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

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 (that’s why it’s 
called a 

check list!

).

 

❏ 

1.  Check the C.G. according to the measurements 

provided in the manual.

 

❏ 

2.  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.

 

❏ 

3.  Extend your receiver antenna (if applicable).

 

❏ 

4.  Balance your model 

laterally

 as explained in the 

instructions.

 

❏ 

5.   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.

 

❏ 

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

freely.

 

❏ 

7.  Make sure all hinges are 

securely

 glued in place.

 

❏ 

8.  Reinforce holes for wood screws with thin CA where 

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

 

❏ 

9.  Confi rm that all controls operate in the correct direction 

and the throws are set up according to the manual.

 

❏ 

10.  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.

 

❏ 

11.  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.

 

❏ 

12.  Make sure any servo extension cords you may have 

used do not interfere with other systems (servo arms, 
pushrods, etc.).

 

❏ 

13.  Secure the pressure tap (if used) to the muffl er with 

high temp RTV silicone, thread locking compound or 

J.B. Weld.

 

❏ 

14.  Make sure the fuel lines are connected and are 

not kinked.

 

❏ 

15.  Balance your propeller (and spare propellers).

 

❏ 

16.  Tighten the propeller nut and spinner.

 

❏ 

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

number on or inside your model.

 

❏ 

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

make sure it is fully charged.

 

❏ 

19.  If you wish to photograph your model, do so before 

your fi rst fl ight.

 

❏ 

20.  Range check your radio when you get to the 

flying field.

FLYING

The Dirty Birdy ARF is a great-fl ying model that fl ies smoothly 

and predictably. The Dirty Birdy does not, however, possess 
the self-recovery characteristics of a primary R/C trainer and 
should be fl own only by experienced R/C pilots.
