GLOSSARY
It will be helpful to understand the following terms before reading the rest of the manual. The terms are not in alphabetical
order, but are in a logical order that prepares the reader for understanding the next term.
Reversing (servo reversing) -
hooking up the servos, a control on the model responds in the wrong direction, the user may change the servo's direction so
the control responds correctly.
Throw -
the distance the surface moves. Control surface throw is usually measured at the trailing
edge of the surface and is expressed in inches or millimeters. The model in the diagram has
1/2" [13mm] of up elevator throw. Throw can also refer to the distance a servo arm (or
wheel) travels.
Dual rate (D/R) -
between two different control throws for the aileron, elevator and rudder. Often, different
control throws are required for different types of flying. (

throws may be required for aggressive aerobatic maneuvers or landing or flying at lower
speeds where the model's response becomes less sensitive.)

Use this switch to “flip” between two aileron, elevator and rudder control throw settings. The throws can be set up however you
prefer, but generally, when the switch is “up” the throws are greater (“high rate”) and when the switch is “down” the throws are less
(“low rate”). This switch also flips between exponential rates (if used).

RADIO INSTALLATION
Follow these guidelines to properly mount the servos, receiver and battery.

wires. Always pull on the plastic connector instead.
• If any servo wires are not long enough to reach the receiver, servo extension wires (available separately) may be used.
• Always mount the servos with the supplied rubber grommets
screws. No part of the servo casing should contact the mounting rails, servo tray or any
other part of the airplane structure. Otherwise, vibration will be transmitted to the servo
causing premature wear and/or servo failure.

cut the receiver antenna or mount it in the model folded back on itself. Doing so will change its
electrical length, possibly reducing the distance from the pilot that the model can be controlled (“range”).
• The receiver antenna may be mounted inside or outside the model:
Internal antenna mounting:
The antenna may be routed down through the inside of the fuselage, or through any non-metallic
housing or tube within the
fuselage. Keep the antenna away from metal pushrods, wires and cables; otherwise, range may be decreased. Always perform a
range check before flying (see page 22).
External antenna mounting:
A. Use a cut off servo arm as a “stop
” or strain relief
inside the fuselage to keep
tension off the solder joint holding the antenna to the receiver. Guide the antenna
through a hole in the fuselage. (If possible, insulate the hole with a rubber grommet or a
small piece of rubber tubing.)

B. Make a hook
from another cut off servo arm. Insert the end of the antenna
through two holes, then connect the hook to a rubber band around a pin inserted into the
vertical stabilizer. Allow any excess antenna length to trail behind the hook.
• The receiver contains precision electronic parts. It is the most delicate (and expensive) radio component on-board the model
and should be protected from vibration, shock and temperature extremes. To protect the receiver, wrap it in R/C foam rubber or
other vibration-absorbing material. If appropriate, waterproof the receiver by placing it in a plastic bag and closing the open
end with a rubber band before wrapping it in foam. If moisture enters the receiver, intermittent operation or a failure may result.
Wrapping the receiver in a plastic bag also protects it from fuel and exhaust residue which, in some models, can work its way
into the fuselage.
Mounting the frequency clip:
(for USA)
• To announce your frequency and avoid potential interference problems, the
frequency number should always be displayed on the transmitter antenna while
flying. Peel the backing from the numbers and apply them to both sides of the
clip. Snap the end of the clip that fits best to the base of the antenna as shown.
You may cut off the other end of the clip.

REVR Servo Reversing
The servo reversing function is used to change the direction that a servo responds to a control input from the transmitter
(stick, dial or switch). After using the reversing function, check all
the controls on the model to be certain
they are operating
in the correct direction and that you did not inadvertently reverse a servo other than the one intended. Reversing the wrong
servo (and not checking the response of the controls before each flight) may be the most common cause of a crash!
To reverse a servo:
1. Enter the programming mode and use the MODE key to access the REVR
function.
2. Use the SELECT key to select the channel you wish to reverse.
3. Push the DATA INPUT lever downward to reverse the servo (REV), or push the lever upward
to make the servo operate normally (NOR). The arrow will indicate the condition of the servo
(normal or reversed). In the diagram channel 1 (aileron) is
“normal” (not reversed).
4. Use the SELECT key to display other channels to be reversed.
Dual Rates / Exponential Settings
The aileron, elevator and rudder dual rates on the 6EXAP are simultaneously activated by the dual rate switch. The amount of

EPA End Point Adjustment
Note:
Since changing the “end points” will also change the dual rates, the end points should be set prior to setting the dual
rates. If you set the dual rates first, and then go back and change the end points, the dual rate throws will also change.
The EPA function is designed to
“fine tune” the servo throws in cases where changing the pushrod hookup will not achieve the
correct throw. The pushrods should first be connected to the servo arms and control horns so the correct, or near correct control
surface throw will be achieved. THEN the EPAs may be used to make small changes in the servo throw until the desired control
throw is achieved. The control throws should be set up so that the
“end points” are as near to 100% as possible. If the EPA values
must be set below 70% or above 120% to get the desired throw, you should strongly consider changing the pushrod connections
so the values can be set closer to 100%. (When the EPA is set to 100% the maximum servo throw for channels 1, 2, 3 & 4 is
approximately 40
˚ and approximately 55 ˚ for channels 5 & 6.)

required on any one control it is a good idea to readjust the pushrods so the trims can be returned to neutral (zero). Adjusting
the trims with the trim levers changes the servo

To utilize the trainer function, the appropriate trainer cord (available separately) and a second Futaba transmitter (usually
provided by your flight instructor or R/C club) will be required. When two radios are connected with the trainer cord, they are
both capable of operating the model, but it's usually best for the instructor to hold the radio that has been setup for the plane
to be flown (as it is already programmed to fly the model). When the instructor holds the trainer switch on his radio, the student
will have control. When the instructor wishes to regain control he simply releases the switch. Then he will have immediate, full

Note:
When the instructor initially depresses the trainer switch on his transmitter, there will be a one-second delay before the
student takes control. In most situations this momentary delay will go unnoticed.
Throttle-cut function
The throttle-cut function is intended to be used for shutting off the engine. The engine can be conveniently shut off by pressing
the "THR Cut" button. The throttle-cut feature prevents inadvertently shutting off of the engine when lowering the throttle stick
all the way (such as when coming in for a landing or taxiing). Throttle-cut works only when the throttle stick is down. To set up
throttle-cut, turn on the transmitter and receiver. Actuate the throttle-cut function by rapidly depressing, then releasing the
switch twice. Observe the momentary position of the carburetor barrel on the engine. It should be fully closed (thus shutting off
the engine). If necessary, use the throttle E.P.A. (channel 3) to fully close the carburetor barrel when the throttle-cut is
activated. Now use the throttle trim to open the carburetor barrel so the engine will idle at the desired R.P.M. when the throttle
stick is all the way down.

When the flaperon mixing function is activated, the optional flap control lever

Changing the 6EXAP stick mode
The transmitter may be operated in four different stick “modes” (1, 2, 3 & 4). The modes
determine the functions that will be operated by control sticks. Currently, the transmitter is in
“mode 2” and should be left in mode 2 unless you are an experienced flyer and have learned to
fly in a different mode. In mode 2, the right control stick operates the aileron and elevator and
the left stick operates the rudder and throttle. This is how 99% of Americans fly their models.
To change the mode, simultaneously depress the MODE and SELECT keys, then turn on the power. The current mode will
appear on the LCD screen. Push the DATA INPUT lever up or down to change the mode. If a mode is selected that moves
the throttle control to the right stick, the throttle detent mechanism will have to be moved as well. This can be done by the

Charge the batteries
Second to the pilot's flight skills, one of the most important factors that can determine a model’s longevity is the state-ofcharge of the batteries - especially the on-board receiver pack. Inadequate charging and failing to monitor a battery's voltage
may lead to low battery power, causing loss of control and a crash. To avoid this, always charge the batteries the night before
you go flying. If ever uncertain how much "charge" is left in a battery, it is wiser to err on the side of caution, rather than trying
to get in one last flight! Due to the number of factors that determine receiver battery power consumption (such as the number
and type of servos in your model, the type of flying you do, how much resistance is built into the controls, the size of the
model, etc.), it is not possible to recommend how many flights one can get on a charge. The best way to monitor battery
power and calculate how much flight time you have left is to use a volt meter to check the batteries after each flight. This can
be done through the battery charging plug coming from the switch. There are many small, hand-held volt meters available
specially intended for R/C use. The Hobbico® Digital Voltmeter MKIII™ (HCAP0356) is one such unit. An on-board volt meter

to reveal any radio malfunctions, and to be certain the system has adequate operational range.
1.Turn on the transmitter, then the receiver. Leave the transmitter antenna all the way down. Walk away from the model while
simultaneously operating the controls. Have an assistant stand by the model and signal what the controls are doing to confirm
that they operate correctly. You should be able to walk approximately 20 - 30 paces from the model without losing control or
seeing
2.If everything operates correctly, return to the model. Set the transmitter in a safe, yet accessible location so it will be within
reach after starting the engine. Be certain the throttle stick is all the way down,
check with your assistant holding the plane and the engine running at various speeds. If the servos jitter or move
inadvertently, there may be a problem. Do not fly
certain you are the only one on your frequency, and that the battery has been fully charged.
3.When ready to fly, remember to fully extend the transmitter antenna. Avoid pointing the antenna directly at the model as the
signal is weakest in that direction.
Do not fly in the rain!
Moisture may enter the transmitter through the antenna or stick openings and cause erratic operation or loss of control. If you
must fly in wet weather during a contest, be sure to cover the transmitter with a plastic bag or other waterproof cover.
MODEL DATA RECORDING SHEET
After finalizing the programming for each model, fill out the values and settings in the Model Data Recording Sheets
back of the manual. The data sheets will serve as a backup in case a program is ever lost or inadvertently reset, or in case
you have to intentionally reset a program to make room for another model. Make additional copies before filling out the
sheets.

Receiver crystals:
The receiver frequency may be changed as long as it remains within the “low” and “high” band frequency range. If your
receiver is on any channel from 11 through 35, it is a
channel from 11 through 35 without having to perform any other service. Simply purchase a crystal on the desired channel,
then replace the existing crystal in your receiver with the new one. If your receiver is on any channel from 36 through 60, it is
“high band” receiver and the frequency may be changed to any other channel from 36 through 60. To order a receiver
