     Step 2

Place the airframe upside down on a flat
surface so the trailing edge of the airplane
extends over the edge of your work surface.

Place the servos so the servo arms are
centered in the servo arm openings
And make sure that the larger part of the
case offset is facing the front of the aircraft.   Note: It is important that you NOT use larger

Section 12: Control Throw Recommendations

      Step 1 Control Throws
Give the aircraft a complete check over and
make sure the airframe and all control
surfaces are straight.

Also make sure that with up and down
elevator your elevons stay equal through
their range of motion.

Start out with 1 IN. up & 1 IN. down with both
elevator & aileron, then crank up the elevator
until it starts to stall & crank up the ailerons
until the rolls slow down or YOU YELL
UNCLE.

We recommend that you use 100% expo on
your ailerons and 25% on your elevator for
the test flight.

2007 AMA National Model Aircraft Safety Code

2007 Official Academy of Model Aeronautics National Model Aircraft Safety
Code Effective January 1, 2006

GENERAL
1. A model aircraft shall be defined as a non-human-carrying device capable of sustained
flight in the atmosphere. It shall not exceed limitations established in
this code and is intended to be used exclusively for recreational or competition activity.
2. The maximum takeoff weight of a model aircraft, including fuel, is 55 pounds, except for
those flown under the AMA Experimental Aircraft Rules.
3. I will abide by this Safety Code and all rules established for the flying site I use. I will not
willfully fly my model aircraft in a reckless and/or dangerous
manner.
4. I will not fly my model aircraft in sanctioned events, air shows, or model demonstrations
until it has been proven airworthy.
5. I will not fly my model aircraft higher than approximately 400 feet above ground level,
when within three (3) miles of an airport without notifying the
airport operator. I will yield the right-of-way and avoid flying in the proximity of full-scale
aircraft, utilizing a spotter when appropriate.
6. I will not fly my model aircraft unless it is identified with my name and address, or AMA
number, inside or affixed to the outside of the model aircraft. This
does not apply to model aircraft flown indoors.
7. I will not operate model aircraft with metal-blade propellers or with gaseous boosts
(other than air), nor will I operate model aircraft with fuels containing
tetranitromethane or hydrazine.
8. I will not operate model aircraft carrying pyrotechnic devices which explode or burn, or
any device, which propels a projectile of any kind. Exceptions
include Free Flight fuses or devices that burn producing smoke and are securely attached
to the model aircraft during flight. Rocket motors up to a G-series
size may be used, provided they remain firmly attached to the model aircraft during flight.
Model rockets may be flown in accordance with the National Model
Rocketry Safety Code; however, they may not be launched from model aircraft. Officially
designated AMAAir Show Teams (AST) are authorized to use
devices and practices as defined within the Air Show Advisory Committee Document.
9. I will not operate my model aircraft while under the influence of alcohol or within eight
(8) hours of having consumed alcohol.

                                                                                                      35
10. I will not operate my model aircraft while using any drug which could adversely affect
my ability to safely control my model aircraft.
11. Children under six (6) years old are only allowed on a flightline or in a flight area as a
pilot or while under flight instruction.
12. When and where required by rule, helmets must be properly worn and fastened. They
must be OSHA, DOT, ANSI, SNELL or NOCSAE approved or
comply with comparable standards.

RADIO CONTROL
1. All model flying shall be conducted in a manner to avoid over flight of unprotected
people.
2. I will have completed a successful radio equipment ground-range check before the first
flight of a new or repaired model aircraft.
3. I will not fly my model aircraft in the presence of spectators until I become a proficient
flier, unless I am assisted by an experienced pilot.
4. At all flying sites a safety line or lines must be established, in front of which all flying
takes place. Only personnel associated with flying the model aircraft
are allowed at or in front of the safety line. In the case of airshows or demonstrations a
straight safety line must be established. An area away from the safety
line must be maintained for spectators. Intentional flying behind the safety line is
prohibited.
5. I will operate my model aircraft using only radio-control frequencies currently allowed by
the Federal Communications Commission (FCC). Only
individuals properly licensed by the FCC are authorized to operate equipment on Amateur
Band frequencies.
6. I will not knowingly operate my model aircraft within three (3) miles of any preexisting
flying site without a frequency-management agreement. A
frequency-management agreement may be an allocation of frequencies for each site, a
day-use agreement between sites, or testing which determines that no
interference exists. A frequency-management agreement may exist between two or more
AMA chartered clubs, AMA clubs and individual AMA members, or
individual AMA members. Frequency-management agreements, including an interference
test report if the agreement indicates no interference exists, will be
signed by all parties and copies provided to AMA Headquarters.
7. With the exception of events flown under official AMA Competition Regulations rules,
excluding takeoff and landing, no powered model may be flown
outdoors closer than 25 feet to any individual, except for the pilot and the pilot's helper(s)
located at the flightline.
36
8. Under no circumstances may a pilot or other person touch a model aircraft in flight while
it is still under power, except to divert it from striking an
individual.
9. Radio-controlled night flying is limited to low-performance model aircraft (less than 100
mph). The model aircraft must be equipped with a lighting system
which clearly defines the aircraft's attitude and direction at all times.
10. The operator of a radio-controlled model aircraft shall control it during the entire flight,
maintaining visual contact without enhancement other than by
corrective lenses that are prescribed for the pilot. No model aircraft shall be equipped with
devices which allow it to be flown to a selected location which is
beyond the visual range of the pilot.

FREE FLIGHT
1. I will not launch my model aircraft unless I am at least 100 feet downwind of spectators
and automobile parking.
2. I will not fly my model aircraft unless the launch area is clear of all individuals except my
mechanic, officials, and other fliers.
3. I will use an effective device to extinguish any fuse on the model aircraft after the fuse
has completed its function.

CONTROL LINE
1. I will subject my complete control system (including the safety thong where applicable)
to an inspection and pull test prior to flying. The pull test will be in
accordance with the current Competition Regulations for the applicable model aircraft
category. Model aircraft not fitting a specific category shall use those
pull-test requirements as indicated for Control Line Precision Aerobatics.
2. I will ensure that my flying area is clear of all utility wires or poles and I will not fly a
model aircraft closer than 50 feet to any above-ground electric utility
lines.
3. I will ensure that my flying area is clear of all nonessential participants and spectators
before permitting my engine to be started.
