ALWAYS set charger’s output volts to match battery volts.

ALWAYS charge in a fireproof location.

NEVER trickle charge.

NEVER allow the battery temperature to exceed 150° F
[65° C].

NEVER disassemble or modify pack wiring in any way or
puncture cells.

NEVER discharge below 2.5V per cell.

NEVER place on combustible materials or leave
unattended during charge or discharge.

ALWAYS KEEP OUT OF REACH OF CHILDREN.

Read and abide by the following excerpts from the Academy
of Model Aeronautics Safety Code. For the complete Safety
Code refer to 

Model Aviation magazine, the AMA web site or

the Code that came with your AMA license.

1) I will not fly my model aircraft in sanctioned events, air
shows, or model flying demonstrations until it has been
proven to be airworthy by having been previously,
successfully flight tested.

2) I will not fly my model aircraft higher than approximately
400 feet within 3 miles of an airport without notifying the
airport operator. I will give right-of-way and avoid flying in the
proximity of full-scale aircraft. Where necessary, an observer
shall be utilized to supervise flying to avoid having models
fly in the proximity of full-scale aircraft.

3) Where established, I will abide by the safety rules for the
flying site I use, and I will not willfully and deliberately fly my
models in a careless, reckless and/or dangerous manner.

5) I will not fly my model unless it is identified with my name
and address or AMA number, on or in the model. Note: This
does not apply to models while being flown indoors.

7) I will not operate models with pyrotechnics (any device
that explodes, burns, or propels a projectile of any kind).

1) I will have completed a successful radio equipment ground
check before the first flight of a new or repaired model.

2) I will not fly my model aircraft in the presence of
spectators until I become a qualified flier, unless assisted by
an experienced helper.

3) At all flying sites a straight or curved line(s) must be
established in front of which all flying takes place with the
other side for spectators. Only personnel involved with flying

the aircraft are allowed at or in the front of the flight line.
Intentional flying behind the flight line is prohibited.

4) I will operate my model using only radio control frequencies
currently allowed by the Federal Communications Commission.

5)  I will not knowingly operate my model within three
miles of any pre-existing flying site except in
accordance with the frequency sharing agreement
listed 
(in the complete AMA Safety Code).

9) Under no circumstances may a pilot or other person touch
a powered model in flight; nor should any part of the
model other than the landing gear, intentionally touch
the ground, except while landing
.

1. Check the C.G. according to the measurements

provided in the manual.

2. Be certain the battery and receiver are securely

mounted in the fuse. Simply stuffing them into place
with foam rubber is not sufficient.

3. Extend your receiver antenna and make sure it has a

strain relief inside the fuselage to keep tension off the
solder joint inside the receiver.

4. Balance your model 

laterally as explained in

the instructions.

5. Add a drop of oil to the axles so the wheels will turn freely.

6. Make sure all hinges are securely glued in place.

7. Confirm that all controls operate in the correct direction

and the throws are set up according to the manual.

8. Make sure that all servo arms are secured to the

servos with the screws included with your radio.

9. Secure connections between servo wires and

Y-connectors or servo extensions, and the connection
between your battery pack and the on/off switch with
vinyl tape, heat-shrink tubing or special clips suitable
for that purpose.

10. Balance your propeller (and spare propellers).

11. Tighten the propeller nut and spinner.

12. Place your name, address, AMA number and

telephone number on or inside your model.

13. If you wish to photograph your model, do so before

your first flight.

14. Range check your radio when you get to the flying field.

During the last few moments of preparation your mind may
be elsewhere anticipating the excitement of the first flight.
Because of this, you may be more likely to overlook certain
checks and procedures that should be performed before the
model is flown. To help avoid this, a check list is provided to
make sure these important areas are not overlooked. Many
are covered in the instruction manual, so where appropriate,
refer to the manual for complete instructions. Be sure to
check the items off as they are completed.
