Use fine sandpaper to remove imperfections along the
edges of the propeller. For the best performance, use a Top
Flite Precision Magnetic Prop Balancer

(TOPQ5700) to

balance the propellers (this is a necessity on glow-powered
engines, but less critical on small electric models).

1.  Using multiple battery packs for successive flights may
cause the motor to become excessively hot, thus causing
damage. Allow the motor to cool for at least 10 minutes
between flights.

2.  The ideal power source for the BLT system is a 6 to
7-cell (7.2 - 8.4 volt) battery pack. The use of a higher
voltage battery may reduce motor life.

If taking off from the ground, the wheels must spin freely.
Check the wheels for binding when moved from side to side
and put a drop of oil on each axle.

Note:

Failure to follow these safety precautions may result

in severe injury to yourself and others.

Get help from an experienced pilot when learning to 
operate motors.

Use safety glasses when running motors.

Do not run the motor in an area of loose gravel or sand; the
propeller may throw such material in your face or eyes.

Keep your face and body as well as all spectators away
from the path of the propeller as you start and run the motor.

Keep items such as these away from the prop: loose
clothing, shirt sleeves, ties, scarfs, long hair or loose objects
(pencils, screw drivers) that may fall out of shirt or jacket
pockets into the prop.

The electric motor and motor battery used in your Basic Light
Trainer is very powerful and the spinning propeller has a lot of
momentum; therefore, if you touch the propeller while it is
spinning it may inflict severe injury. Keep this in mind, respect
the motor and propeller for the damage it is capable of and take
whatever precautions are necessary to avoid injury. Always
disconnect and remove the motor battery until you are ready to
fly again and 

always make sure the switches are turned off

before connecting the battery.

Read and abide by the following Academy of Model
Aeronautics Official Safety Code:

GENERAL

1. I will not fly my model aircraft in competition or in the
presence of spectators 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 to 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.

7. I will not fly my model unless it is identified with my name
and address or AMA number, on or in the model.

RADIO CONTROL

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 flyer, unless assisted
by an experienced helper.

3. I will perform my initial turn after takeoff away from the pit,
spectator and parking areas and I will not thereafter perform
maneuvers, flights of any sort or landing approaches over a
pit, spectator or parking area.

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

Though the BLT is a “Park Flyer,” the 

best

place to fly 

any

model is at an AMA chartered club field. Club fields are
designed for R/C flying making your outing safer and more
enjoyable. We recommend that you join the AMA and a
local club so you can have a safe place to fly and have
insurance to cover you in case of a flying accident. The
AMA address and telephone number are in the front of this
manual. 

If there is no club or R/C flying field in your area, find a
suitable site that is clear of trees, telephone poles,
buildings, towers, busy streets and other obstacles. Since
you are not flying at a sanctioned AMA site, be aware that
