Troubleshooting Guide
(Continued)
Problem
Possible Cause
Solution
Control surface does
not move
Control surface, control horn, linkage or servo damage
Replace or repair damaged parts and adjust controls
Wire damaged or connections loose
Do a check of wires and connections, connect or replace as needed
Transmitter is not bound correctly or the incorrect
airplanes was selected
Re-bind or select correct airplanes in transmitter
Flight battery charge is low
Fully recharge fl ight battery
BEC (Battery Elimination Circuit) of the ESC is damaged
Replace ESC
Controls reversed
Transmitter settings are reversed
Perform the Control Direction Test and adjust the controls on transmitter appropriately
Motor power pulses
then motor loses power
ESC uses default soft Low Voltage Cutoff (LVC)
Recharge fl ight battery or replace battery that is no longer performing
Weather conditions might be too cold
Postpone flight until weather is warmer
Battery is old, worn out, or damaged
Replace battery
Battery C rating might be too low
Use recommended battery
AMA National Model Aircraft Safety Code
Effective January 1, 2014
A. GENERAL
A model aircraft is a non-human-carrying aircraft capable of sustained fl ight in the
atmosphere. It may not exceed limitations of this code and is intended exclusively for
sport, recreation, education and/or competition. All model fl ights must be conducted in
accordance with this safety code and any additional rules specifi c to the fl ying site.
1. Model aircraft will not be fl own:
a. In a careless or reckless manner.
b. At a location where model aircraft activities are prohibited.
3. Model aircraft pilots will:
a. Yield the right of way to all man carrying aircraft.
b. See and avoid all aircraft and a spotter must be used when appropriate
(AMA Document #540-D.)
c. Not fl y higher than approximately 400 feet above ground level within three
(3) miles of an airport, without notifying the airport operator.
d. Not interfere with operations and traffi c patterns at any airport, heliport or
seaplane base except where there is a mixed use agreement.
e. Not exceed a takeoff weight, including fuel, of 55 pounds unless in compliance
with the AMA Large Model Aircraft program. (AMA Document 520-A.)
f. Ensure the aircraft is identifi ed with the name and address or AMA
number of the owner on the inside or affi xed to the outside of the model
aircraft. (This does not apply to model aircraft fl own indoors).
g. Not operate aircraft with metal-blade propellers or with gaseous boosts
except for helicopters operated under the provisions of AMA Document #555.
h. Not operate model aircraft while under the infl uence of alcohol or while using any
drug which could adversely affect the pilot’s ability to safely control the model.
i. Not operate model aircraft carrying pyrotechnic devices which explode
or burn, or any device which propels a projectile or drops any object that
creates a hazard to persons or property.
Exceptions:
• Free Flight fuses or devices that burn producing smoke and are
securely attached to the model aircraft during fl ight.
• Rocket motors (using solid propellant) up to a G-series size may be
used provided they remain attached to the model during fl ight. Model
rockets may be fl own in accordance with the National Model Rocketry
Safety Code but may not be launched from model aircraft.
• Offi cially designated AMA Air Show Teams (AST) are authorized to
use devices and practices as defi ned within the Team AMA Program
Document (AMA Document #718).
j. Not operate a turbine-powered aircraft, unless in compliance with the
AMA turbine regulations. (AMA Document #510-A).
3. Model aircraft will not be fl own in AMA sanctioned events, air shows or
model demonstrations unless:
a. The aircraft, control system and pilot skills have successfully demonstrated
all maneuvers intended or anticipated prior to the specifi c event.
b. An inexperienced pilot is assisted by an experienced pilot.
4. 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.
B. RADIO CONTROL
1. All pilots shall avoid fl ying directly over unprotected people, vessels, vehicles
or structures and shall avoid endangerment of life and property of others
2. A successful radio equipment ground-range check in accordance with
manufacturer’s recommendations will be completed before the fi rst fl ight of
a new or repaired model aircraft.
3. At all fl ying sites a safety line(s) must be established in front of which all
fl ying takes place (AMA Document #706.)
a. Only personnel associated with fl ying the model aircraft are allowed at or
in front of the safety line.
b. At air shows or demonstrations, a straight safety line must be established.
c. An area away from the safety line must be maintained for spectators.
d. Intentional fl ying behind the safety line is prohibited.
4. RC model aircraft must use the 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.
5. RC model aircraft will not operate within three (3) miles of any pre-existing
fl ying site without a frequency-management agreement (AMA Documents
#922 and #923.)
6. With the exception of events fl own under offi cial AMA Competition
Regulations, excluding takeoff and landing, no powered model may be fl own
outdoors closer than 25 feet to any individual, except for the pilot and the
pilot’s helper(s) located at the fl ight line.
7. Under no circumstances may a pilot or other person touch a model aircraft
in fl ight while it is still under power, except to divert it from striking an
individual.
8. RC night fl ying requires a lighting system providing the pilot with a
clear view of the model’s attitude and orientation at all times. Hand-held
illumination systems are inadequate for night fl ying operations.
9. The pilot of a RC model aircraft shall:
a. Maintain control during the entire fl ight, maintaining visual contact
without enhancement other than by corrective lenses prescribed for the
pilot.
b. Fly using the assistance of a camera or First-Person View (FPV) only in
accordance with the procedures outlined in AMA Document #550.
c. Fly using the assistance of autopilot or stabilization system only in
accordance with the procedures outlined in AMA Document #560.
Please see your local or regional modeling association’s guidelines for proper,
safe operation of your model aircraft.
