Electric Rc helicopters are radio controlled helicopters that are not only favorite with children but also with adults. Thee model aircrafts are dissimilar in terms of the aerodynamics, the training required to fly them and their construction from Rc airplanes. These helicopters are ready in assorted designs each with varying levels of complexity. However, complexity of design, like in the case of collective pitch aircrafts, also means great maneuverability and aerobatic capabilities. The design, features and the operate surfaces of these small models are analogues with those of full size helicopters.
The flight controls of radio controlled helicopters consist of controls for the collective and the throttle which are commonly related together, operate for the tail rotor responsible for yawing and operate for the cyclic that is responsible for the pitch and roll movements.

Small servo motors are used to affect these controls. The engines used to power radio controlled helicopters are commonly two stroke motors that use methanol, but the newer versions have brushless motors that need a lithium polymer battery. You can also find engines powered by gasoline or jet turbine fuel in some models.
Two of the most favorite versions of radio controlled helicopters are ones that are galvanic or nitro powered. Their low cost coupled with great doing is the speculate for their weighty popularity. You can buy these galvanic Rc helicopters in kits ready from assorted manufacturers and it takes in the middle of 5 to 20 hours to assemble them.
Nitro: These models use a mixture or nitro ethanol and methanol for internal combustion. They are ready in assorted sizes fluctuating from 15 to 90; any way these numbers are not indicative of the rotor span but rather they stand for the nitro machine used in the model. The higher the number, the larger the engine; this means more power to turn larger rotor blades which in turn equates to a bigger over all size of the helicopter.
Electric: even though galvanic Rc helicopters are a fairly up-to-date introduction in the market, they have gained overwhelming popularity and are now seen more ordinarily than the nitro powered models. Thee models use lithium polymer batteries for power which contribute the high voltage required to maintain flight during aerobatic maneuvers without expanding the weight of the model. Depending on the size of the aircraft and the type of battery used, these helicopters can stay in the air for 4 to 12 minuets.
Even though galvanic recreational aircraft models have been ready for quite a few years, they were primarily used indoors due to miniature power, small size and no exhaust fumes. But the newer generations of galvanic Rc helicopters are quiet and have more agility for aerobatic maneuvers.
You can convert nitro powered radio controlled helicopters into galvanic powered models with the help of home made kits. These models are typically made from plastic, aluminum, glass reinforced plastic or carbon fiber. The rotor blades are made from fiberglass wood or carbon fiber. You have to be particularly meticulous while assembling these aircrafts because helicopters are more susceptible to vibrations than fixed wing aircrafts.
Apart from the recreational aspect complicated in the use of these small galvanic Rc helicopters, they can also be used for low altitude photography, remote inspection and observation, policing and filming. As a matter of fact, some models of radio controlled helicopters are specifically designed for these purposes.
