and very expensive equipment, so are usually reserved for the
expert. |
