Use the longer, heavy duty double ended stock servo arm that comes with the HS-55 (or
the cross shaped horn on the new HS-56 servo.)
Use these heavy duty arms only as any
other arms are too fragile.
Mount the pushrod screw to the OUTER hole ( farthest from
center) for maximum pushrod travel or the middle hole for less travel but more holding power.
As briefly stated above, once the servo arms are prepared you will need to turn on your radio
so the servos center before you attach the arms or wheels to their output shafts. To turn the
radio on, plug the speed control connector into the battery pack and if your controller has an
on/off switch, turn it on.. The speed control radio receiver lead must be plugged into the
THROTTLE CHANNEL
slot on the receiver. Set trim tabs on your transmitter to neutral and slip
the tail servo arm onto the servo shaft and secure with supplied screw. Make sure the servo
arm screw is tight because this will be holding the tail onto the bird. The tail should set on the
servo as straight as possible with the trim tabs centered. When viewed from the rear of the
model, a left turn command should rock the tail to the left and vise versa.
Set the servo travel
to 150% if your radio allows this as you will need this extra servo travel to turn tightly
sometimes.
The elevator servo set up is slightly different. Set the elevator trim tab to neutral and pull the
elevator stick on the transmitter all the way back in the "up" position. Rock the tail as far as it
will go forward and then slip the servo arm onto the elevator servo shaft with the tail in this
position with the transmitter stick being held back the whole time.
Please note that the
elevator servo arm mounts in a vertical position onto the elevator servo and the pushrod
attaches to the top of the arm, not the bottom.
This will set the maximum tail pitch deflection
at the full up transmitter stick setting but still allow some "up" trim to be added when the stick is
at neutral. This "up" trim will be used when hand launching the Slow Hawk.
The neutral pitch angle of the tail should be about 20-25 degrees from the horizontal.
IMPORTANT
: We must emphasize that the recommended servos for this model are the above
mentioned
Hitec HS-56 or optional HS-55.
These servos are not only known to be suitable for
their size, weight, speed, and torque, but also because they have strong output arms or discs
that can withdtand the flight loads. Other brands may not and can cause a crash!
Please use the recommended Hitec brand servos only.

11) Installing the Wing:
Lay the wing out flat on a large table. One side of the wing has dacron sleevs running down it.
This is usually considered the top of the wing but in reality the wing is reversible and either side
up will fly equally as well.
Unbundle the spars. The main spars have an aluminum ferrule attached to them. The
diagonal spars are thinner and have a plastic ball housings attached to them.
Slip the main spars into the dacron sleeves in the leading edge of the wingsail.
Slide the spars in the sleeves running down the wingsail.
Slip the bare carbon end first into the sleeve. The plastic ball housing will protrude out the
back and center of the wing and will snap onto the metal balls mounted at the root of the
fuselage.
