OWNER’S MANUAL
INTRODUCTION:
Thank you for purchasing the FMA Direct Fury FM surface receiver. Designed in
collaboration with Sergio Zigras of Z-Tron, this tiny new surface receiver packs a so-
phisticated microcontroller and advanced dual conversion circuitry into a package with
the footprint of two postage stamps side by side. With dimensions of
1.82"x0.94"x0.67" and a weight of a mere 0.6 oz (18 gm) encased, the new Fury will re-
define the term performance in the surface market. Built on the foundations of reliable
aircraft model receiver technology only found in FMA Direct receiver products, the new
Fury will provide glitch free operation in even the most severe racing and boating con-
ditions. Because it is microprocessor based, Fury includes new advanced S.M.A.R.T.
(Selective Microprocessor Advanced Radio Transmission) decoding that digitally filters
every frame of information to ensure that the servos never react to any random noise
that might get past the superior RF circuitry. In the unlikely event that RF noise does
get too high for reliable control, the Fury will failsafe to a “no servo output” state. This
is great if you have an electric car and somebody turns a transmitter on your fre-
quency. The ESC will automatically go to zero throttle. Available in two basic models
to accommodate FM shift, the Fury supports either positive or negative FM modula-
tion. Heavy-duty, SMT construction on a single, glass-epoxy P.C. board along with
various other circuit improvements make the Fury design one of the most reliable we
have ever produced. So plug it in and FEEL THE FURY!

PREPARATION:
•TRANSMITTER COMPATIBILITY, POWER AND SERVO CONNECTION
Fury receivers are available in two models to
support both positive and negative modulation
(Futaba/Hitec or JR/Airtronics). TABLE 1 high-
lights transmitter compatibility depending on the
part number and what is listed on your receiver
label. If you are unsure which model receiver you
have, contact FMA Direct immediately. Fury
receivers are designed for use with all standard
servo/ESC connectors and support Futaba, JR,
Hitec servos, and Airtronics servos equipped with
the new “Z TYPE” connectors, as well as other
brands that use standard polarity (GROUND,
PLUS, SIGNAL). When connecting power,
ESC’s, and servos to your Fury, please refer to
TABLE 2 and Figure 1 for proper hookup of your
equipment. Note: with the receiver sitting label
side up, the ground (negative) lead (marked #1 in
Figure 1 and color coded as in TABLE 2) must
match up to the pin closest to the outside edge of
the receiver. No damage will occur by plugging a
servo or ESC in backwards, but the device will
not operate. You may mix and match any stan-
dard type servos and ESC’s, but neither may be
used in combination with “Old Style” Airtronics
equipment – see warning below. When hooking
up power to your receiver, you may either con-
nect a NiCd battery pack to any unused channel
input or use a “Y” harness to connect the battery
and a servo simultaneously to any receiver chan-
nel. In electric car and boat applications, the
ESC will provide power to the receiver on the
throttle output channel. This is usually either channel 3 or 4 of the receiver depending on the
brand of transmitter being used. The throttle output channel from the receiver may not nec-
essarily be the same as your existing receiver. Just plug the ESC in to the various receiver
channel output until you find the one that works. The same is true for steering channels, etc.
Just remember, for every transmitter channel being sent to the receiver, there is only one
corresponding output channel on the receiver.
WARNING: IF YOU INTEND TO INTERFACE AIRTRONICS SERVOS OR ESC’S THAT
USE “OLD STYLE” (PRE-“Z TYPE”) AIRTRONICS CONNECTORS TO THE FURY, YOU
MUST UPDATE THE CONNECTOR TO THE CURRENT INDUSTRY STANDARD
POLARITY (SEE FIGURE 1) AND PROPER INDUSTRY STANDARD SHELL THICKNESS.

YOU MAY READILY CONVERT YOUR EXISTING “OLD STYLE” AIRTRONICS
CONNECTORS TO CURRENT STANDARDS 1) BY INSTALLING APPROPRIATE
ADAPTERS (FMA PN 217AJ) OR 2) BY REMOVING THE OLD CONNECTORS AND PINS
AND REPLACING THEM WITH FMA PART NUMBER SEASSYJ. EACH SEASSYJ
CONTAINS ONE JR COMPATIBLE MALE SHELL AND 3 FEMALE PINS. YOU WILL
NEED TO CRIMP THE PINS AND SOLDER THEM TO THE WIRES OF YOUR EXISTING
SERVO/ESC AND PLUG THEM INTO THE SHELL PROVIDED. MAKE CERTAIN THAT
THE RED WIRE (+V) GOES TO THE CENTER PIN AS ILLUSTRATED IN FIGURE 1. FMA
WILL NOT ACCEPT RESPONSIBILITY FOR ANY ATTEMPT TO USE “OLD STYLE”
AIRTRONICS CONNECTORS WITH FURY RECEIVERS THAT DO NOT HAVE THE
POLARITY CHANGED TO INDUSTRY STANDARDS.
•CRYSTALS
All Fury receivers support full crystal interchangability using FMA Direct Quantum or Fortress
series dual conversion 75 MHz crystals. The only difference between these crystals is the
size. The new Quantum series crystals are low-profile and will not protrude beyond the re-
ceiver case top. Contact your local FMA Direct dealer or call FMA Direct to obtain the
correct crystal for operation with your transmitter frequency. Slide the crystal through the
opening in the case top and plug the crystal into the gold-plated crystal sockets mounted on
the printed circuit board.
INSTALLATION
Care must be taken when installing your receiver to isolate the electronics from vibration. When
possible, do this by wrapping the receiver in 3/8” thick foam rubber. Restrain the foam-packed
receiver using Velcro or a rubber band if necessary. If you are unable to fit foam around the re-
ceiver in your installation, use shock absorbing adhesive foam instead. NOTE: FAILURE TO USE
FOAM RUBBER OR FOAM TAPE AS DESCRIBED ABOVE DURING INSTALLATION VOIDS
PRODUCT WARRANTY. Extend the antenna to its full length. Do not coil the antenna up or range
will be shortened. If you are installing the Fury in a small vehicle and you require a shorter antenna,
you may cut off a portion of the 39.75” antenna without de-tuning the receiver; a unique feature of
FMA Direct receivers. Reducing antenna length will reduce range, however. Proceed carefully,
removing only a short amount at a time and be certain to ground range check the receiver with each
incremental reduction in antenna length. Try not to cut the antenna shorter than 18” whenever pos-
sible. When hooking up servos and ESC’s to your receiver, use TABLE 1 and FIGURE 1 to check
their plug wire color orientation.
RANGE TEST
To assure proper performance, the Fury receiver must be range tested with the "host" transmitter.
The major reason for this important test is that over time, all R/C transmitters are susceptible to de-
tuning and frequency “drift”. To ensure the utmost in secure RF reception, current technologies for
narrow-banding used in FMA designs can actually place a higher demand on transmitters. Power
level and frequency accuracy of your transmitter are more important than ever before. Therefore,
for the initial range check and in rare cases when you suspect degradation of performance from
your R/C system, FMA would like to suggest the following guidelines: Do not install a switch
harness for the initial range test because switch harnesses are often the cause of poor range. The
power switch on an ESC installation is O.K. Collapse your transmitter antenna. With the receiver
mounted in the vehicle, apply power and walk away from the receiver moving one control on the
transmitter. You should obtain at least 100 feet of line-of-sight ground range if everything is
operating properly. If any loss of servo control occurs, the system might need to be calibrated by an
FMA service station. CALL [phone] for FMA Direct technical assistance. In certain cases,
the FMA service station may ask you to send in your transmitter along with your receiver.
ACCESSORIES:
Y-harness, switch harness, and numerous other accessories as well as a full line of servos,
batteries, and chargers are available for use with your FMA receiver either direct or from your local
FMA dealer.
