E-flite Brio 10 ARF - Manual (Page 45)

Note: An optional rudder servo location has
been provided at the rear of the fuselage if
using heavier motors and you choose not to use
the pull-pull system. The installation procedure
is identical to the elevator servo installation,
except the covering must be removed from the
fuselage first.
At this time, we suggest that you trial fit the
battery and receiver into the front of the
fuselage and follow the steps outlined on page
49 and check the CG location. If it is nose
heavy, you might consider installing the servo
at the optional rear location. If you do not
anticipate an issue, than proceed with Step 4
and install the rudder servo in the fuse for a
pull-pull system.
Note: Steps 4 through 10 illustrate the
installation of the pull-pull system. When
using the pull-pull system, continue on starting
at Step 6.
