Hangar 9 Funtana 125 ARF Assembly Manual

 

Step 22

Gently pull on the rudder and fuselage to make sure each of 

the hinges is secure. If not, reapply CA to the hinge that is 

not secure.

 

Step 23

Flex the rudder through its range of motion a few dozen 

times to break in the hinges.

 

Step 24

Use a felt-tipped pen to mark the locations for the two 

screws that will secure the tail wheel bracket to the fuselage.

 

Step 25

Move the bracket out of the way and use a drill with a 1/16-

inch (1.5mm) drill bit to drill the two holes for the screws.

 

Step 26

Place 2–3 drops of thin CA into each hole to harden the 

surrounding wood. This will keep the screws from pulling 

out of the fuselage.
