Press Release Summary = Electric RC helicopter

Press Release Body = In recent years, electric rc helicopter have really dropped in
price and have become easier to fly, making electric rc helicopter the ultimate
\'must have\' radio control model. Electric RC helicopter allows more people to enjoy
this hobby without having to always fix their models and having to pay a hefty
price.

As a result, electric rc helicopter now make up the fastest growing sector of the
general hobby of rc flying, and the models shown on this page are just a few of the
most popular models at the current time.

So it\'s great news if you\'ve ever loved the idea of flying a model helicopter but
have always been put off by the high prices and horror stories about how hard model
helicopters are to control - it seems that those days are over!

Having said that though, care still needs to be taken if learning to fly a 4 or more
channel single rotor electric rc helicopter from scratch. electric rc helicopter not
toys and they do still have a learning curve! The co-axial electric rc helicopter,
talked about further down the page, are much easier to fly with no experience.

But many modern electric rc helicopters such as the sleek-looking Phoenix CP,
pictured below, are designed with the novice, as well as the expert, in mind.
The Phoenix CP follows hot on the heels of the tried and trusted Phoenix CP, one of
the most popular electric rc helicopters in its class*.






Helis like the Blade generally have good flight stability - exactly what you need
when learning to fly an rc helicopter, and yet they\'re perfectly capable of
demanding 3D aerobatic flying with some simple upgrades (and a lot of practice...).

So even if you\'ve never held a radio control helicopter before, a model like the
Blade CP will give you a smooth introduction to flying electric rc helicopters but,
as previously mentioned, you still have a learning curve to deal with!



*Fixed or collective pitch?
The term \'pitch\' refers to the angle of the main rotor blades (and rotor disc) in
relation to the horizontal airflow, but when comparing FP and CP helicopters this
pitch name only refers to altitude control - cyclic control has the same method on
each type of model.

Whether the model is FP or CP is an important factor to consider when choosing an
electric rc helicopter, and the choice largely depends on what sort of flying you
want to do, as well as your budget.

Fixed Pitch (FP) is self-explanatory in that the blade pitch is, well, fixed. The
main blades do not pivot about their longitudinal axis to change pitch angle, (ie
change the amounts of lift) and so altitude (climb/descent) must be controlled by
motor speed - faster turning blades generate more lift, and vice versa.
Generally speaking, FP helicopters are not as responsive in the air and can be a bit
\'twitchy\' at first, until the pilot gets used to the feel of it. They are, however,
cheaper to buy and marginally easier to master.

Collective Pitch (CP) means that the pitch angle of each main rotor blade can be
moved to change the amount of lift generated by them.
The motor is kept at a more constant speed, and the altitude is controlled by
changing this pitch angle of the blades. This makes the helicopter more agile,
responsive and smoother in the air, but gives a steeper learning curve for the pilot
- and they cost more to buy.

The bottom line? If you just want an \'entry-level\' taste of flying an electric rc
helicopter with circuits and hovering, then a FP model will suit your needs very
well. If you can see yourself wanting to fly in a more demanding way, then a CP heli
is much more appropriate for your needs.



Contra-rotating (co-axial) electric rc helicopters
Most electric rc helis follow the conventional helicopter layout with a single main
rotor and tail rotor.
However, there are numerous models around that use two main rotors that turn in
opposite directions to each other and a tail rotor is not used.

Examples are the Esky Lama V3, the Dragongfly 5#8 and Vortex.
These 3 are shown below, respectively:





Latest Version3 Esky LAMA Co-Axial 4CH Electric RC Helicopter RTF

Latest Version3 Esky LAMA Co-Axial Helicopter has come to the market! V3 Lama Flies
stably and silently indoor and outdoor, just as walking in the air. It makes you and
your family to have lots of fun with it together. With double-sharing-one-axis
structure and with stable and silent flight, it is designed for beginners with no
experience , It is easy to learn to fly. You can be familiar with its operation and
enjoy the flying in a short-term. With power supply of Li-polymer battery, it can
fly lighter and longer. Complete set, Ready To Fly. Only requires 8 AA Batteries for
Transmitter.






Walkera Dragongfly 5#8 Co-Axial 4CH Electric RC Helicopter RTF



it is the upgrade aluminum version of the 5#4 R/C Helicopter. Design of metal main
frame, metal swash plate and metal rotor head is of legerity, innovation, precise
and stability. 4 Channel remote control set includes complete Forward/Backward,
Left/Right, Up/Down control (RUDDER, AILERON, ELEVATOR, AND THROTTLE). Perfect for
beginners or for simple indoor fun!!







Vortex 4CH Electric RC Co-axial Mini Helicopter RTF


The Vortex Co-Axial Helicopter. Flies stably and silently indoors and outdoors. The
single-axial counter rotating blades provide a stable and silent flight. This model
is designed for beginners. Package includes a li-poly battery and charger (A/C
adapter for the charger is included under the foam packing). The Li-poly battery
enables it to fly lighter and longer. Complete set, Ready to Fly. Only requires 8 AA
Batteries for the transmitter. Package also includes an extra set of 2 upper and 2
lower blades.





Because the two main rotors spin in opposite directions to one another, they cancel
out each other\'s torque and so a tail rotor is not necessary on these kind of
helicopters - that\'s one less channel to worry about when learning to fly!
These contra-rotating helicopters are very stable in the air and can be flown around
just like a conventional tail rotor model.

They have the added advantage of being a lot easier to master, and the good ones
such as the Blade CX shown above can pretty much be flown right out the box with not
much setting up involved.
In comparison, a single rotor/tail rotor RTF electric heli advertised as \"Can be
flown straight from the box with NO experience!\" invariably needs some tweaking here
and there, and some sensible practice.



With the majority of electric rc helicopters, so long as you are sensible and follow
the manufacturer\'s instructions closely, there is absolutely no reason why you
should have any serious problems or difficulties with learning to fly your
helicopter quickly and safely.
