Centering the Control Surfaces

!

!

With  the  transmitter  turned  on  and  the  LiPo  flight  battery  connected  to  the  ESC  (and  installed  in  the  battery 
compartment)  it’s  now  possible  to  connect  the  pushrods  to  the  rudder  and  elevator  control  surfaces  and  to 
‘center’ the surfaces accordingly.

!

!

First, be sure to center the elevator and rudder (aileron) trim levers. See the ‘Transmitter Details’ and ‘Flight 
Controls and Trimming’ sections of this manual for more information on the trim levers and their functions.

 

!

With the trim levers centered, carefully spread open each ‘clevis’ (the white color plastic part installed on the 
threaded end of the metal pushrod) so you can insert the pin in the OUTERMOST hole on each control horn. It 
may  be  helpful  to  insert  a  flat  blade  screwdriver  (not  included)  into  the  clevis  then  carefully  ‘twist’  it  until  it 
disengages the pin from the hole in the clevis. Also, it is not necessary to ‘snap’ the clevis back together until 
the centering adjustments are complete.

!

!

After  connecting  the  clevises  to  the  control  horns  view  the  vertical  tail  and  rudder  from  directly  above.  The 
rudder should be ‘in line’ with the vertical tail when it’s properly ‘centered’. However, if the rudder is angled off 
to  the  right  or  left  you  can  adjust  the  length/position  of  the  pushrod/clevis  so  the  surface  is  centered 
‘mechanically’ while the trim lever on the transmitter is centered.
