o 

17 . Locate your rudder servo and servo arm that you set 

aside  earlier .  If  you  didn’t  do  so  already,  center  the  servo 
and remove the arm . Set the servo in the servo bay with the 
output shaft facing aft as shown . Fit the servo arm so that 
you choose the arm that is 90° to the 

pushrod . Use a #48 

drill bit to drill the outermost hole of the servo arm . Cut off the 
unused servo arms .

o 

18 . Hold the servo in position so that the rudder pushrod 

is directly in line with the outermost hole of the servo arm 
or  about  5/8"  [16mm]  from  the  center  of  the  servo  output 
shaft . Drill four mounting holes using a 1/16" [1 .6mm] drill bit . 
Install the servo using the screws provided with your servo . 
Remove the servo and harden the holes with thin CA .

o 

19 . Set the rudder at neutral . Mark the rudder pushrod 

at the servo arm and bend the rod straight up 90° . Attach 
the pushrod to the servo arm using a nylon FasLink . Secure 
the  servo  arm  using  the  attachment  screw  provided  with 
your servo .

o 

20 .  With  your  rudder  servo  still  centered,  adjust  the 

rudder  clevis  so  that  the  rudder  is  at  neutral  throw . When 
you’re satisfied, slide the silicone retainers into position over 
the clevises for the rudder, elevator, ailerons, and throttle .

GLOW ENGINE INSTALLATION

This  section  describes  how  to  install  an  O .S .  FL-70  four-
stroke glow engine . Two and four-stroke engine installations 
are  similar  with  the  exception  of  throttle  pushrod  location . 
If  you  choose  to  use  a  two-stroke  engine,  we  recommend 
using  either  the  O .S .   .46  AX  or  the  O .S .   .55  AX .  When 
installing  an  engine  other  than  the  ones  recommended, 
choose the throttle pushrod hole in the firewall that best suits 
your application .
