fi tting the other end of the joiner tube into the other 
elevator. Press both halves fi rmly together to make sure

 3. Check that the screws in the screw-lock connectors 

are not tight so the pushrods can temporarily “fl oat” until 
the radio is set up later. 

  

 4. Fit the elevator and rudder pushrods into the 

middle

 

hole in their respective control horns and secure with the 

90° pushrod keepers

 5. Fit the 

tail gear wire

 into the tail gear assembly and 

secure with the M3 set screw lightly wetted with thread 
locker—a 1.5mm 

machined

 hex driver is preferred, but 

the included “L” wrench is suffi cient. Be certain the set 
screw locks onto the 

fl at spot

 in the wire. 

 6. Press the 

main landing gear wires

 all the way into 

the receptacles in the fuselage with the longer, “strut” 
portion of the wires toward the front as shown.
