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.
IMAA SAFETY CODE ( EXCERPTS )
Since the Cessna 310 qualifies as a “giant scale”
model and is therefore eligible to fly in IMAA
events, we’ve printed excerpts from the IMAA
Safety Code which follows.
What is Giant Scale?
The concept of large or giant-scale is generally
considered to apply to radio controlled model aircraft
with minimum wingspans of 80 inches for monoplanes
and 60 inches for multi-wing aircraft. Quarter-scale or
larger replicas of person-carrying aircraft with proper
documentation (minimum 3-view drawing) which do
not fit the size requirements will also be permitted.
Section 1.0: SAFETY STANDARD
1.1 Adherence to Code: The purpose of this Safety
Code is to provide a structure whereby all
participants, including spectators, will be aware of
the inherent dangers in the operation of radio
controlled aircraft. This code is meant to serve as a
minimum guideline to all participants. It is
understood that the ultimate responsibility for the
safety of any aircraft lies with the owner(s), pilot(s)
and spectator(s) involved in any event. It is the
responsibility of all participants to exercise caution
when operating, or observing the operation of all
radio controlled aircraft. The pilot/owner of an
aircraft will not be dissuaded from taking whatever
steps they deem necessary, in addition to this
code, to insure that their aircraft is safe.
1.2 The most current AMA Safety Code in effect is to
be observed.
Section 3.0: SAFETY REVIEW
3.4 Flight Testing: All aircraft are to have been flight
tested and flight trimmed with a minimum of six
(6) flights before the model is allowed to fly at an
IMAA Sanctioned event.
3.5 Proof of Flight: The completing and signing of the
Declaration section of the Safety Review form (see
Section 3.2) by the pilot (or owner) shall
document, as fact, that the noted aircraft has been
successfully flight tested and proven airworthy
prior to the IMAA event.
Section 4.0: SPOTTER/HELPER
4.1 Spotter/Helper Definition: An assistant to aid the
pilot during start-up, and taxing onto the runway.
The spotter/helper will assist the pilot in completing
a safe flight.
4.2 Each pilot is required to have a spotter/helper at all
IMAA sanctioned events. The event Safety
Committee should be prepared to assist those
pilots who do not have a spotter/helper to make
sure that every registered pilot has the opportunity
to fly at a sanctioned event.
Section 5.0: EMERGENCY ENGINE SHUT OFF
(Kill Switch)
5.1 Magneto spark ignition engines must have a coil-
grounding switch on the aircraft to stop the engine.
This will also prevent accidental starting of the
engine. This switch shall be readily available to both
pilot and spotter/helper. This switch is to be operated
manually and without the use of the Radio System.
5.2 Engines with battery powered ignition systems
must have a switch to turn off the power from the
battery pack to disable the engine from firing. This
will also prevent accidental starting of the engine.
This switch shall be readily available to both pilot
and spotter/helper. This switch shall be operated
manually and without the use of the Radio System.
5.3 There must also be a means to stop the engine from
the transmitter. The most common method is to
completely close the carburetor throat using throttle
trim, however other methods are acceptable. This
requirement applies to all glow/gas ignition engines
regardless of size.
Section 6.0: RADIO REQUIREMENTS
6.1 All transmitters must be FCC type certified.
6.2 FCC Technician or higher-class license required
for 6 meter band operation only.
ADDITIONAL IMAA GENERAL
RECOMMENDATIONS
The following recommendations are included in the
Safety Code not to police such items, but rather to
offer basic suggestions for enhanced safety. It is
expected that IMAA members will avail themselves of
technological advances as such become available, to
promote the safety of all aircraft and participants.
• Servos need to be of a rating capable to handle the
loads that the control surfaces impose upon the
servos. Standard servos are not recommended for
control surfaces. Servos should be rated heavy-duty
ounces of torque. For flight critical control functions
a minimum of 45 inch/ounces of torque should be
