Get Started on Your Dream of Flying an Aircraft by Using Remote Control Helicopters


People who once spent their childhood dreaming of one day flying an aircraft can now take up this hobby.  They can start with the easily affordable remote control helicopters.  One does not need to be a flight engineer, or a pilot to do this as children and adults alike are now turning to these fun stuff to get their thrills in life.  Anyone wondering why the sales of these gadgets are shooting up to the roof, this is the answer.  The hobby aircrafts come in all sizes to suit the needs of individuals.  In fact, some are small enough to be held by one hand, but there are also the larger sizes.  They can run on gas or nitro, and there are those that use electricity to recharge their batteries. 

The large, remote control helicopters that used to be run on nitro gas have modified parts that are now using electric powered motors.  The gas used to produce a nasty smell and noisy sound, but now the recent modifications have ensured that the aircraft can fly around the neighborhood without causing a nuisance to the neighbors.  There has been a lot of work going on towards reinventing these fun gadgets.  In fact, most of the original parts of the old names have improved to provide more convenience and greater maneuverability when flying these kits.

For example, the technology used in producing the radio controlled machines has adjustments to incorporate coaxial design that is suitable for beginners.  The modification provides for easy flying techniques.  The helicopter had become more stable than it used to be when it had one rotor design that consisted of a tail rotor.  The modification in the current remote control helicopters involves a coaxial firm rotor that has firm, pitch blades and one swash-plate. They control the cyclic pitch of the bottom rotor blade.  Then the rotor blade that takes its position on the upper side is not mechanically controllable.  It only stabilizes through inertia by using a set of counterweights, or a fly-bar.  This mechanism works perfectly by the fact that the overall pitch mechanism obtained on both rotors, on two different motors applied.  The result is the differential change of speed between the two motors. 

This design of remote control helicopters does away with the complexity that used to be a single swash-plate and no collective pitch style was in place.  The design is practical and suitable for the production of the machines on mass for commercial purposes.  Another advantage of using this system is for the relatively easier manner the product can be handled when in operation as the helicopter becomes easy to control.  The cons that have come up with this modification are several.  For example, this model with basic mechanical form of remote control helicopters has created a couple of limitations.  The limitations are in aerobatic ability and maneuverability due to greater risks of the blades colliding during stunts and difficult moves.  The pilot has no upper hand when trying to control the rotation of the upper blades as he can with the lower ones that are directly controllable by him.
