4. Slide the stabs onto the aluminum tubes witht he stab
root ribs tight on the fuse side.
❏
5. Drill a 1/16" [1.6mm] hole through the forward and aft
stab tubes, using the holes in the bottom of the stab half as
a guide. Be careful not to drill through the stab.
❏
6. Attach the stab half to the tubes with two #4 x 5/8"
[15.9mm] screws and two #4 washers.
❏
7. Have an assistant hold the stab halves tight against
the fuse. Drill the tubes for the second stab half.
❏
8. Attach the second stab half to the tubes with two #4 x
5/8" screws and two #4 washers.
❏
9. Attach 36" [915mm] servo extensions to the rudder
servos. Route the extensions to the radio compartment.
❏
10. Install the rudder servo hatch with two #4 x 5/8"
[16mm] screws.
❏
1. Wrap your receiver and battery in 1/2" [13mm] foam.
Mount your receiver and battery to the servo tray with the
Velcro strips.
❏
2. Plug in all of the servos, including the two 6" [150mm]
extensions for the ailerons.
❏
3. Mount the switch and charge jack.
There are two wing locations on the plane. The reason
for this is so that a range of engines can be used without
the need for adding large amounts of weight to balance.
❏
1. First, determine which wing mounting location you will
use. To do so, mount everything in the plane except the
canopy and wing. Reach under the tank and lift the plane by
the aft wing tube. If the plane is balanced, tail-heavy, or just
slightly nose-heavy at this location, then this is where the
wing will be mounted. If the plane is significantly nose-heavy,
set it down and lift it by the forward wing tube. If the plane is
more closely balanced, or still nose-heavy, using the forward
tube, then this will be your wing location. If the plane is now
tail-heavy using the forward wing tube to lift, use some
weight strips to balance the plane in each location. Mount
the wing in the position which requires the least weight.
❏
2. Cut the covering from the wing tube locations you
selected in step 1.
❏
3. Slide the wing tube through the fuse.
❏
1. Slide one wing onto the wing tube. Remove the
covering from the appropriate holes in the fuselage for the
wing dowels.
❏
2. Attach the wing to the fuselage with the 1/4"20 x 2"
[50mm] nylon bolt.
❏
3. Attach the second wing to the fuselage.
