Facts about Electric - Battery - RC Helicopters
An electric or battery operated helicopter is just one of the most common types of RC helicopters available in the market.
At one time, it has been used mostly indoors. But bigger electric helicopters appropriate for outdoor activities and
complex aerobics have started gaining status. Electric helicopter are noted for its silence making it a popular choice
especially for those who are near residential areas and places where noise is strictly controlled like Germany.A
single-rotor R/C helicopter consists of a main and tail rotor. The 2 rotors work together to control the stability and
maneuverability of the helicopter. Many pilots who are proficient in flying a dual-rotor or coaxial rotor R/C helicopters
find single-rotor models a little different.
Underlying Theory
Majority of electric helicopter throttles feature an integrated governor mode. You can opt to direct the throttle without
using the standard throttle control of the radio. Electric helicopters are very steady in a hover mode due to the stable
electric power output. It does not involve a clutch.
The usual electric helicopter includes 4 servos. Each of these servos can use fairly amount of current. The Battery
Eliminator Circuit (BEC) must have adequate capacity to provide enough current for all servos working at the same time.
The BEC is usually built within the speed controls to prevent weight of receiver batteries. Larger electric helicopters
have started using separate, high voltage “Ultimate BEC”.
New materials for motor batteries have also been discovered. One of the most recent that has proven remarkable results is
the lithium chemistries. For the most part of various helicopter functions, it is still not recommended. NiCad’s are still
preferred due to its reliability and cost efficiency. It charges faster and provides higher currents with no difficulty.A

A lot of helicopter enthusiasts have recommended electric R/C models for beginners. It is easier to fly and you do not
have to worry that much on some technical issues. Regardless of your interests and level expertise on R/C helicopters, you
will find no few reasons at all not to like electric types.
Trivia:
The world’s smallest remote-controlled production model electric helicopter is the Picoo Z according to the Guinness World
Records 2006. It costs $30 and sold in various toy stores, electronic shops, and online stores. Mosquito follows on the
list which is a counter-rotating blade battery-operated R/C helicopter.
The world’s smallest non-production R/C electric helicopter is the Micro Flying Robot developed by Seiko Epson in November
2003 for the International Robot Exhibition in Tokyo. Its stands at 2.8 inches (70 millimeters) and weighs 0.31 ounces
(8.9 grams). It includes 2 microprocessors, a gyro-sensor, Bluetooth module, image sensor and an accelerometer.A
