General Notes

Radio controlled models are a great source of pleasure. 

Unfortunately, they can also pose a potential hazard if not 

operated and maintained properly.

It is imperative to install your radio control system correctly. 

Additionally, your level of piloting competency must be 

high enough to ensure that you are able to control your 

aircraft under all conditions. If you are a newcomer to radio 

controlled flying, please seek help from an experienced pilot 

or your local hobby store.

Safety Do’s and Don’ts for Pilots

•  Ensure that your batteries have been properly charged

prior to your initial flight.

•  Keep track of the time the system is turned on so you

will know how long you can safely operate your system.

•  Perform a ground range check prior to the initial flight

of the day. See the “Daily Flight Checks Section” for 

information.

•  Check all control surfaces prior to each takeoff.
•  Do not fly your model near spectators, parking areas or

any other area that could result in injury to people or 

damage of property.

•  Do not fly during adverse weather conditions. Poor

visibility can cause disorientation and loss of  

control of your aircraft. Strong winds can cause similar 

problems.

•  Do not point the transmitter antenna directly toward the

model. The radiation pattern from the tip of the antenna 

is inherently low.

•  Do not take chances. If at any time during flight you

observe any erratic or abnormal operation, land 

immediately and do not resume flight until the cause of 

the problem has been ascertained and corrected. Safety 

can never be taken lightly.

Federal Aviation Administration

Purpose

This advisory outlines safety standards for operations of 

model aircraft. We encourage voluntary compliance  

with these standards.

Background

Attention has been drawn to the increase in model aircraft 

operation. There is a need for added caution when operating 

free flight and radio controlled craft in order to avoid 

creating a noise nuisance or a potential hazard to full-scale 

aircraft and persons and/or property on the surface.

Operating Standards

Modelers generally are concerned with safety and exercise 

good judgment when flying model aircraft. However, in 

the interest of safer skies, we encourage operators of 

radio controlled and free flight models to comply with the 

following standards:

a.  Exercise vigilance in locating full-scale aircraft (get help 

if possible) so as not to create a collision hazard.

b.  Select an operating site at sufficient distance from 

populated areas so you do not create a noise problem or 

a potential hazard.

c.  Do not fly higher than 400 feet above the surface.
d.  Always operate more than three miles from the 

boundary of an airport unless you are given permission 

to be closer by the appropriate air traffic control facility 

in the case of an airport for which a control zone has 

been designated or by the airport manager in the case of 

other airports.

e.  Do not hesitate to ask for assistance in complying with 

these guidelines at the airport traffic control tower or 

air route traffic control center nearest the site of your 

proposed operation.

Daily Flight Checks

1.  Check the battery voltage on both the transmitter and 

the receiver battery packs. Do not fly below 4.7V on the

transmitter or below 4.7V on the receiver. To do so can

crash your aircraft.

note: When you check these batteries, ensure that 

you have the polarities correct on your expanded scale 

voltmeter.

2.  Check all hardware (linkages, screws, nuts, and bolts) 

prior to each day’s flight. Be sure that binding does not 

occur and that all parts are properly secured.

3.  Ensure that all surfaces are moving in the proper

manner.

4.  Perform a ground range check before each day’s flying 

session.

5.  Prior to starting your aircraft, turn off your transmitter, 

then turn it back on. Do this each time you start your 

aircraft. If any critical switches are on without your 

knowledge, the transmitter alarm will warn you at this 

time.

6.  Check that all trim levers are in the proper location.
7.  All servo pigtails and switch harness plugs should

be secured in the receiver. Make sure that the switch 

harness moves freely in both directions.
