Do not be fooled it is NOT easy to fly R/C Helicopters
It may look easy when watching an experienced pilot flying his model, but perseverance and hours of practice will be needed before
you will be able to fly and opperate the model safely. RJX HOBBY suggests you join a club or seek help from an experienced pilot to
assist you in your first test flights and then as with all things the more you practice the better you will become. We encourage you to
practice often and enjoy the experience of RC rotary flight!
WARNING
LiPo batteries need special care. Improper handeling or charging can cause fire and damage to your Helicopter and yourself. Contact
your dealer or supplier for more information.
1. Check your charger settings before charging your LiPo battery to insure they are correct for the specifications of the battery.
2. We recommend storing and charging LiPo batteries in a lipo sack or porcelain container." If kept in a metal container or ammo
case, explosion could occur if these cases are sealed and gases are not allowed to vent. We recommand to use the original
LipoSack from the USA since it has been actually designed and tested by a firefighter to contain the jet flames discharged from
a failing lipo battery.
3. Please keep LiPo Batteries away from sources of heat..
4. Never store LiPo Batteries fully charged. Check the information on your batteries.
5. NEVER SHORT OUT LiPo Battery wires.
6. Before conecting your LiPo battery to the Helicopter,make sure your transmitter is turned ON and all sticks and switches are
set properly.

This manual contains the detailed instructions to build and set up the X-Tron 500FBL. Please follow it to ensure that you
achieve the best performance and mechanical integrity from your finished kit. For those of you who already have
experience with model helicopters, we still suggest that you assemble and adjust your model according to these
instructions for the best results. Please keep your copy of this manual in a safe place and refer to it when replacing
spare parts or upgrading.
Remove oil and grease then apply threadlock. (This applies throughout the manual)
Remove oil and grease. (This applies throughout the manual)
Please refer to the list at the end of this instruction manual when you need spare parts.
Regardless how tight the nuts, bolts and screws are tightened, they will still slowly come loose over a period of time
due to vibration from the helicopter. Should this happen the helicopter will become out of control or severely damaged
causing a very potential dangerouse situation.
We strongly recommend that you apply threadlock to any nuts, bolts or screws that are indicated by these signs.
There are two types of threadlock, blue (medium) and red (hard) . Use blue threadlock on screws
that have to be removed regularly and red threadlock for screws that should be fixed permanently. Clean them
with Alcohol (or similar) before you apply the threadlock.
