Test Comment:
1. I have tried the stock NIMH battery, not very good. Very short in
flying - about 5 minutes after the battery fully charged. NOT
RECOMMEND.

2. 2200mah battery is kind of big, so do not use that in test. The
2200mah battery can not fit the helicopter battery holder. Need to
attached it under the battery holder. So not very good.

3. Tried the li-ion 1800mah battery, very good result - lift up the
helicopter very fast and hovering is very stable, lot better than I can
expected for this kind of money I spent ($199 when I buy). The
helicopter is very powerful with this battery. The size of the battery
just fit into the battery holder perfectly. RECOMMENDED.

Others:
This helicopter need some setting and trimming when Irecieved it. Need
to trim the helicopter to make it fly better. I also adjust the main
blade angle to make it hovering better in air.

no. 8 dip switch on the back of the transmitter, and adjust the PLT and
PZT to find the correct and most stable angle, so you can lift up the
helicopter into air fast and fly it more stable. It will take you some
time to find the correct angle - you can hold it in hand to feel the
lift up power to find the good angle. Try it couple time and you should
have some sense of finding the correct angle.

Li-ion Battery Charging: Be careful with the li-ion battery charging.
When you are charging the li-ion battery, pay attention to it. When
light change on the charger (GREEN), disconnet the battery to avoid any
damage to the battery. I have blow up a li-ion battery. So be careful
with that.

Before you fly: Check the helicopter careful to make sure all parts are
good and tight. This will avoid some accident. Do not get one yet, but
my experience in nitro helicopter tought me that.

Battery charging caution: For li-ion battery, before yo charge the
battery, you must make sure there is not damage on the battery,
especially if you crash the helicopter. Make sure the battery is good
and not damage before charge. A battery can be damage in result of
crash. Charging a damaged battery can be very very danger, it may blow
up (FIRE). So always be careful with that. Li-ion and li-po battery is
the very high powerful battery, so be safe.

Flying time: Try to take a break to let the motor cool down when the
motor get hot. I have burned out 1 motor already, because it is very
very hot when I fly the heli for very long time. So be careful of the
flying time and let the motor cool down, so you can save some money to
buy a new motor.

Overall: Good helicopter for it's low price. Better than I expected.
Not as powerful as the nitro heli. But worth it to buy one if your
budget is limited.
