The low parts count and well-fitting parts

is the next
step in the
spar goes in first,
and the two stabilizer halves simply slide
in over it. The root of each stabilizer half
fits snugly in a hard, plastic fillet and
they key into each other for the moving
elevator surface. Two short screws—one
on each half—anchor the horizontal
stabilizer into the fillet. Attaching the
clevis to the recommended outer hole
of the elevator control horn finishes the
tail section. All other clevises are factory
installed and attached.
Moving on to the wing, the Y
connectors needed for the aileron, flaps,
and landing gear are included in a parts
bag. Plugging in the Y connectors to
their prelabeled servo leads while noting
correct polarity is easier with the wing
apart from the fuselage.
Feeding the wires up through the
fuselage and toward the receiver is next.
is down and fitting snugly with no servo
leads pinched, it is time
to secure the wing with the four long
After the wing is attached, plug
the servo leads into their prospective
channels on the AR636A Spektrum
receiver. The ailerons must be plugged
into the Aileron #2 channel for the
AS3X to properly work. Now you can
check the control surface directions.
With the propeller still off of the
airplane, throttle up to 25% and then
lower the throttle to engage the AS3X
stabilization system to test it. You can
reference the table in the manual to
ensure everything is correct. I have flown
many AS3X-equipped aircraft and they
were always spot on out of the box, but
it is important to check.
The propeller installation is the next
step illustrated in the manual, but I
think that binding the airplane with the
propeller off of the model is best to do
next. Plus, you can extend the scalelike
landing gear and get the aircraft sitting
on its gear to finish the assembly.
As I mentioned earlier, setting up
the transmitter is one of the first steps.
Setting failsafe by rebinding the aircraft
after the initial setup is always a good
idea. You might find that after binding
the receiver with the manual settings,
your flaps are not at a perfect neutral
Simply return to the Flap System
screen on your transmitter and adjust
the numerical values to give you the
desired flap position. The values might
differ slightly from the manual callouts.
At this point, rebinding to set the
failsafe is a good idea. It ensures that the
receiver remembers the proper neutral
settings in case of a signal loss.
I’m using a DX6, which allows me to
set the flap deployment as a two-second
operation. Voice alerts add a cool factor
as well. It’s pretty neat to have the radio
tell me things such as gear down, flaps
up, and time expired.
Now that the system setup is
complete, installing the propeller
assembly is the next order of business.
The spinner backplate goes on first. It
fits nicely on the base of the preinstalled
propeller shaft, followed by the one-piece four-blade propeller, then the
barrel nut. The round barrel nut can be
tightened with a small screwdriver. The
