❏ 

12. Test fi t the rudder to the fuselage by inserting the 

other sides of the hinges into their mating slots and the nylon 

tab on the tail wheel wire into the larger slot at the bottom of 

the fuse. If necessary, use a hobby knife to enlarge the hinge 

slots to more easily accept the hinges.

❏ 

13. When satisfi ed with the fi t, remove the rudder from 

the fuse and remove the tail wheel wire from the rudder. Mix 

up a small batch of epoxy and apply a light coating to the 

end of the tail wheel wire that fi ts into the rudder and also 

to both sides of the nylon tab. Reinstall the rudder onto the 

fuse (using the CA hinges) taking care to wipe away any 

excess epoxy with alcohol. Remove the pins from the hinges 

and position the rudder against the TE of the fi n. The hinge 

gap between the rudder and fi n should only be wide enough 

to allow a small line of light through. When satisfi ed, apply 

6 drops of thin CA glue to the center of each hinge on both 

sides (the hinges will hold the rudder in place while the 

epoxy on the tail wheel wire and tab hardens). When the 

CA has dried, gently pull on the rudder to confi rm that it is 

securely glued in place.

INSTALL THE TAIL PUSHRODS

AND SERVOS

❏ 

1. Thread a nylon clevis onto each of the 27" [686mm] 

pushrods along with silicone clevis retainers. Attach the 

clevis of one pushrod to the outer hole of a large control horn. 

Insert the pushrod into the elevator pushrod exit slot. Use 

the pushrod to position the control horn onto the underside 

of the right elevator half with the holes aligned over the hinge 

line and mark the location of the control horn mounting holes. 

Drill 5/64" [2mm] holes at your marks and install the control 

horn using two 2-56 x 1/2" [13mm] screws and a control 

horn backplate.

❏ 

2. Trim the bottom corner from the rudder control horn 

(small control horn). Install the control horn onto the left side 

of the rudder using two 2-56 x 1/2" [13mm] machine screws 

in the same manner as you did with the elevators.
