Make all engine adjustments from behind the rotating 
propeller.

The engine gets hot! Do not touch it during or right after 

operation. Make sure fuel lines are in good condition so fuel 
will not leak onto a hot engine, causing a fi re.

To stop a glow engine, cut off the fuel supply by closing 

off the fuel line or following the engine manufacturer’s 
recommendations. Do not use hands, fi ngers or any other 
body part to try to stop the engine. To stop a gasoline 
powered engine an on/off switch should be connected to 
the engine coil. Do not throw anything into the propeller of a 
running engine. 

AMA SAFETY CODE (excerpts)

Read and abide by the following excerpts from the Academy 
of Model Aeronautics Safety Code. For the complete Safety 
Code refer to 

Model Aviation

 magazine, the AMA web site or 

the Code that came with your AMA license.

General

1) I will not fl y my model aircraft in sanctioned events, air shows, 

or model fl ying demonstrations until it has been proven to be 
airworthy by having been previously, successfully fl ight tested.

2) I will not fl y 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 and avoid fl ying in the 
proximity of full-scale aircraft. Where necessary, an observer 
shall be utilized to supervise fl ying to avoid having models fl y 
in the proximity of full-scale aircraft.

3) Where established, I will abide by the safety rules for the 
fl ying site I use, and I will not willfully and deliberately fl y my 
models in a careless, reckless and/or dangerous manner.

5) I will not fl y my model unless it is identifi ed with my name 
and address or AMA number, on or in the model. Note: This 
does not apply to models while being fl own indoors.

7) I will not operate models with pyrotechnics (any device that 

explodes, burns, or propels a projectile of any kind).

Radio Control

1) I will have completed a successful radio equipment ground 

check before the fi rst fl ight of a new or repaired model.

2) I will not fl y my model aircraft in the presence of spectators 
until I become a qualified flier, unless assisted by an 
experienced helper.

3) At all fl ying sites a straight or curved line(s) must be 
established in front of which all fl ying takes place with the 
other side for spectators. Only personnel involved with fl ying 
the aircraft are allowed at or in the front of the fl ight line. 
Intentional fl ying behind the fl ight 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 fl ying 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 fl ight; 

nor should any part of the model 

other than the landing gear, intentionally touch the ground, 
except while landing.

CHECK LIST

Perform these last-minute checks to make sure nothing has 

been forgotten:

 

 1.   Confi rm that all controls respond in the correct direction 

and the throws are set up according to the manual. 

 

 2.   Make sure you have checked the C.G. as instructed.

 

 3.   Make sure the lock nuts are present on all the screws 

that retain the pushrods to the servo arms and that 
the screws that retain the servo arms are in place.

 

 4.   Be certain the battery and receiver are securely 

mounted. 

 

 5.   If using a radio system on 72 MHz, be certain to extend 

the receiver antenna all the way down the antenna 
tube in the fuselage.

 

 6.   Use threadlocking compound to secure all critical 

fasteners including any servo screws that go into a 
metal output shaft.

 

 7.   Add a drop of oil to the axles so the wheels will turn 

freely.

 

 8.   Make sure all hinges are securely glued in place.

 

 9.   Reinforce holes for wood screws with thin CA where 

appropriate.

 

 10.   Where appropriate, secure connections between servo 

wires and Y-connectors or servo extensions, and the 
connection between your battery pack and the on/off 
switch with vinyl tape, heat shrink tubing or special 
clips suitable for that purpose.

 

 11.   Make sure the fuel lines are connected and are not 

kinked.

 

 12.   Balance the propellers (and spare propellers).

 

 13.   Place your name, address, AMA number and telephone 

number on or inside your model.

 

 14.   Cycle your receiver battery pack (if necessary) and 

make sure it is fully charged.

 

 15.   Range check your radio when you get to the fl ying 

fi eld.
