INSTALL AILERON SERVO

1. Connect aileron with wing by five hinges each 
side. There are five slot on the wing and aileron. 
Half hinges insert in to wings and half to aileron.

2. Test fit the ailerons to the wing with the hinges. 
If the hinges does not remain centered. Stick a pin 
through the middle of the hinge to hold it in position.

3.Remove any pins you may have inserted into the 
hinges. Adjust the aileron so there is a small gap 
between the aileron and the wing. The gap should be 
small, just enough to see light through or to slip a 
piece of paper through.

4.Apply six drops of thin CA to the top and bottom 
of each hinge. Do not use CA accelerator. After the
 CA has fully hardened, test the hinges by pulling on
 the aileron.

5. Repeat this procedure for installing the right 
aileron.

Do the left  wing first so your work matches the 
photos the first time through. You can do one wing 
at a time, or work on them together.

1. Position a small nylon control horn on the aileron
positioning it as shown in the sketch and aligning it
with the servo. Mark the location fro the screw holes.
Drill through the marks you made with a drill bit. 
Mount the nylon control horn to the aileron by 
inserting three machine screws through the control 
horn and into the nylon mounting plate on the top
of the aileron.

2, Locate a pushrod wire threaded on one end .
Thread a nylon clevis onto the threaded end of 
the wire 20 turns. Install a silicone clevis retainer
onto the clevis. Then install the clevis on the 
aileron control horn.

3. Be sure the aileron servo is centered. Enlarge 
the hole in the servo arm with a Hobbico Servo 
Horn Drill. Center the aileron and align the wire
pushrod with the hole in the end of the servo arm.
Using a marker, mark the location where the wire
aligns with the hole in the servo arm on that mark
a 90 bend. From the bend measure an additional
9.5mm and the cut off the excess pushrod wire.

4.Install the wire into the hole in the servo arm 
using  a nylon FasLink as shown in the sketch.

P.2

1. The slot for servo installation is already laser cut
you just need to cut off the covering with knife.

2. Use four sheet metal screws to attach the servo to
the wing.

3.Pull the servo wire out the root of the wing.

4. Repeat this procedure for installing the right 
wing.
