NOVAK XXL FM RECEIVER Operation Manual

RECEIVER OPERATION MANUAL
THE NOVAK XXL RECEIVER
The Novak XXL is an extra-small, extra-light two
channel receiver with ultra-narrow band 10 kHz
channel spacing. The XXL is extra-big on performance
with outstanding range, superior noise rejection,
low voltage operation down to 3.0 volts DC, and
solid state reverse voltage protection. When inserted,
the crystal is fully enclosed within the receiver's case
and extra plastic crystal holders are included. The
XXL receiver works with all popular radio systems
and accepts Futaba, JR, Sanwa, Hitec, new KO, and
AirZ connectors, and accepts all DSC connections.

STEP 1
The XXL receiver has been factory tuned and requires
no further tuning.
1. Only use single conversion crystals.
2. The receiver's frequency is indicated by the color of the
antenna wire. The different frequencies are marked
on the receiver's case label.
3. On 75 MHz it is
XXL receiver made for your brand of transmitter. The
XXL uses an ultra-narrow band
for 10 kHz channel spacing. Using it with a different
radio brand will result in less than optimum performance.
The frequency tolerance of all crystals other than 75
MHz are close enough that 27, 29, and 40 MHz XXL
receivers are not brand specific.
4. Transmitter and receiver crystals MUST be made by
the transmitter maker and be on the same modulation,
band, and frequency
transmitter crystal must be used with Futaba FM/75 MHz/Ch.90
receiver crystal)
5. Crystals are sensitive to vibration and should not be
dropped.
6. Carefully insert the receiver crystal into the receiver
by guiding the two prongs into the receiver's crystal
socket holes. Most crystal plastics will fit into the XXL
receiver, so it is not necessary to remove the crystal's
plastic housing if it was supplied with one. Spare plastic
crystal holders are also included in case your crystal
does not have one.
be inserted in either direction.
Always use FM crystals in FM receivers & AM crystals in AM receivers
STEP 2
The XXL receiver will accept Futaba, JR, Hitec, and new-
style Sanwa & KO input plugs. JR style plug plastics are
included to change over other styles. The next two
(3.28x2.82x1.35cm)
sections describe how to change the plug plastics and
(13.61 grams)
wiring for the type of radio system you have.
Futaba style connectors will fit into the XXL without
modification or wiring sequence change.
JR, Hitec, new-style KO, and Airtronics Z connectors
will fit into the XXL without modification or wiring
sequence change. However, you MUST be sure that the

brown wire on the JR, and the black wire on the
(45.72 cm) Hitec, new KO, and AirZ harnesses are closest to the
outside/left edge of the case.
RADIO CYRSTAL SELECTION, CARE, & INSTALLATION
Crystals are not included with the receiver.
VERY IMPORTANT that you use the
ceramic filter

(Example: Futaba FM/75 MHz/Ch.90
. Receiver crystals are usually marked "RX".
A hard crash can damage receiver crystals.
Crystals are non-polarized and can

STEP 2
INPUT PLUGS (Sanwa/Airtronics & old KO)
This section describes how to change old-style KO
and Sanwa/Airtronics connectors to the JR style.
1. With a small standard screwdriver, press on each of the
three metal locking tabs on the sockets until the wires
are easy to remove. Remove wires.
2. With the screwdriver, carefully lift each of the metal
locking tabs to the angle shown.
3. Sockets should "click" into place. The locking tab must
not extend outside plug housing.
4. Old-style KO harness––Insert black wire into BLK plug
slot. Insert red wire into the center plug slot. Insert
blue wire into the WHT plug slot.

5. Old-style Sanwa/Airtronics harness––Insert middle
black wire into the BLK plug slot. Insert outside black
wire into the WHT plug slot. Insert red wire into the
center plug slot.

Improper wiring sequence may damage receiver, servo, and ESC.
STEP 3
MOUNTING INSTRUCTIONS
This section describes how to properly mount the
receiver and avoid damage due to vibration or shock.
1. Electric Cars & Boats––Mount the XXL with the
included double-sided tape as close to the antenna
as possible, where the receiver's case will not contact
the chassis or other rigid surfaces.
2. Gas Cars & Boats––The XXL should be mounted
in foam rubber and protected from fuel and water.
Do not use glue to mount the receiver!
3. Tubular Plastic Antennas––Run the antenna wire
up through the plastic antenna tube and let the
excess wire trail out the top of the tube.
4. Rigid Antennas––Wrap antenna wire around the
mast with 1/4" spacing. Shrink wrap or tape the top
to secure the wire and let the excess trail off the top.
Do not cut or coil excess wire––Range will be reduced!
