What Kind Of Radio Controlled Helicopters Are There?
By: James Leonard Hampson No doubt you have already noticed that radio controlled helicopters differ in their construction and aerodynamics to RC planes and jets. There are several different base designs and some of these are more maneuverable than others, although this comes at some cost, as these models are more difficult to fly and therefore are not suitable for beginners. Possible power sources for your radio controlled helicopters include nitro (nitro methane-methanol internal combustion), electric, petrol or gas turbine. Nitro helicopters are available in at least five sizes ranging from 15, 30, 50, 60 and 90 and these sizes are basically related to the size of the nitro engine. Flight times range from seven to fifteen minutes, and you will find the larger engines to be naturally more powerful and can therefore power larger sized rotor blades. Nitro powered models have the advantage of being highly maneuverable, quick to refill and get back up in the air, but the disadvantages of
