Information About the Types of Radio Control RC HelicoptersConventional Electric RC Helicopter Types:Most radio control rc helicopters use a common layout, with one main rotor generating lift, and one tail rotor. This is called the Sikorsky layout. When the rc heli's main rotor turns, it generates torque which causes the helicopter to rotate in the opposite direction. This is countered with a vertically mounted tail rotor. By varying the thrust produced by the tail rotor, the RC heli can remain in one position, or rotate clockwise or counter-clockwise. RC Helicopters With Contra-Rotating and Co-Axial Rotor Blades:An RC helicopter using a contra-rotating system will have two rotors spinning in opposite directions. The torque generated by the rotor blades is canceled out, and the rc helicopter will not require a tail rotor to keep it from spinning. This allows the rc helicopter's tail boom to be eliminated, saving weight. One possible layout has one rotor blade mounted at each end of a long fuselage, as it is for the Boeing CH-47 Chinook, and is known as a tandem rotor. Alternatively, both contra-rotating rotors can be placed on the same shaft, resulting in a co-axial design. Co-axial rc helicopters are very stable and easy to fly. The Bladerunner series indoor rc helicopters use co-axial designed rotor blades. RC Helicopters With Multi-Rotor Design:It is possible for an RC heli to use more that two main rotor blades. The thrust from all the RC helicopter's rotors is combined to generate lift, and the thrust produced by each rotor can be varied to allow the RC heli to maneuver. Decreasing thrust on rotors near the front will cause the RC helicopter to tilt forward and move in that direction. The same method can be used to allow the RC helicopter to move backward and side to side. Draganflyer RC Helicopters use multi-rotor design.

For a long time, the rc heli of choice had been a gas rc helicopter. However, with the introduction of high power lithium batteries it is easy to find electric rc helicopters that match or exceed the performance of gas rc helicopters. With electric rc helicopters you also have the advantage of eliminating the mess of fuel, the hazard of breathing in exhaust gases, and the excessive noise.
Electric rc helicopters also give you the freedom of indoor use. This has made small toy electric rc helicopters possible. The most popular of these is the tiny infrared controlled palm sized Mini Heli electric rc helicopter, and its cousin the Mini Bell electric rc helicopter which is a detailed miniature scale model of a Bell helicopter. The use of lithium batteries as the power source for these electric rc helicopters has made it possible to get light weight and long runtimes.
Because typical electric rc helicopters are smaller and lighter than comparable gas rc helicopters, they are also much safer. The lower weight of electric rc helicopters means that you need less thrust to keep them in the air, and that allows smaller rotor blades that store less kinetic energy and have less inertia. Electric rc helicopters are much less likely to cause personal injury than the relatively heavy blades used on gas rc helicopters. Less weight also tends to reduce the damage caused by a crash. Unlike electric rc helicopters, large gas rc helicopters typically have enough inertia to tear themself apart during a crash. At the opposite end of the spectrum, tiny indoor infrared electric rc helicopters are so light that they just bounce off of objects rather that breaking.
You can also get electric rc helicopters in an RTF (Ready To Fly) kits that requires simply charging the batteries before flying. Gone are the concerns about properly breaking in your gas engine. With electric rc helicopters you gain safety and convenience. Try an electric rc helicopter today.
