RECEIVER OPERATION MANUAL

THE NOVAK XXTRA RECEIVER

Novak introduces the world’s first small size, light weight,

low power synthesized receiver for R/C cars and boats.

Forget those extra receiver crystals, now selecting the

frequency channel is as easy as rotating two switches.

Based on the rock-solid XXL circuitry, the XXtra adds a

crystal-controlled phase locked loop oscillator, and five

output channels for the ability to control extra servos.

With outstanding range, superior

noise rejection, low

voltage operation (down to 3.0 volts DC), and solid state

reverse voltage protection, the XXtra outperforms the

competition. The XXtra works with all popular radio

systems and DSC (Direct Servo Control) connections, and

accepts Futaba, JR, Sanwa, Hitec, & new KO connectors.

>+4 dBm

Voltage Range ...............................3.0 to 10.0 volts DC

Antenna Length .......................... 18 inches (45.72 cm)

Current Consumption .......

18.0 mA (over full voltage range)

The XXtra has been factory tuned and requires no further

tuning. This section describes how to select frequency channel.

1. Frequency band is marked in purple circle on case label.

To set the frequency channel to match your transmitter,

simply adjust the ten position rotary switches using a

#1 phillips or small

(1/8”) flat blade screwdriver, rotate

switches until they point to the proper channel numbers.

•The 75 MHz receiver has 2 number sets on the

1st DIGIT

switch. Top numbers are for Hitec & Futaba transmitters.

Bottom numbers are for JR, Sanwa/Airtronics, KO, & Multiplex

(MPX)

transmitters. The 2nd DIGIT switch has 10 positions.

To adjust a 75 MHz receiver to channel 76 (75.710 MHz)

for use with a Futaba transmitter, rotate the

1st DIGIT

rotary switch

to the ‘7’ position on the top, then rotate

the 2nd DIGIT switch to the ‘6’ position.

•The USA 27 MHz receiver has only 1 rotary switch. With

only 6 channels allowed on 27 MHz, there is no need

for the 1st DIGIT switch. To adjust this receiver rotate

the “2nd DIGIT” switch to desired frequency channel.

•All other receiver bands have two rotary switches, and

adjust by rotating the “1st DIGIT” switch to the first

number of the desired frequency channel, then rotating

the “2nd DIGIT” switch to the channel’s second number.

•EURO 40 MHz receiver channels are equal to the 3rd &

4th digits of the frequency. Adjust a 40 MHz receiver to

channel 67

(40.675 MHz) by rotating the

1st DIGIT

switch

to the ‘6’ position and

the 2nd DIGIT switch to the ‘7’.

Transmitter crystals MUST be made by the transmitter maker

and be on the same modulation and frequency band.

EXAMPLE: Futaba FM/75 MHz transmitter crystal must

be used with Futaba FM/75 MHz transmitter.

Transmitter crystals are usually marked “TX”.

STEP 1

RADIO FREQUENCY CHANNEL SELECTION

The XXtra receiver will accept Futaba, JR, Hitec, new-style

Sanwa/Airtronics (the blue color Z connector), and new-

style KO input

plugs. These two sections (Step 2 is broken

up into two different sections depending on which brand of

servo or speed control you have) describe how to connect

and/or change the plug plastics and wiring based on the

brand of radio system components you have.

• JR •

• Insert the plug plastic of the servo or ESC’s input harness

into the receiver with the BROWN wire toward the

outside/bottom edge of the case (marked NEG on label).

• Hitec • Futaba • New KO • Air Z •

• Insert the plug plastic of the servo or ESC’s input harness

into the receiver with the BLACK wire toward the

outside/bottom edge of the case (marked NEG on label).

STEP 2

INPUT PLUGS(Futaba, JR, Hitec, new KO/Sanwa/Air)

With some older ESC’s and servos, the sequence of the wires

in the plastic connector housing needs to be changed.

This is important, because the electronics inside the receiver

may be damaged if the wiring sequence is incorrect.

Changing the sequence is easy to do as described below.

• Old-Style KO •

•

Interchange the red and black wires in the KO plug

plastic of the input harness as shown in the figure below.

• Insert the input plug into the receiver with the BLACK

wire toward the outside/bottom edge of the case.

• Old-Style Sanwa/Airtronics •

• Interchange the middle black and red wires in the plug

plastic of the input harness as in the figure below.

• Trim the plug plastic* as needed to fit into the XXtra.

*Contact Novak to get JR style plug plastics if you do not want to trim.

• Insert the input plug into the receiver with the middle

BLACK wire toward the outside edge of the receiver.

With a small flat blade screwdriver, gently lift the plastic prong

until the wire and metal socket easily slides out of the plastic

housing. Repeat for each wire.

STEP 2

INPUT PLUGS (Sanwa/Airtronics & old KO)

The XXtra should be mounted so the receiver ‘floats’ to

avoid damage from vibration or shock, and position it

where the case will not contact other rigid surfaces.

DO NOT USE TIE WRAPS TO MOUNT RECEIVER!

1. Electric Cars & Boats––Mount XXtra with the included

double-sided tape as close to antenna mast as possible.

2. Gas Cars & Boats––Cut the included double-sided tape

in half and double-layer it for extra dampening.

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 of the mast.

Do not cut or coil excess wire––Range will be reduced!
