Checking the Wing W ashout
Required Parts
Wing
Required Tools and Adhesives
Heat gun
❍ 1. Place the wing on a flat surface and check the
wing washout. There must be 1/2" (13mm)
between the trailing edge of the wing at the tip
and work surface when the center of the wing
is flat against the work surface. If the wing is
not twisted correctly, hold the wing in a twisted
position and use a heat gun to remove the
wrinkles from the covering. Repeat the process
until the correct washout is present. The
washout makes the plane more stable in flight.
8
❍ 2. Secure the wing to the fuselage using a 4-40 x
1/2" socket head bolt and a #4 flat washer.
Note: The 4-40 socket head screw uses the
3/32" hex wrench.

of the stabilizer.
Note: The hole for the control horn will be on the
left side when the top is facing up.
9
❍ 2. Carefully remove the covering along the lines
using a sharp hobby knife. Be very careful not
to cut into the underlying wood and weaken
the stabilizer. If the stabilizer is weakened, it
could fail in flight.
❍ 3. Align a straight edge along the bottom of the
fin. Use a felt-tipped pen to draw a line onto
the lower front section of the fin. Draw lines on
both sides of the fin.
10
❍ 4. Remove the covering from the lower front
section of the fin 3/16" (5mm) below the
lines drawn in the last step. Also make sure
there is no covering on the bottom of the fin
as indicated. Leave the covering on the top
forward fin as shown.
❍ 5. Place the fin onto the top of the stabilizer.
The positioning of the fin will be as far back
in the notch as possible, aligned with the
covering removed from the stabilizer, and
square to the stabilizer. Use medium CA to
glue the fin to the stabilizer, keeping in mind
the three alignments.

the servo arms that are not in use, using side
cutters. Place the servos into the fuselage with
the connectors towards the outside of the
fuselage, and the servo arms towards the front
of the fuselage.
❍ 6. Use a 1/16" (1.5mm) drill bit to drill the
locations for the servo mounting screws.
16
❍ 7. Secure the ser vos using the screws provided
with your radio system.
❍ 8. Pass the ser vo leads through the opening in
front of the servos. Plug the ser vos into the
receiver, making sure the rudder and elevator
servos are in the correct channels. Plug the
speed control into the receiver at this time too.
17
❍ 9. Use two-sided tape to mount the receiver and
speed control to the sides of the fuselage.
❍ 10. Route the receiver antenna outside the
fuselage. Use tape to attach the antenna to the
tail. DO NOT cut the antenna, as this will
greatly reduce the radio range.

the opposite side of the fuselage from the
elevator control horn.
19
❍ 4. Make an L-bend in one of the pushrod wires
using small pliers.
❍ 5. Slide the pushrod wire into the pushrod tube
on the same side as the elevator control horn.
The wire will pass through the hole in the
micro control connector on the elevator servo.
❍ 6. Insert the L-bend in the pushrod through the
middle hole in the control horn.
20
❍ 7. Slide the micro pushrod keeper onto the L-
bend of the pushrod wire. The keeper then
snaps onto the pushrod wire, securing the wire
to the control horn.
❍ 8. Use a ruler to center the elevator in the neutral
position. With the radio system on, tighten the
screw in the micro control connector to secure
the pushrod wire at the servo.

Ruler
❍ 1. Turn on the transmitter and receiver of your
Gypsy. Check the movement of the rudder
using the transmitter. When the stick is moved
right, the rudder should also move right.
Reverse the direction of the servo at the
transmitter if necessary.
❍ 2. Check the movement of the elevator with the
radio system. Moving the elevator stick down
will make the airplane elevator move up.
29
❍ 3. Use a ruler to adjust the throw of the elevator
and rudder. Adjust the position of the pushrod
at the control horn to achieve the flowing
measurements when moving the sticks to their
endpoints. Moving the linkage at the control
horn can increase or decrease the throw.
Moving the linkage to the top of the horn will
decrease the throw, while moving toward the
bottom of the horn will increase the throw.
Elevator: 1/2" (13mm) Up 1/2" (13mm) Down
Rudder: 5/8" (16mm) Right 5/8" (16mm) Left
30
Center of Gravity
An important part of preparing the aircraft for
flight is properly balancing the model.
Caution: Do not inadvertently skip this step!
The recommended Center of Gravity (CG) location
for the Gypsy is 2
3
/8" (60mm) behind the leading
edge of the wing against the fuselage. If
necessary, move the battery pack towards the nose
or the tail until the correct balance is achieved.
31
Range Test Your Radio
❍
1. Before each flying session, be sure to range
check your radio. This is accomplished by
turning on your transmitter with the antenna
collapsed. Turn on the receiver in your
airplane. With your airplane on the ground
and the engine running, you should be able to
walk 30 paces (approximately 100 feet) away
from your airplane and still have complete
control of all functions.
If not, don’t attempt to fly! Have your radio
equipment checked out by the manufacturer.
❍ 2. Double-check that all controls (aileron,
elevator, rudder and throttle) move in
the correct direction.
❍ 3. Be sure that your batteries are fully charged,
per the instructions included with your radio.

2004 Official AMA
National Model Aircraft Safety Code
GENERAL
1) I will not fly my model aircraft in sanctioned events,
air shows or model flying demonstrations until it has
been proven to be airworthy by having been
previously, successfully flight tested.
2) I will not fly my model higher than approximately
400 feet within 3 miles of an airport without notifying
the airport operator. I will give right-of-way and avoid
flying in the proximity of full-scale aircraft. Where
necessary, an observer shall be utilized to supervise
flying to avoid having models fly in the proximity of
full-scale aircraft.
3) Where established, I will abide by the safety rules
for the flying site I use, and I will not willfully or
deliberately fly my models in a careless, reckless
and/or dangerous manner.
4) The maximum takeoff weight of a model is 55
pounds, except models flown under Experimental
Aircraft rules.
5) I will not fly my model unless it is identified with
my name and address or AMA number, on or in the
model. (This does not apply to models while being
flown indoors.)
6) I will not operate models with metal-bladed
propellers or with gaseous boosts, in which gases
other than air enter their internal combustion
engine(s); nor will I operate models with extremely
hazardous fuels such as those containing
tetranitromethane or hydrazine.
RADIO CONTROL
1) I will have completed a successful radio equipment
ground range check before the first flight of a new or
repaired model.
2) I will not fly my model aircraft in the presence of
spectators until I become a qualified flier, unless
assisted by an experienced helper.
34
3) At all flying sites a straight or curved line(s) must
be established in front of which all flying takes place
with the other side for spectators. Only personnel
involved with flying the aircraft are allowed at or in
the front of the flight line. Intentional flying behind the
flight line is prohibited.
4) I will operate my model using only radio control
frequencies currently allowed by the Federal
Communications Commission. (Only properly licensed
Amateurs are authorized to operate equipment on
Amateur Band frequencies.)
5) Flying sites separated by three miles or more are
considered safe from site-to site interference, even
when both sites use the same frequencies. Any
circumstances under three miles separation require a
frequency management arrangement, which may be
either an allocation of specific frequencies for each site
or testing to determine that freedom from interference
exists. Allocation plans or interference test reports shall
be signed by the parties involved and provided to
AMA Headquarters. Documents of agreement and
reports may exist between (1) two or more AMA
Chartered Clubs, (2) AMA clubs and individual AMA
members not associated with AMA Clubs, or (3) two or
more individual AMA members.
6) For Combat, distance between combat engagement
line and spectator line will be 500 feet per cubic inch
of engine displacement. (Example: .40 engine = 200
feet.); electric motors will be based on equivalent
combustion engine size. Additional safety requirements
will be per the RC Combat section of the current
Competition Regulations.
7) At air shows or model flying demonstrations, a
single straight line must be established, one side of
which is for flying, with the other side for spectators.
8) With the exception of events flown under AMA
Competition rules, after launch, except for pilots or
helpers being used, no powered model may be flown
closer than 25 feet to any person.
9) Under no circumstances may a pilot or other person
touch a powered model in flight.
