WARNINGS ø Battery Charging and Warning …›„… k
As the user of this product, you are solely responsible for operating it in a manner that
does not endanger yourself and others or result in damage to the product or the property
of others.This model is controlled by a radio signal that is subject to interference from many
sources outside your control. This interference can cause momentary loss of control so it is
advisable to always keep a safe distance in all directions around your model, as this margin
will help to avoid collisions or injury.
1. Never operate your model with low transmitter batteries.
2. Avoid operating your model in the street where injury or damage can occur.Always
operate your model in an open area away from cars, traffic, or people.Never operate
the model out into the street or populated areas for any reason.
3. Carefully follow the directions and warnings for this and any optional support equipment
(chargers, rechargeable battery packs, etc.) that you use.
It is important that you only charge the included 3S 11.1V 2200mAh Li-Po Battery with the
included 3S 11.1V 1.0-Amp Li-Po Balancing Charger. Your battery is equipped with special
Charge Protection Circuitry and Balance Charge Leads with connector that are only
compatible with this charger. Attempting to charge the battery using another Li-Po charger
or non Li-Po compatible charger could result in serious damage. Please familiarize yourself
thoroughly with the Battery Warnings and Guidelines section before continuing.The
included 3S 11.1V 1.0-Amp Li-Po Balancing Charger will charge a near fully discharged
(not over-discharged) 3S 11.1V 2200mAh Li-Po battery in approximately 1.52.0 hours. In
some cases the charge time may be shorter depending on the actual amount of capacity
left in the battery after a flight. NEVER charge the battery unattended.

Not ic e:
The Li-Po battery included with your e-razor 3D will arrive partially charged. For this
reason the initial charge may only take approximately 3050 minutes.
The charger requires up to 3-Amps of 11.515 Volt DC input power that can be supplied by
the optional AC to 12V DC, 3-Amp Power Supply for convenient charging anywhere an
AC outlet is available. NEVER attempt to power the charger from an AC outlet without the
use of a proper AC to DC adapter/power supply.

CONTROL TEST ! " Ä %
Although each e-razor 3D is control tested at the factory, it is a good idea to test the
controls prior to the first flight to ensure none of the servos, linkages or other parts were
damaged during shipping and handling. Before proceeding, disconnect the three bullet
connectors between the motor and ESC. It is not safe to perform the control test with the
motor connected to the ESC.

idea to have an assistant on hand to help sight the blades. Again, be certain to maintain
a safe distance of (20-25 feet) from the helicopter when checking the tracking of the main
rotor blades.
Once the main rotor blades have been brought up to speed, note which blade is running
low and which blade is running high (by the colored tracking tape).
T he helicopter with main rotor blade all have pitch control links .you only need to turn the
control link to achieve the blade tracking adjustment .certainly the best way is to adjust
both pitch control link at the same time. If you made small adjustment on one rotor blade
,the main rotor blades are still out of track ,you need to adjust another blade ,and repeat
the process to check the blade tracking and make adjustment until both blades run in
track .with proper adjustment ,the helicopter will fly stably and smoothly.

Main Rotor Blade Tracking Adjustment – — `H
Caution: Be sure to maintain a safe distance from the helicopter (2025 feet) when tracking
the main rotor blades.Blade tracking is a critical element to the flight performance of just
about any helicopter, Main rotor blades that are out of track may cause vibration,
instability, and loss of power due to increased drag. Although the main rotor blades of
each e-razor 3D helicopter are tracked at the factory, minor adjustments to blade tracking
may be required after blade changes,linkage adjustments or repairs.To check main rotor
blade tracking and make any required adjustments, please note the following tips:
Before proceeding with the test flight of a new model, or any model to which changes or
repairs have been made, be certain that the main rotor blades have been properly
installed and secured.The main rotor blade mounting bolts should be tightened so that the
blades can pivot in the blade grip when moderate pressure is applied. Never allow the
main rotor blades to swing freely in their grips.
After powering the model on and allowing the ESC and gyro to properly arm and initialize,
bring the main rotor blades of your e-razor 3D up to speed. You can check the blade
tracking either on the ground or in the air at approximately eye level. It might be a good

WARNING 6 7 8 9
RC helicopter is not toys! Incorrect operation may cause serious injury or damage. if you
are a novice pilot we strongly suggest that you should find an experienced pilot in RC
helicopter to assist you.
1. It is absolutely necessary to read the manual of the helicopter before operation ,it is
mandatory to check all control systems and mechanical linkages for proper operation
before every flight .safety first!
2.Since the helicopter fly very fast ,it may cause potential danger ,so the choice of the flight
field is of great importance.
3.Do not fly near crowd, high voltage cables or trees to ensure the safely of yourself and
others.
4.Do not fly in the bad weather such as rainy or thundering to ensure the safety of yourself.
5.It is suggested to fly at an open field for beginners, and fly with the training set to practice
yourself. in this case can the helicopter be protected and damage caused by the improper
operation can be reduced.
