Introduction
Thank you for purchasing our product. We strongly recommend that you read the whole user manual before you
fly your helicopter. This will make it easier and safer as you will be given a full explanation of how the helicopter
works, and how to use the control transmitter.
Keep the manual as a future reference book for maintenance and adjustment.
Also be aware that this model helicopter is meant for indoor use under draught-free conditions.
Outdoor use is not recommended, but if done, only fly when there is ABSOLUTELY NO WIND.
Warning
1. The HM 5G4 helicopter is not a toy, and it is designed for
indoor
use.
With its complex combinations of electronics, mechanics, and aerodynamics it requires proper setup and
adjustment to be used to it full potential, and to avoid accidents. Although it is adjusted from the factory you
should always check it as outlined in this Instruction Manual.
We accept no liability for damage and consequent damage arising from the use of the products, because we
have no control over the way they are installed, used, and operated.
If you fly in a room containing valuables, be aware that if you don’t possess the required flying skills and
control of the helicopter, you can create a lot of damage!
2. Before you charge the Li-Po battery, please read the instructions on page 5.
Use only the supplied charger unless you have other dedicated Li-Po charger, and know how to use it. Do not
overcharge. Overcharging may result in fire or explosion. If the battery gets hot during charging, STOP
CHARGING AT ONCE. NEVER short circuit the battery! It packs a lot of energy and may explode or ignite.
The battery must be properly disposed of.
3. Children under 14 years old must only fly the helicopter under a competent adult pilot’s supervision.
Notice: Please let the motors cool for 10 minutes after each flight of a fully charged battery pack. That will
allow the motors to cool down as they otherwise risk overheating, and start burning or be damaged.
Please READ THIS BEFORE CHARGING THE Li-Po Battery:
ALWAYS use the supplied approved Li-Po charger, or a Li-Po approved charger.
NEVER charge over 4.25V per cell
NEVER charge at currents greater than 1C (C = battery capacity in Ah or mAh)
NEVER trickle charge
NEVER charge dissimilar or unmatched packs in series or with any difference in cell type, cell capacity, pack
capacity or charge state (±0.03V per cell). If in doubt, charge cells separately.
NEVER allow to Discharge below 3.0V per cell
NEVER expose pack to intense heat or prolonged exposure to elevated temperature
NEVER continue charging if any part of pack gets warm (Li-Po packs should not heat up during charging)
NEVER charge a pack at sub-zero temperatures
NEVER disassemble or modify pack wiring in any way, or puncture cells
NEVER place on combustible materials or leave unattended during charging
NEVER charge a pack that is under voltage after recovery (under 3.0V per cell)
ALWAYS charge in a fireproof location
ALWAYS set charger's output voltage to match battery voltage if using other than supplied charger
