The main purpose is
to get the optimum
performance under
manual mode in this
adjustment. Pleas Never
try to shift to auto mode
when flying.
4 Outdoors Flying Adjustment
Please read through this chapter before flying outdoors. Peruse 【4.5 Points for
Attention in Flying】 before flight. Please operate carefully to avoid any accident！
4.1 Helicopter Flying Adjustment and Test under Manual Mode
1)
Test the RC antenna’s radio distance: take
down the main blades and turn on the
engine at the first test; then shorten the
antenna, do the test about 20m away from
the helicopter under manual mode. If the
green LED enters the auto mode, which is
sparkle, it indicates that RC is out of range.
Now, the user need to check if the installation
positions of Adapter and RC receiver are far away from interference sources
as engine, especially the gasoline engine.
2)
After completing the installation and adjustment as an ordinary
remote-control helicopter, users can process the complete flying
adjustment under the manual mode and reach the stable flight
performance

.
3)
Keep the helicopter stable temporarily even if the helicopter is not in control
ling for seconds by tuning the trimming of RC. Now, users need to remember
the general position of PITCH stick

1 :
With the inertial system in the control system, vibration of helicopter will cause the control of the
Main Controller to be at an unstable state. So, to display the best performance of the whole system,
users need to reduce the vibration to the smallest
。
¾
Balance the main rotor to avoid “twin screw phenomenon”. Users need to adjust the
helicopter to a condition which it is almost impossible to notice the vibration by naked eyes.
¾
Adjust the mechanical center point of helicopter, especially tail rotor. Under the unlocking
mode of the helicopter’s gyro, adjust the mechanical center point of the tail rotor. When
hands off the stick, no obvious rotation is allowed and guarantee of helicopter’s temporary
hovering is needed.
¾
Push the rudder stick to the left/right endpoint and ensure the rotation speed of tail at 1
circle per 2 seconds in left/right direction. After the adjustment, users can switch it to the
locking mode of gyro.
