Ready-to-Fly Electric Helicopter
R/C helicopter is not too expensive as you think. In less than
two hundred US dollar, you can get a ready-to-fly R/C helicopter and
enjoy the fun of flight right away!! Aerohawk is one of the most
popular mini-helicopter in the market. Everything you need is included
in it's kit, like rechargable battery, charger, 4 channels radio set,
servos & receiver. Full replacement parts are also available
in rcMart.com, so it is worry-free
for breaking any part during your first flight lesson.
Introduction :
This is a newly designed electric mini-helicopter model. The latest technology and
the first-class skills ensure the excellent performance of the electric helicopter even
when the standard 4-channel remote transmitter is used, so it becomes one of aircrafts that can
fly outdoors when it is windless. It is not difficult to operate this Aerohawk helicopter, but
you should take a great caution and make a good deal of practice when you are controlling the
flying of Aerohawk. The frequent practice will result in a skillful control on the helicopter.
The Aerohawk is the advanced version of the Skylark. Its been optimised for performance.
The basic Helicopter is Lighter the chassis has been redisigned to prevent movement and
flex. The Aerohawk is very responsive and very quick to follow inputs for the pilot. As
with the Skylark the Helicopter comes complete with Full topqualits RC Equipment, Charger
and Battery. The helicopter is built, only requiring Minor assembly and setup prior to
first flight. Its a great helicopter very well made and very enjoyable. There is a host
of upgrades comming for the Aerohawk

Which is better?
The Skylark or the Aerohawk?
The Skylark is a well established helicopter. Its gentle to fly and very
very robust. Its trade of is in advanced performance and also upgrades
(Most Aerohawk upgrades will be compatible with the Skylark). The Aerohawk
sacrifices some of the robust qualities for performance, Its quicker to take
off, Accelerates and turns quicker
Both the Skylark and the Aerohawk are superb outdoors. There too light
for windy conditions but for hovering in your back garden and zapping round
the garden gnomes they are unbeatable
Any replacement parts?
Yup! Full parts are available at rcMart.com

Principle of Helicopter
The airfoil of the helicopter will produce an ascending force. With the speed-up
of the motor, the main rotary wing will also speed up to a produce a stronger ascending
force. At the same time, a kind of wresting force will also rise with the result of the
rotary wing. The wresting force acts on the airframe to wrest the helicopter evenly.
The tail rotary airfoils are a little slantwise. A kind of pushing force will rise
from the tail rotary airfoils. To change the speed of the tail rotary airfoils is a
way to change the pushing force toward right or left.
Now the two principles to control the helicopter are clearly stated. First, to
increase or to reduce the speed of the main rotary wings is used to control the
flight height of the helicopter; second, to increase or to reduce the speed of the tail
rotary airfoil is used to control the leeway of the helicopter. For a helicopter model,
many operations are to be managed for lateral rolling and nosing down (driving).
These two functions can be controlled by the circulation system, which consists of
the servo, slanting tray, balance wing and main rotary wing. The servo is connected
with the lower exterior tray; the higher interior slanting-tray is relater with the
balance wing. When servo is running, the slanting tray will be sloped: you can make
the slanting tray slope to forward, backward, left or right. Now you can think it as
an U.F.O. In this way, the circulation system will operate the helicopter. For instance,
if you put forward the circulation system, the tray will be sloped forward; the head of
the helicopter will dive to the ground. This is a simple way for you to operate the
helicopter. The circulation system is controlled by two servos: one is to control the
lateral rolling (right and left operation); the other is to control the nosing down (front and back operation).
