INTRODUCTION

Thank you for purchasing the Mini Switch! Following the

success of the larger, original Switch plane, the Mini Switch
gives you two different fl ying experiences in one plane. The
change from high wing confi guration to low wing confi guration
requires only a screw driver and a few minutes. Both high
and low wing confi gurations are very maneuverable and can
satisfy the leisure pilot and the more sporty, aerobatic pilot.
Should the model become damaged, repairs can be made
quickly with regular CA glue.

For the latest technical updates or manual corrections to the
Mini Switch visit the Hobbico web site at fl yzoneplanes.com.
Open the “Airplanes” link, then select the Mini Switch. If there
is new technical information or changes to this model a “tech
notice” box will appear in the upper left corner of the page.

AMA

We urge you to join the AMA (Academy of Model Aeronautics)
and a local R/C club. The AMA is the governing body of
model aviation and membership is required to fl y at AMA
clubs. Though joining the AMA provides many benefi ts,
one of the primary reasons to join is liability protection.
Coverage is not limited to fl ying at contests or on the club
fi eld. It even applies to fl ying at public demonstrations and
air shows. Failure to comply with the Safety Code (excerpts
printed in the back of the manual) may endanger insurance
coverage. Additionally, training programs and instructors
are available at AMA club sites to help you get started
the right way. There are over 2,500 AMA chartered clubs
across the country. Contact the AMA at the address or toll­free phone number below:

IMPORTANT!!! Two of the most important things you can

do to preserve the radio controlled aircraft hobby are to
avoid fl ying near full-scale aircraft and avoid fl ying near or
over groups of people.

SAFETY PRECAUTIONS

PROTECT YOUR MODEL, YOURSELF & OTHERS…

FOLLOW THESE IMPORTANT SAFETY PRECAUTIONS

1. Your Mini Switch should not be considered a toy, but rather
a sophisticated, working model that functions very much like
a full-size airplane. Because of its performance capabilities,
the Mini Switch, if not assembled and operated correctly,
could possibly cause injury to yourself or spectators and

damage to property.

2. You must assemble the model according to the

instructions. Do not alter or modify the model, as doing
so may result in an unsafe or unfl yable model. In a few
cases the instructions may differ slightly from the photos.
In those instances the written instructions should be
considered as correct.

2

3. You must take time to build straight, true and strong.

4. You must use an R/C radio system that is in fi rst-class
condition, and a correctly sized motor and components
throughout the building process.

5. You must correctly install all R/C and other components
so that the model operates correctly on the ground and in
the air.

6. You must check the operation of the model before every
fl ight to ensure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
clevises or other connectors often and replace them if they
show any signs of wear or fatigue.

7. If you are not an experienced pilot or have not fl own
this type of model before, we recommend that you get
the assistance of an experienced pilot in your R/C club for
your fi rst fl ights. If you’re not a member of a club, your local
hobby shop has information about clubs in your area whose
membership includes experienced pilots.

8. While this kit has been fl ight tested to exceed normal use,
if the plane will be used for extremely high stress fl ying, such
as racing, or if a motor larger than one in the recommended
range is used, the modeler is responsible for taking steps to
reinforce the high stress points and/or substituting hardware
more suitable for the increased stress.

We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and fl yability of your fi nished model depends
on how you build it; therefore, we cannot in any way
guarantee the performance of your completed model,
and no representations are expressed or implied as to the
performance or safety of your completed model.

Remember: Take your time and follow the instructions to
end up with a well-built model that is straight and true.

ADDITIONAL ITEMS REQUIRED

Radio Control System

The Mini Switch Tx-R (transmitter ready) comes with the

servos and a Tactic™ TR624 receiver installed, so all that is
required is a basic 4+channel transmitter. The Tactic TTX404

2.4GHz spread spectrum 4-channel radio control system
(TACJ2404) is included with the RTF (ready to fl y) version of
the Mini Switch, so this same radio system will work for your

Tx-R version, too.

❍ Tactic TTX404 2.4GHz 4-channel system (TACJ2404)

❍ (4) AA batteries will be required to operate the

recommended transmitter (FUGP4304).

A more versatile transmitter is the Tactic TTX650 digital

programmable transmitter. The TTX650 is loaded with features
which will be useful with the Mini Switch such as a fl ight timer,
dual rates, end-point adjustment, and exponential. Built-in
mixes and user programmable mixes will accommodate your
radio needs for future, more advanced models as well.

❍ Tactic TTX650 2.4GHz 6-channel computer Tx only

(TACJ2650)

If you already own a transmitter that you plan to use with the
Mini Switch, fi rst make sure it is in the compatibility list at www.

Tx-Ready.com/anylink-chart.html. If so, you can purchase

the AnyLink 2.4GHz Universal Radio Adapter to allow your
transmitter to communicate with the pre-installed Tactic receiver.

Battery and Charger

The Mini Switch RTF comes complete with a motor battery

and charger. The Tx-R version requires a 1300 mAh 11.1V
LiPo battery and LiPo Charger. The Mini Switch was designed
for the Flyzone 1300mAh 11.1V LiPo battery (FLZA6014).
Other LiPo batteries similar in size with the same voltage
and capacity may also work, but they may not fi t properly in
the battery compartment or have the same type of battery
connector. In addition to a battery, a LiPo battery charger is also
required and there are several that will work (depending on your

budget and requirements). A safe, economical charger is the

ElectriFly® 3S (3-cell/11.1V) LiPo Smart Charger (GPMM3318).

The Smart Charger includes adapters to charge from a 110V

wall outlet or a 12V DC outlet from a car. The Smart Charger
will take approximately 3-1/2 hours to fully charge the battery.

The Smart Charger will time out after 2 hours and 40 minutes

when charging the recommended battery. An additional hour
on the charger will bring the capacity of the battery to near full.
Some pilots prefer to have several batteries and charge them
faster so they can fl y more. For charging up to four batteries
faster at the same time, the Great Planes PolyCharge4™ DC-

powered LiPo charger (GPMM3015) is recommended. But
unlike the Smart Charger, the PolyCharge4 does not have
an internal LiPo cell balancer which is a critical component in
making sure your LiPo batteries charge effi ciently and evenly.
So, for each LiPo battery you wish to charge simultaneously,
one Great Planes Equinox™ LiPo Cell Balancer (GPMM3160)
will also be required. Finally, the PolyCharge4 does not have

AC capability, so if wall charging is a priority, a separate AC
12-Volt power source must also be purchased separately. A

suitable power supply for the PolyCharge4 is the Great Planes

12V 12A DC power supply (GPMP0901).

ASSEMBLE THE MODEL

Install the Tail Section

3. Use two 3 x 30 mm machine screws to secure the

❏

stabilizer in place.

Setting Up the High Wing Confi guration

We recommend fl ying the Mini Switch fi rst in the high wing
confi guration. The high wing position will make the orientation
of the airplane more visible at high altitudes.

1. Slide the horizontal stabilizer between the tail pushrods

❏

and the stabilizer pocket. You will need to slightly fl ex the
pushrods in order get the stabilizer in position.

2. When fi tting the horizontal stabilizer into the pocket,

❏

guide the tail wheel tiller arm through the plastic hoop on the
underside of the rudder.

1. Connect the clevises on the pushrods to the outer holes

❏

in the elevator and rudder control horns. Squeeze the ends
of the clevises to ensure they are snapped together properly.

5

2. Slide the carbon wing joiner through the tube in the

❏

high wing canopy hatch and center its position.

4. Install one of the wing panels onto the wing joiner tube.

❏

Feed the aileron servo lead through the hole in the center of
the canopy hatch. The alignment pin fi ts into the small tube

pre-glued in the wing. Push the joiner tube into the wing until

it bottoms out against the outer screws in the wing panels.

5. With both panels securely in place, tighten the inner

❏

screws in the wing panels. Pull on the wing panels to confi rm
they won’t separate in fl ight.

3. Tighten the outer screws on the underside of the wing

❏

panels. Loosen the inner screws.

6. Attach the aileron servo leads to the Y-harness

❏

connected to the receiver. Ensure the orange wires in the
servo leads align with the white wires in the Y-harness.

6

2. Fit the prop adapter onto the motor shaft followed by

❏

the drive washer.

7. Test fi t the canopy hatch onto the fuselage by inserting

❏

the tongue at the front of the hatch into the pocket in the
fuselage and pressing the aft end of the hatch down in place.
Secure the hatch using the included wing screw.

Install the Propeller

1. Disassemble the spinner and prop adapter, making

❏

note of how it is installed. You will need to reassemble it onto
the motor in the same order.

3. Install the spinner backplate onto the prop adapter

❏

followed by the propeller, prop washer, prop spacer, and prop
nut. Tighten the prop nut thoroughly. If the spinner backplate
contacts the foam fuselage after tightening the prop nut,

loosen the nut and slide the prop assembly forward some.

Then, re-tighten the nut.

4. Tighten the spinner cone onto the assembly using the

❏

included screws.

7

5. You have now completed the assembly of the high

❏

wing confi guration of the Mini Switch!

CHANGING TO THE LOW WING

CONFIGURATION

Once you are accustomed to fl ying the high wing confi guration,
it’s time to move the wings and give the low wing confi guration
a try. You will fi nd that the lower wing position changes the
aerobatic characteristics of the plane. In general, the low
wing will perform most aerial maneuvers better than the high
wing. You may fi nd the control response a little slower, but
also smoother, than the high wing.

1. Remove the wing panels from the high wing

❏

confi guration canopy hatch by disconnecting the aileron

Y-harness, loosening the wing joiner screw and sliding the

panels off of the joiner tube.

3. Loosen the outer wing screws three complete turns.

❏

4. Insert the wing joiner tube through the joiner tube

❏

holes in the fuselage.

2. Remove the battery hatch by sliding the lever forward

❏

and lifting the hatch away. Push the wing pocket plugs out
and set them aside for later use.

5. Slide the wing panels onto the wing joiner. The

❏

aileron servo leads should fi t through the slots in the
fuselage sides. Be sure the panels are fully seated against
the fuselage inside the wing pockets. Tighten the inner
wing screws against the wing joiner tube. Pull on the wing

panels to confi rm they won’t separate in fl ight.

8

2. Familiarize yourself with the charging procedure of the

❏

included LiPo battery. Read the charger manual completely.

6. Connect the Y-harness to the aileron servo leads. Test

❏

fi t the low wing confi guration canopy hatch to the fuselage
and screw it in place. NOTE: The low wing confi guration

will require you to readjust your control surface trims.
Be prepared for this on your fi rst fl ight.

7. Move the clevis to the innermost hole in the rudder

❏

control horn. The additional rudder movement will improve
performance in the low wing confi guration. Be sure to move
the clevis back to the outer hole if returning to the high wing
confi guration.

GET THE MODEL READY TO FLY

3. Fully charge the LiPo battery.

❏

4. Test fi t the battery in the airplane. The battery wires

❏

should be tucked neatly along the side of the battery.

Lithium Battery Handling & Usage

WARNING!! Read the entire instruction sheet included with
the battery. Failure to follow all instructions could cause

permanent damage to the battery and its surroundings, and
cause bodily harm!

Prepare the Transmitter

and LiPo Battery

1. Install fresh AA batteries into the transmitter. Follow

❏

the diagram molded inside the battery compartment.

● ONLY use a LiPo approved charger. NEVER use
a NiCd/NiMH peak charger!

● NEVER charge in excess of 4.20V per cell.

● ONLY charge through the “charge” lead. NEVER

charge through the “discharge” lead.

● NEVER charge at currents greater than 1C.

● ALWAYS set charger’s output volts to match

battery volts.

● ALWAYS charge in a fi re proof location.

● NEVER trickle charge.

● NEVER allow battery temperature to exceed

150°F (65°C).

● NEVER disassemble or modify pack wiring in any
way or puncture cells.

9

● NEVER discharge below 2.75V per cell.

● NEVER place on combustible materials or leave

unattended during charge or discharge.

● ALWAYS KEEP OUT OF REACH OF CHILDREN.

Check the Control Directions

1. With the battery fully charged, turn on your

❏

transmitter and move the throttle stick (left stick) down
to the idle position. Then, plug the motor battery into the
ESC. If the ESC makes an erratic pattern of beeps after the
initial startup beeps and a few seconds of silence, then it
has entered programming mode and the throttle channel
needs to be reversed on the transmitter, following Step 2.
If not, skip Step 2. Take care around the propeller! The

propeller will rotate when the throttle is advanced.

(Complete ESC programming instructions are included on
page 15 of this manual)

3. View the model from behind and move the rudder

❏

control (left stick) on the transmitter to the left. The rudder
should move to the left. If not, move the rudder reversing
switch on the transmitter and then test the operation of the
rudder again.

2. Disconnect the battery from the ESC. Then, move the

❏

throttle reversing switch on the transmitter. Confi rm that the
throttle stick is still in the idle position and reconnect the
battery to the ESC.

❏

should cause the left aileron to move down and the right
aileron to move up. Flip the aileron reversing switch on the
transmitter if necessary.

6. When checking the propeller operation, BE SURE

❏

TO KEEP YOUR HANDS, CLOTHING, ETC. BEHIND
THE SPINNING ARC OF THE PROPELLER! Operate the

propeller outside, clear of any obstacles, and be sure that
you have a fi rm grasp on the airplane before applying throttle.

OPERATING THE ESC

NECESSARY TRANSMITTER SETTINGS

If you are using a transmitter other than a Tactic transmitter,
it’s very important to set the transmitter’s throttle channel
adjustments, as follows:

1. Set the throttle channel’s travel adjustment (ATV,EPA or
ATL) to 100%.

2. Set the throttle trim and sub-trim to neutral or zero.

These are the recommended control surface throws:

3. Set the throttle channel’s reversing switch to reverse on
Futaba® transmitters. Other transmitters might require you
to set the throttle reversing switch to normal.

LOW VOLTAGE CUT-OFF

The Mini Switch ESC includes a low-voltage cut-off feature

that stops motor rotation if the battery’s voltage drops too low.

This protects the battery from damage due to under-voltage

conditions. When the low voltage cut-off stops motor rotation
it will still supply power to the receiver and all control surfaces
except throttle, so you can maintain control of the aircraft.

NORMAL STARTUP PROCEDURE

1. Unless calibrating the throttle or programming the ESC,
always turn on the transmitter with the throttle stick all the
way down. Turn on the transmitter.

2. Connect the battery to the ESC. Listen for the three
tones…“ 1 2 3” followed by three short beeps…“beep
beep” beep” followed by one long beep…“beeep”.

Now the ESC is “armed” and the model is ready to fl y. The
propeller will turn whenever the throttle stick is advanced,
so use caution. When you are done running the motor or
fl ying the plane simply disconnect the battery and turn off
the transmitter.

Check the Balance (C.G.)

More than any other factor, the C.G. (center of gravity/
balance point) can have the greatest effect on how a

model fl ies and could determine whether or not your fi rst
fl ight will be successful. If you value your model and wish
to enjoy it for many fl ights, DO NOT OVERLOOK THIS
IMPORTANT PROCEDURE. A model that is not properly
balanced may be unstable and possibly unfl yable.

With the battery installed along with the propeller, spinner and
hatch, the Mini Switch is designed to balance at the position
shown without you needing to add any additional ballast to
the nose or tail.

Check the Control Throws

The Mini Switch is setup from the factory with the

recommended control throws for the high wing
configuration. If at any time you wish to return to
the default control throws, or if you simply want to
confirm the throws, use the following measurements:

NOTE: The throws are measured at the widest part of the
elevators, rudder and ailerons.

1. For the high wing version, apply narrow (1/16" [2mm])

❏

strips of tape 2" [51mm] from the leading edge of each wing

panel onto the underside of the wings as shown (you can
also apply some masking tape and draw the lines with a
felt-tip pen). If you are balancing the plane in the low wing
confi guration, apply the strips of tape 2-11/16" [68mm] fron
the wing’s leading edge on the top of the wings.

11

2. With the wings attached to the fuselage, all parts of the

❏

model installed (ready to fl y) and the battery installed, lift the
model with two fi ngers at the lines you made.

3. If the plane does not sit level with your fi ngers on the

❏

lines, you can shift them forward or aft 1/8” [3mm]. If the tail
continues to drop even with your fi ngers 1/8” [3mm] aft of the
lines, the model is “tail heavy”. You will need to add weight to
the nose. If the nose continues to drop even with your fi ngers
all the way to the forward lines, the model is “nose heavy”.

You will need to move the receiver aft.

4. If you found it necessary to add weight or move the

❏

receiver, recheck the C.G. to confi rm the plane now balances
between the lines. Do not fl y a plane that has not been

properly balanced!

Balance Propellers

Carefully balance your propeller and spare propellers before
you fl y. An unbalanced prop can be the single most signifi cant
cause of vibration that can damage your model. Not only
will motor mounting screws and bolts loosen, possibly with

disastrous effect, but vibration may also damage your receiver
and battery.

We use a Top Flite® Precision Magnetic Prop Balancer
(TOPQ5700) in the workshop and keep a Great Planes®
Fingertip Prop Balancer (GPMQ5000) in our fl ight box.

Range Check

Balance the Model Laterally

1. With the wing level, have an assistant help you lift the

❏

model by the engine propeller shaft and the bottom of the
fuse under the TE of the fi n. Do this several times.

2. If one wing always drops when you lift the model, it

❏

means that side is heavy. Balance the airplane by adding
weight to the other wing tip. Stick-on lead weight can be
purchased from your hobby supplier (GPMQ4485). An

airplane that has been laterally balanced will track better
in loops and other maneuvers.

PREFLIGHT

Identify Your Model

No matter if you fly at an AMA sanctioned R/C club site
or if you fly somewhere on your own, you should always
have your name, address, telephone number and AMA
number on or inside your model. It is required at all AMA
R/C club flying sites and AMA sanctioned flying events.
Fill out the identification tag on page 24 and place it on
or inside your model.

The “range” is the safe operating distance from the transmitter

to the receiver, and should be as far as you can clearly see
the model. With the assistance of another person, place the
aircraft on the ground and walk 100 feet (30m) away from
the model. With the transmitter pointed directly at the model,
operate the transmitter’s controls, and ensure the movement
of all surfaces is according to the movement of the transmitter.

MOTOR SAFETY PRECAUTIONS

Failure to follow these safety precautions may result in
severe injury to yourself and others.

● Get help from an experienced pilot when learning
to operate motors.

● Use safety glasses when starting or running motors.

● Do not run the motor in an area of loose gravel or

sand; the propeller may throw such material in your
face or eyes.

● Keep your face and body as well as all spectators
away from the plane of rotation of the propeller as
you run the motor.

● Keep these items away from the prop: loose clothing,
shirt sleeves, ties, scarfs, long hair or loose objects
such as pencils or screwdrivers that may fall out of
shirt or jacket pockets into the prop.

12

● The motor gets hot! Do not touch it during or right
after operation.

● Do not throw anything into the propeller of a
rotating motor.

9) Under no circumstances may a pilot or other person
touch a powered model in fl ight; nor should any part of the

model other than the landing gear intentionally touch
the ground, except while landing.

AMA SAFETY CODE (EXCERPTS)

Read and abide by the following excerpts from the Academy
of Model Aeronautics Safety Code. For the complete Safety
Code refer to Model Aviation magazine, the AMA web site or
the Code that came with your AMA license.

General

1) I will not fl y my model aircraft in sanctioned events,
air shows, or model fl ying demonstrations until it has
been proven to be airworthy by having been previously,
successfully fl ight tested.

2) I will not fl y my model aircraft higher than approximately

400 feet [120m] within 3 miles [4.8km] of an airport without

notifying the airport operator. I will give right-of-way and avoid
fl ying in the proximity of full-scale aircraft. Where necessary,
an observer shall be utilized to supervise fl ying to avoid
having models fl y in the proximity of full-scale aircraft.

3) Where established, I will abide by the safety rules for the
fl ying site I use, and I will not willfully and deliberately fl y my
models in a careless, reckless and/or dangerous manner.

5) I will not fl y my model unless it is identifi ed with my name
and address or AMA number, on or in the model. Note: This
does not apply to models while being fl own indoors.

7) I will not operate models with pyrotechnics (any device
that explodes, burns, or propels a projectile of any kind).

Radio Control

1) I will have completed a successful radio equipment ground
check before the fi rst fl ight of a new or repaired model.

CHECK LIST

During the last few moments of preparation your mind
may be elsewhere anticipating the excitement of the fi rst
fl ight. Because of this, you may be more likely to overlook
certain checks and procedures that should be performed
before the model is fl own. To help avoid this, a check list
is provided to make sure these important areas are not
overlooked. Many are covered in the instruction manual,
so where appropriate, refer to the manual for complete
instructions. Be sure to check the items off as they are
completed (that’s why it’s called a check list!).

1. Check the C.G. according to the measurements

❏

provided in the manual.

2. Be certain the battery and receiver are securely

❏

installed in the fuse.

3. Balance your model laterally as explained in the

❏

instructions.

4. Confi rm that all controls operate in the correct direction

❏

and the throws are set up according to the manual.

5. Make sure any servo extension cords you may have

❏

used do not interfere with other systems (servo arms,

pushrods, etc.).

6. Balance your propeller (and spare propellers).

❏

7. Tighten the propeller nut and spinner.

❏

8. Place your name, address, AMA number and

❏

telephone number on or inside your model.

9. If you wish to photograph your model, do so before

❏

your fi rst fl ight.

10. Range check your radio when you get to the

❏

flying field.

2) I will not fl y my model aircraft in the presence of
spectators until I become a qualifi ed fl ier, unless assisted by
an experienced helper.

3) At all fl ying sites a straight or curved line(s) must be
established in front of which all fl ying takes place with the
other side for spectators. Only personnel involved with fl ying
the aircraft are allowed at or in the front of the fl ight line.
Intentional fl ying behind the fl ight line is prohibited.

4) I will operate my model using only radio control
frequencies currently allowed by the Federal
Communications Commission.

5) I will not knowingly operate my model within three

miles of any pre-existing fl ying site except in accordance
with the frequency sharing agreement listed [in the

complete AMA Safety Code].

13

FLYING

CAUTION (THIS APPLIES TO ALL R/C AIRPLANES):
If, while fl ying, you notice an alarming or unusual sound
such as a low-pitched “buzz,” this may indicate control
surface fl utter. Flutter occurs when a control surface (such
as an aileron or elevator) or a fl ying surface (such as a
wing or stab) rapidly vibrates up and down (thus causing
the noise). In extreme cases, if not detected immediately,
fl utter can actually cause the control surface to detach
or the fl ying surface to fail, thus causing loss of control
followed by an impending crash. The best thing to do when
fl utter is detected is to slow the model immediately by
reducing power, then land as soon as safely possible.
Identify which surface fl uttered (so the problem may
be resolved) by checking all the servo grommets for
deterioration or signs of vibration. Make certain all pushrod
linkages are secure and free of play. If it fl uttered once,
under similar circumstances it will probably fl utter again
unless the problem is fi xed. Some things which can cause
fl utter are; Excessive hinge gap; Not mounting control
horns solidly; Poor fi t of clevis pin in horn; Side-play of
wire pushrods caused by large bends; Excessive free play
in servo gears; Insecure servo mounting; and one of the
most prevalent causes of fl utter; Flying an over-powered
model at excessive speeds.

Takeoff

Before you get ready to takeoff, see how the model handles
on the ground by doing a few practice runs at low speeds
on the runway. Hold “up” elevator to keep the tail wheel on
the ground. If necessary, adjust the tail wheel so the model
will roll straight down the runway. If you need to calm your
nerves before the maiden fl ight, shut the motor down and
bring the model back into the pits. Top off the battery, then
check all fasteners and control linkages for peace of mind.

Remember to takeoff into the wind. When you’re ready,
point the model straight down the runway, hold a bit of up
elevator to keep the tail on the ground to maintain tail wheel
steering, and then gradually advance the throttle. As the
model gains speed decrease up elevator, allowing the tail
to come off the ground. One of the most important things
to remember with a tail dragger is to always be ready to
apply right rudder to counteract motor torque. Gain as much
speed as your runway and fl ying site will practically allow
before gently applying up elevator, lifting the model into the
air. At this moment it is likely that you will need to apply more
right rudder to counteract motor torque. Be smooth on the
elevator stick, allowing the model to establish a gentle climb
to a safe altitude before turning into the traffi c pattern.

Take it easy with the Mini Switch for the fi rst few fl ights,

gradually getting acquainted with it as you gain confi dence.

Adjust the trims to maintain straight and level fl ight. After

fl ying around for a while, and while still at a safe altitude with

plenty of battery charge, practice slow fl ight and execute

practice landing approaches by reducing the throttle to see
how the model handles at slower speeds. Add power to see
how she climbs as well. Continue to fl y around, executing
various maneuvers and making mental notes (or having your
assistant write them down) of what trim or C.G. changes may

be required to fi ne tune the model so it fl ies the way you like.
Mind your fuel level, but use this fi rst fl ight to become familiar
with your model before landing.

Landing

To initiate a landing approach, lower the throttle while on

the downwind leg. Allow the nose of the model to pitch

downward to gradually bleed off altitude. Continue to lose
altitude, but maintain airspeed by keeping the nose down
as you turn onto the crosswind leg. Make your fi nal turn
toward the runway (into the wind) keeping the nose down
to maintain airspeed and control. Level the attitude when
the model reaches the runway threshold, modulating the
throttle as necessary to maintain your glide path and
airspeed. If you are going to overshoot, smoothly advance
the throttle (always ready on the right rudder to counteract
torque) and climb out to make another attempt. When
you’re ready to make your landing fl are and the model is a
foot or so off the deck, smoothly increase up elevator until

it gently touches down. Once the model is on the runway
and has lost fl ying speed, hold up elevator to place the tail
on the ground, regaining tail wheel control.

One fi nal note about fl ying your model. Have a goal or fl ight

plan in mind for every fl ight. This can be learning a new
maneuver(s), improving a maneuver(s) you already know,
or learning how the model behaves in certain conditions
(such as on high or low rates). This is not necessarily to

improve your skills (though it is never a bad idea!), but more

importantly so you do not surprise yourself by impulsively
attempting a maneuver and suddenly fi nding that you’ve run
out of time, altitude or airspeed. Every maneuver should be

deliberate, not impulsive. For example, if you’re going to do a

loop, check your altitude, mind the wind direction (anticipating
rudder corrections that will be required to maintain heading),
remember to throttle back at the top, and make certain you
are on the desired rates (high/low rates). A fl ight plan greatly
reduces the chances of crashing your model just because
of poor planning and impulsive moves. Remember to think.

Have a ball! But always stay in control

and fl y in a safe manner.

Flight

For reassurance and to keep an eye on other traffi c, it is a
good idea to have an assistant on the fl ight line with you. Tell
him to remind you to throttle back once the plane gets to a
comfortable altitude. While full throttle is usually desirable for
takeoff, most models fl y more smoothly at reduced speeds.

GOOD LUCK AND GREAT FLYING!

The ESC included with the Mini Switch is pre-programmed

to the correct settings to work best with the Mini Switch—
other than calibrating the throttle (only if using a transmitter
different than the Tactic that comes with the Mini Switch),
there is nothing that needs to be done with the ESC. However,
should you ever desire to reprogram the ESC to suit different
requirements, following are full programming instructions.

FACTORY DEFAULT SETTINGS

Motor Brake:

Battery Type:

LVC (Low-Voltage Cutoff):

If using a transmitter different than the Tactic
included with the RTF version, the throttle must
be calibrated.

CAUTION: All adjustments to the ESC should be conducted
with the propeller removed from the motor or one of the three
motor wires disconnected from the ESC to prevent the motor
from starting inadvertently.

1. Turn on your transmitter and move the throttle stick to full­throttle.

2. Connect the battery. The ESC will emit three rapid tones
(“ 1 2 3”) indicating that all is well, followed by two short
beeps (“beep beep”) indicating that the top point of the
throttle range has been detected and set.

3. You have about four seconds to return the throttle stick all

the way down. Then the ESC will emit three more beeps

(indicating the number of LiPo cells) followed by one long

beep (“beeep”) indicating that the low point of the throttle
range has been detected. Simply disconnect the battery
to end the procedure. Now the throttle has been calibrated
and the Mini Switch is ready to fl y.

TROUBLESHOOTING GUIDE

Problem Reason

Motor does not work, no tones or
beeps are coming from the ESC.

Action

Check the battery or plugs or change the plugs if the
wires are damaged.

The ESC is not receiving power
from the battery.

Problem Reason

Motor does not work, Alert Tone sounds
(“beep-beep,” “beep-beep,” “beep-beep,”…).

Action

Make sure the battery is charged and/or you are using
the correct battery.

Battery Voltage is too
high or too low.

Example

To set the motor brake from the factory default of “off” to “on”:

1. Advance the throttle stick. Turn on the transmitter.

2. Connect the battery. Listen for the three tones (“ 1 2 3”)
followed by two short beeps (“beep beep”) followed by a
5-second pause followed by fi ve tones (“ 1 2 3 4 5”). The
ESC is now in the Programming Menu.

3. After you hear one short beep (“beep”) indicating the

motor brake function, lower the throttle stick.

4. Listen for the beeps: one beep = brake off, two beeps
= brake on. If you do nothing the ESC will simply loop

through the sequence of beeps—once, then twice, then
once, then twice, etc. waiting for your command to turn the
brake on or off. To turn the brake on, advance the throttle
stick after the two beeps. Listen for the tones (“ 1 2 1 2”)
indicating that the setting has been set and saved. If that’s
all you wanted to set, immediately lower the throttle stick
(within two seconds) to exit programming mode, then hear
three short beeps (“beep beep beep”) followed by one
long beep (“beeep”) indicating that the model is ready to
fl y .

Auto-Protection

The ESC features Auto-Protection to discontinue power to

the motor under certain conditions:

Problem Reason

Motor does not work, Alert Tone
sounds (long beeps: “beeeep­beeeep-beeeep…).

Action

Make sure the transmitter is turned on and that the
receiver is linked to the transmitter and receiving a signal.

The ESC is receiving power from
the battery, but is not receiving a
signal from the receiver.

Problem Reason

Motor does not work, Alert Tone
sounds (rapid beeps:
“beepbeepbeepbeepbeep…).

Action

Lower the throttle stick all the way, or recalibrate the
throttle per calibration instructions.

Throttle stick is not in the lowest
position, or throttle needs to be
calibrated.

Problem Reason

Motor does not work, five tones
are sounded (“ 1 2 3 4 5”)
after the two beeps.

Action

Set the throttle direction the other way in the transmitter.

The direction of the throttle channel
is reversed and the ESC has entered
the Programming Menu.

Problem Reason

The motor turns the wrong
direction.

Action

Swap any two of the motor/ESC wire connections with
each other.

The three motor wires are
incorrectly connected to the ESC.

1. Start up failure: If the motor fails to start within 2 seconds

of advancing the throttle the ESC will automatically cut
power. To restart, lower the throttle stick, then advance
again. This can happen if there is a poor connection
between the ESC and motor or if the propeller or motor is
impeded for any reason.

2. Over-heat protection: If the ESC temperature ever rises
to about 110 Celsius the ESC will automatically reduce
power.

3. Signal loss: Power to the motor will be reduced if the
throttle signal is lost for 1 second. If the signal is lost for 2
seconds motor power will be cut completely.

TTX404 TRANSMITTER (Tx)

The TTX404 airplane transmitter is available in either a “Mode

2” confi guration with throttle on the left and elevator on the
right, or “Mode 1” confi guration with throttle on the right and
elevator on the left. Mode 2 radios are most commonly used

in the U.S., whereas Mode 1 radios are popular in other

countries. Be sure the radio purchased is of the correct mode.

Four “AA” batteries are required to power the Tx (not included).
Non-rechargeable 1.5V alkaline, or 1.2V rechargeable nickel­cadmium (NiCd) or nickel-metal hydride (NiMH) cells, can be
used. Do not mix cell types, or old and new cells, etc. See
the SERVOS AND ACCESSORIES section on page 16 for
optional batteries available at local hobby retailers.

To install the batteries, slide the battery door down. Insert the

cells as shown in the diagram, making sure to note proper

polarity for each cell. Close the battery door.

POWER SWITCH, LED, and LOW BATTERY ALARM

The red power LED should light when the power switch is

moved upwards to the “ON” position. The Tx should have
adequate power for fl ight when the LED is on constantly.

17

Anytime the LED begins to fl ash, accompanied by the

sounding of an audible tone, the Tx battery voltage has
dropped too low and operation of the model should NOT

be attempted!

WARNING! Never operate an R/C model

with weak Tx batteries! Reduced operational

range and/or possible loss of control of the

aircraft could result. Replace weak alkaline
batteries, or re-charge NiCd or NiMH batteries before
attempting a fl ight!

causing the nose of the airplane to point to the right. Moving
the rudder stick to the left will cause the nose of the airplane
to turn left. When using the rudder in conjunction with the
ailerons, the airplane’s nose can point into a turn (instead
of pointing up and “skidding” through the turn), allowing the
airplane to perform tighter, more coordinated turns.

TRIMS

A “trim” lever is included for each of the main controls, located

adjacent to the respective stick.

If during a fl ight the Tx LED starts to fl ash, accompanied
by the sounding of audible tones, it’s a warning that the Tx
batteries have become weak and the aircraft should be landed
as soon as possible!

AILERON (CH1)

Controls the moveable surfaces at the end of both main wings
to rotate the airplane about the “roll” axis (an imaginary line
which extends from the airplane’s nose to the tail). Since
every airplane is different, the aileron reversing switch must
be set so that moving the aileron stick to the right will cause
the airplane’s right aileron to defl ect up, thus causing the right
wing to drop and the airplane will bank to the right. Moving
the aileron stick to the left will cause the airplane’s left wing to
drop and the airplane will bank to the left. This is one important
method for turning the aircraft.

ELEVATOR (CH2)

Controls the moveable horizontal surfaces on the airplane’s
tail to rotate the airplane about the “pitch” axis (an imaginary
line extending through the center of both main wings, from one
wing tip to the other wing tip). Position the elevator reversing
switch so that pulling the elevator stick back (towards you)
will cause the elevators to defl ect up, thus causing the nose
of the airplane to rise. Pushing the elevator stick forwards
(away from you) will cause the nose of the airplane to drop.
When using the ailerons to bank the airplane’s wings, pulling
the elevator stick back will help the aircraft maintain altitude
and turn the aircraft more quickly.

THROTTLE (CH3)

The aileron, elevator, and rudder trim levers are digital in

function, and always rest at center position. Briefl y defl ecting
the lever to either direction away from center will cause the
respective servo output to fi nely rotate to one direction, and
will be accompanied by an audible tone. Pressing and holding
the trim lever will cause the servo output to move repeatedly.
During a fl ight, when the main sticks are released and spring

back to center position, the aircraft should ideally not veer in
any direction. If the aircraft does veer in a particular direction,
click the respective trim lever until the aircraft maintains a
straight attitude on its own.

The throttle trim lever is analog in function, and can move

mechanically up or down and rest at any point in the range.
Moving the throttle trim lever slightly up or down will fi nely
adjust the engine or motor at low speeds. For safety reasons,

it’s a good idea to use throttle trim when controlling the engine/
motor at very low speed while on the ground. For aircraft with
glow engines, the precise position of the trim lever is helpful
when determining the engine’s preferred idle point. The throttle
trim lever is not active when the main throttle stick is above
the center point.

REVERSING SWITCHES

Four reversing switches are built into the Tx, one for each
control. Each switch can reverse the rotational direction of
the servo that is connected to the respective channel. This

is often a much easier method for changing the direction of
a servo’s movement as opposed to altering the mechanical
connections between the model’s surface and the servo. Refer
to the model’s instructions for specifi c details.

Controls the speed (R.P.M.) at which the engine or electric
motor operates. With the throttle reversing switch in the NOR
position, pulling the throttle stick back will cause the engine’s
speed to decrease. Pushing the throttle stick forward will cause
the engine’s speed to increase.

RUDDER (CH4)

Controls the sideways movement of the airplane’s tail and
will rotate the airplane about the “yaw axis” (an imaginary
line from the top of the airplane’s fuselage to the bottom of
the fuselage, located near the center-point of the fuselage).
Position the rudder reversing switch so that moving the rudder
stick to the right causes the rudder to defl ect to the right, thus

18

The length of both gimbal sticks can be adjusted as desired.

Loosen the set screw inside the center of the stick with a
2mm hex wrench. Rotate the stick end counter-clockwise to
lengthen the stick, or clockwise to shorten the stick. Once
the desired stick length is found, tighten the set screw with
the hex wrench.

ADJUSTABLE STICKS

side of the Tx – making sure not to allow any object to be

inserted inside the jack itself. Next, insert the cells inside
the Tx’s battery compartment noting proper polarity. Make
sure the transmitter’s power switch is in the OFF position.
Connect a compatible charge lead to the jack and follow the

instructions included with the charger for charging of NiCd or
NiMH batteries that are rated at 4.8V.

Tactic’s optional TACP1000 rechargeable battery and wall

charger kit includes eight “AA” size rechargeable NiMH cells
and 110V AC wall charger. It is compatible with this Tx and
can be found at local retailers. Make sure to follow the

instructions included with the charge kit.

WARNING!! It’s not recommended to charge
batteries at greater than 1 amp through this
charge jack. Fast charging of NiCd and

NiMH batteries should ONLY be done with
chargers that are specifi cally designed to include the
peak-detection function which can automatically stop
charge when full charge is detected. Misuse, improper
charging, or over-charging of rechargeable cells can
result in damage to the cells that could include cell
rupture, explosion, or fi re!!

CHARGE JACK

WARNING!! Do NOT attempt to recharge
alkaline batteries! The charge jack should
ONLY be used if rechargeable cells are used

The TTX404 includes a built-in charge jack for convenient

recharging of NiCd or NiMH batteries, and is compatible
with charge leads designed for Futaba® brand transmitters.
(HCAP0101) This jack is NOT compatible with charge leads for
Hitec®, Airtronics®, JR® or Spektrum® radios. The compatible
charge plug is shown in the picture below.

The TTX404 Tx includes a built-in wireless trainer function
– no trainer cable required! This trainer system connects a

teacher’s Tactic Tx to a student’s Tactic Tx by wireless
connection. Tactic’s wireless trainer function is not compatible
with trainer systems in any other brand radios.

IMPORTANT! Before attempting to fly the

airplane, it’s very important to make sure all

reversing switches and trim lever adjustments

on the student’s Tx match the settings on the
teacher’s Tx! Otherwise, the airplane could suddenly veer
off in an unwanted manner when the teacher’s trainer switch

is pressed. Proper matching of the student and teacher’s Tx
settings should ensure that no unexpected movements occur
when the trainer switch is pressed. This is especially true of
the throttle control!

1. The Tx that was used to setup the controls on the aircraft
must be used by the TEACHER.

2. The student must use a separate Tactic Tx with wireless
trainer function.

3. Place the teacher and student’s transmitters within 1
meter of each other, and make sure the throttle stick
for each Tx is set to idle.

To use the charge jack with optional rechargeable batteries,

fi rst remove the sticker that covers the charge jack on the

4. Turn ON the power switch for the Tx being held by the
student.

5. Pull and hold the trainer switch on the teacher’s Tx, and
then turn ON the teacher’s Tx power switch.

19

6. The LED on the teacher’s Tx will fl ash 3 times to indicate
it has become bound with the student’s Tx.

7. The teacher can then release his trainer switch.

8. Once both transmitters are bound together, power can
be applied to the receiver to prepare for fl ight.

When the training session has ended, with the model on the
ground and all power removed from the model, place both
transmitters within 1 meter of each other and simply turn the
power switch for both transmitters to the OFF position. This
will terminate the wireless link between both transmitters. If
additional training will be performed again, return to step 1
above to re-establish the wireless link between the teacher
and student’s transmitters.

TR624 RECEIVER & FLIGHT
EQUIPMENT INSTALLATION

(if applicable)

BIND THE RECEIVER

TO THE TRANSMITTER

For proper operation it’s necessary to “bind” the Tx and Rx
together electronically. This ensures sole communication

between the two, and prevents other transmitters from being

able to control the receiver.

1. Turn on the Tx.

2. Apply power to the Rx.

3. If the Rx LED fl ashes once and then stays on, the
Rx is already bound to the Tx and you can skip to
the next section. Otherwise, insert a small diameter
screwdriver through the hole marked “BIND” and press
the pushbutton until the Rx LED glows red and then
turns off after about one second.

4. Release the “BIND” button.

5. If the binding is successful, the Rx LED will fl ash once
and then remain ON.

RECEIVER (Rx)

Mount the receiver as specifi ed in the model’s instructions.
It’s important to keep the Rx as far away from the engine/
motor, servos, and ESC and other electronic items as possible.

To prevent the Rx from becoming damaged, it might be

acceptable to mount it inside certain models using Velcro®. In
certain cases, wrapping the Rx with foam rubber can help to
prevent damage from occurring due to vibration, but foam
rubber can prevent adequate airfl ow from passing over the
receiver in warm environments which might not be
recommended. Additional Tactic TR624 receivers can be
purchased from your local retailer (part number TACL0624)
to work with this TTX404 transmitter.

IMPORTANT! Always make sure that power
is applied to the transmitter BEFORE applying
power to the receiver and servos, and that

the throttle stick is at minimum (idle) position.
Failure to do so could result in the model becoming
uncontrollable and cause a safety hazard.

6. Test for proper Tx/ Rx functionality in the next section.
If the radio doesn’t appear to have become properly
binded, repeat steps 1– 6 above.

FAILSAFE FUNCTION

The included TR624 receiver has a failsafe feature which

engages in the event that the radio signal from the transmitter
somehow becomes interrupted. This safety feature causes the
servos to automatically move either to a certain position, or hold
their last position so to prevent the model from moving in an
erratic manner. Channels 1, 2, and 4 will enter a “hold” mode,
whereby the servos will lock in their last recognized position.

The servo connected to channel 3, normally being the throttle

control, will move to a pre-set position. The factory default
failsafe position for channel 3 is to move to 0% full throttle.
Motor/prop movement should stop if the receiver loses signal
from the transmitter. The throttle servo’s failsafe position can

be manually re-set to any other position if desired, as follows:

IMPORTANT NOTE: Before manually resetting the failsafe,
make sure the servo reversing switches are in the correct

position for the application.

1. Apply power to the Tx and Rx.

2a. If using an ESC, do NOT arm the ESC. Do NOT attempt

to adjust the throttle’s failsafe position if the ESC is armed.

2b. If using a gas or glow powered engine, do NOT attempt

to adjust the throttle’s failsafe position while the engine
is operating.

20

3. Move the Tx throttle stick to the desired position for the
throttle control to move if the Rx goes to failsafe.

4. Press and hold the “Bind” button on the receiver, and the
Rx’s LED should blink twice. Release the Bind button,
and the receiver’s LED should turn on (stop fl ashing).

The Tx and Rx should now be bound, with the throttle

failsafe in the new position as set above.

NOTE: If you’re using an ESC which has a signal loss feature,
the pre-set failsafe position is irrelevant as the signal loss feature
will cease the throttle operation if the signal is lost.

SYSTEM CHECK AND OPERATION

WARNING! During all pre-fl ight preparations with
the aircraft on the ground, make sure the throttle
stick remains at the minimum position and do

not stand the Tx upright on the ground. Carefully
lay the Tx on its back on the ground to prevent it from falling
over and possibly dislodging the throttle stick from the low
position which would create a safety hazard. Make sure all
devices are properly mounted inside the model, and all wiring
connections are solid to prevent them from easily becoming
dislodged during normal fl ight. It’s best to check the system
with the propeller removed from the aircraft.

1. Once all connections are made, check the general
operation of the radio and all other components before
attempting a fl ight.

2. Move the Tx throttle stick to the minimum (idle) position.

3. Turn on the Tx, and then the Rx.

b. Glow: confi rm that when the throttle stick is at

maximum position the mechanical linkage to the
engine allows the engine to be at full throttle. And,
when the throttle stick is at minimum position and
the throttle trim lever is moved to minimum position,
the engine stops completely.

7. Perform a “range check.” The “range” is the safe
operating distance from the Tx to the Rx, and should
be as far as you can clearly see the model. With the
assistance of another person, place the aircraft on the
ground and walk 100 feet (30m) away from the model.
With the Tx pointed directly at the model, operate
the transmitter’s controls, and ensure the movement
of all surfaces is according to the movement of the
transmitter.

8. Anytime power is to be removed from the radio system,
it’s important to shut down power in the aircraft fi rst.
Otherwise, the aircraft could become out of control
and cause a safety hazard! Move the throttle stick and
throttle trim lever to minimum position to stop the glow
engine or shut down the ESC. Once the propeller has
stopped rotating, shut off the ON/OFF power switch
in the model, and disconnect the power battery from
the ESC in electric airplanes. Then turn off the power
switch in the Tx.

4. Make sure all controls are operating in the proper
direction. If any servo is turning in the wrong direction,
change the position of the reversing switch for that
particular channel.

5. With both sticks at center position, move the trim levers
for the aileron, elevator, and rudder channels so each
respective control surface is perfectly aligned with the
main surface. For example: When the aileron trim lever
is in the center position, it’s best that the trailing edge of
the aileron is aligned with the trailing edge of the wing
itself (not above or below the wing’s trailing edge).

6. Make sure that movements of the throttle stick result
in an equal adjustment of the throttle in the model.
Depending on whether the airplane is electric or glow
powered:

a. Electric: confi rm that when the throttle stick is at

maximum position the electronic speed control gives
the appropriate indications (LED and/or audible
indicators) for full forward fl ight. And, when the throttle
stick is at minimum position the electronic speed
control gives the appropriate indications for “off” or
no motor rotation.

IMPORTANT WARNINGS

AND PRECAUTIONS

● NEVER allow water or moisture to make
contact with the electronic components inside the
transmitter, receiver, servos, switch harness, etc.!

This could lead to failure or improper functionality
of components and poor control of aircraft which could
pose a safety hazard.

● NEVER operate R/C model aircraft near power lines, radio
or cell phone towers, roads or automobiles, buildings, or
pedestrians. Be very careful in locations where many R/C
aircraft are being used simultaneously.

● NEVER operate R/C equipment if you are physically
impaired as it could pose a safety hazard to yourself or
others in the area.

● NEVER allow small children to operate/control model R/C

equipment without the supervision of an adult.

● NEVER allow the transmitter’s throttle stick to accidentally

be moved away from the “off” or minimum position while
the model’s engine/motor is moving.

● ALWAYS range check the radio system before use.

● ALWAYS make sure that all transmitter stick movements

operate all servos properly in the model. Check the proper
operation of control surfaces before and after starting the
engine/motor.

● Do not store your radio equipment in extremely hot or
cold locations, in direct sunlight, or in locations with high
humidity. Store R/C equipment in cool and dry locations.

● Do not allow chemicals to come in contact with any parts of
the radio system. Substances such as glow fuel, gasoline,
CA glue, etc. could permanently damage plastic parts of
the radio system.

● If NiCd batteries were installed in the transmitter, remove
the batteries before placing the radio in long-term storage.

TROUBLESHOOTING

RANGE IS SHORT

Interference – check Rx installation and servo connections.
Low Tx or Rx battery – replace the batteries or recharge if
applicable. Rx may need to be located to a different position
in the model for better reception. Crash damage – send the
radio to Hobby Services for repair.

RUN TIME IS SHORT

Low Tx or Rx batteries – replace or recharge the batteries.
Obstructed servo linkages causing excess battery drain –
free the linkages / pushrods.

Tx POWER SWITCH ON BUT SERVOS DO NOT FUNCTION

Tx or Rx batteries are low – replace or recharge the batteries.

Rx switch is in the off position – turn on the ESC or switch
harness. Switch harness or ESC is connected incorrectly –
check all connections and the ESC instruction manual. Rx
is not binded to the Tx properly – perform binding process
again. Check Tx or Rx battery polarity.

INTERFERENCE OR SERVOS GLITCHING

Out of range – operate the model more closely to the transmitter.
Outside radio interference from pagers, strong industrial or
other commercial transmitters in the area - check your local
R/C club regarding local operation. Rx located too closely to
engine, motor, or servos or other moving mechanical parts
which might be creating unwanted electrical noise – relocate
the Rx inside the model or relocate the ESC.

CONTROL SURFACE MOVES IN THE WRONG DIRECTION

Reverse the position of the reversing switch for the
appropriate channel.

ONLY ONE SERVO GLITCHES

Servo is bad – replace the servo or send to Hobby Services
for repair.
