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 qualifi ed fl ier, 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

During the last few moments of preparation your mind may 
be elsewhere anticipating the excitement of the fi rst fl ight. 
Because of this, you may be more likely to overlook certain 
checks and procedures that should be performed before the 
model is fl own. To help avoid this, a check list is provided 
to make sure these important areas are not overlooked. 
Many are covered in the instruction manual, so where 
appropriate, refer to the manual for complete instructions. 
Be sure to check the items off as they are completed.

❏  

1. Fuelproof all areas exposed to fuel or exhaust residue 
such as the cowl mounting blocks, wing saddle area, etc.

❏  

2. Check the C.G. according to the measurements 
provided in the manual.

❏  

3. Be certain the battery and receiver are securely 
mounted in the fuse. Simply stuffi ng them into place with 
foam rubber is not suffi cient.

❏  

4. Extend your receiver antenna and make sure it has 
a strain relief inside the fuselage to keep tension off the 
solder joint inside the receiver.

❏  

5. Balance your model 

laterally

 as explained in the 

instructions.

❏  

6. Use threadlocking compound to secure critical 
fasteners such as the set screws that hold the wheel 
axles to the struts, screws that hold the carburetor arm (if 
applicable), screw-lock pushrod connectors, etc.

❏  

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 (servo mounting screws, cowl mounting 
screws, etc.).

❏  

10. Confi rm that all controls operate in the correct direction 
and the throws are set up according to the manual.

❏  

11. Make sure there are silicone retainers on all the 
clevises and that all servo arms are secured to the 
servos with the screws included with your radio.

❏  

12. 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.

❏  

13. Make sure any servo extension cords you may have 
used do not interfere with other systems (servo arms, 
pushrods, etc.).

❏  

14. Secure the pressure tap (if used) to the muffl er with high 
temp RTV silicone, thread locking compound or J.B. Weld.

❏  

15. Make sure the fuel lines are connected and are not 
kinked.

❏  

16. Balance your propeller (and spare propellers).

❏  

17. Tighten the propeller nut and spinner.

❏  

18. Place your name, address, AMA number and 
telephone number on or inside your model.

❏  

19. Cycle your receiver battery pack (if necessary) and 
make sure it is fully charged.

❏  

20. If you wish to photograph your model, do so before 
your fi rst fl ight.

❏  

21. Range check your radio when you get to the fl ying fi eld.
