Locate the control horns in the provided kit. You will find three longer horns 

and one shorter one. Two long ones will be used for the ailerons and one long 

horn for the rudder. The shorter one will be used on the elevator. You will 

notice a cutout on the bottom of the elevator horn that will fit over the 

elevator spar.  

 

Shown above is one of the aileron horns in place on the top of the aileron.
