achieve proper balance.
For the front servo
installation, skip to step 64,
for the rear servo
installation, continue to next step.
61. Locate the holes in the side of the fuse for the tail
servos. There is one on each side. Note that the
cutouts are not opposite each other, but are
offset. This allows you to mount one servo with
the arm down and the other with the arm up,
eliminating the need for a servo reverser and
allowing you to use a standard “Y” harness. Cut
the covering from the slots with a sharp hobby
knife.
62. Locate the two push rods, (2) 8” 2-56 rods.
Install a clevis on the end of each 2-56 rod, then
install a 4 arm servo horn on each servo, making
sure the arms are square to the tail surfaces.
63. Plug a clevis into each coupler and rod, then lay
them across the servo arm. Mark the location of
the servo arm holes on the control rods. This is
the location for the “z” bend on the each control
rod. Make a “z” bend on each control rod with
needle nose pliers or “z” bend pliers, then cut off
the excess control rod. Install the “z” bend on
the servo arm, at the same hole on each arm.
You may need to enlarge the hole with a small
drill bit. Cut off the (3) extra arms with wire
cutters.
Skip to step 77.
64.
Front servo installation.
Note: For 3d
aerobatics or when using a high-end motor,
use the rear servo method and use 4-40
pushrods, even if nose weight is needed for
proper balancing.
You will need the following
materials, a 24” x 3/8 Dia. Hardwood dowel
(NI), (2) 2-56 x 12” control rod (dubro #172), (2)
2-56 clevis (Dubro#122), and (2) pieces of 3/8
shrink tube (Dubro #440) or thread and CA to
fasten the ends of the control rod.
65. Twist the 2-56 clevis on the end of each push
rod, then measure back 6”. Make a bend of
about 5 degrees at that distance.
66. Measure 1-1/4” in on each end of the pushrod.
67. Use a sharp hobby blade to cut one groove on the
servo end, and two groves on the elevator end of
the push rod. Make sure the servo end is
centered from the two grove end.
68. Drill a 3/32” hole at the back of the groove,
through the pushrod. Make a second hole on the
two groove end, about 1/8 forward of the first.
69. If you are using shrink tubing, slide it on the
pushrod now. If you are using thread and ca,
continue on.
70. Align the control rods on the elevator end of the
pushrod, keeping the clevis even with each other.
Mark the control rods where they intersect with
