Locate the threaded aileron pushrods, 2 ball links, 2 screws, 2 nuts and 2 washers 
that make up the aileron linkage.

We highly recommend the use of the Dubro heavy duty control arm set for the 
Extra, Dubro part number 670 for Futaba, 671 for JR, and 672 for Hitec.  For the 
aileron linkage we will use the 1.14” (28.9mm) arm.  Electronically center the 
servo arm.  Thread the ball links onto each end of the pushrod.  Attach the 
pushrod to the servo arm and control horn using the supplied screws, nuts and 
washers as shown in the photo.

Repeat this process for the other wing and the wings are finished and ready for 
flight! 

 

Fuselage Assembly

 Let’s mount the landing gear first.  Locate the 2 carbon fiber landing gear legs, 4 
3mm mounting bolts and washers, 2 main wheels, 2 axles and retaining nuts, 2 
wheel collars, 2 wheel pants, 2 landing gear fairings and the 2 plywood mounting 
plates.
