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.
PROTECT YOUR MODEL, YOURSELF
& OTHERS… FOLLOW THESE
IMPORTANT SAFETY PRECAUTIONS
1. Your Switch Trainer EP 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 Switch Trainer EP, if not assembled and
operated correctly, could possibly cause injury to yourself or
spectators and damage to property.
Thank you for purchasing the Switch Trainer EP! The Switch
Trainer is a revolutionary new concept in R/C airplane fl ight.
Learn to fl y with the Switch Trainer high wing confi guration,
then move the wings to the low wing confi guration for exciting
aerobatic fl ight, with the same plane! In addition to getting two
airplanes in one, the model is made from durable AeroCell™
foam. Should the model become damaged, it is easily repairable
with epoxy or regular CA glue.
For the latest technical updates or manual corrections to the
Switch Trainer EP visit the Hobbico web site at www.hobbico.
com. Open the “Airplanes” link, then select the Switch Trainer
EP. 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.
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.
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.
2
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.

ASSEMBLE THE MODEL
Install the Landing Gear
2. Install a 2.5× 6mm self-tapping screw into the remaining
❏
holes in the pants and securely tighten them.
1. Thread a 2×12mm machine screw through the bottom
❏
hole of the landing gear leg and into the bottom hole of the
wheel pant. Insert the wheel into the wheel pant with the
hexagonal part of the axle to the inside of the pant. Thread
the 2×12 mm screw into the axle and securely tighten it, but
take care not to over-tighten the screws. There are left
and right wheel pants and left and right landing gear legs.
Assemble the gear according to the photos.
3. Fit the landing gear legs into the fuselage. Securely
❏
tighten the four 3× 8mm machine screws through the landing
gear legs and into the plywood landing gear mounting plate.
5
Install the Tail Section
1. Insert the horizontal stabilizer joiner rod into the pocket
❏
in the right stabilizer half.
4. Insert the elevator pushrod into the adjustable clevis
❏
on the elevator control horn as shown.
2. Fit the right stabilizer half to the fuselage by sliding
❏
the joiner rod through the hole in the stabilizer mounting
plate. The magnets installed in the stabilizer half will hold it
in place.
3. Install the left horizontal stabilizer half onto the joiner
❏
rod in the same manner. The elevator joiner rod must also
fi t into the tube that is glued on the underside of the left
elevator half.
5. If necessary, rotate the elevator and rudder servo arms
❏
so they are perpendicular to the pushrods. Set the elevators
in the neutral position by adjusting the elevator pushrod in
the adjustable clevis. When satisfi ed, tighten the screw in the
adjustable clevis taking care not to o ver-tighten it.
6
6. Insert the rudder pushrod into the adjustable clevis on
❏
the rudder control horn and set the rudder to the neutral
position in the same manner as you did the elevators. Tighten
the screw in the adjustable clevis. Do not over-tighten.
Setting Up the High Wing Confi guration
We recommend fl ying the Switch Trainer EP fi rst in the high
wing confi guration. The high wing position will provide some
self-recovery characteristics which will aid the beginning pilot
with straight and level fl ight. It will also make the orientation
of the airplane more visible at high altitudes.
3. Install the other wing panel in the same manner.
❏
Press the panels together against the hatch to ensure they
are fully seated.
4. Connect the included Y-harness to the aileron
❏
servo leads.
1. Slide the carbon wing joiner through the tube in the
❏
high wing canopy hatch and center its position.
2. 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 canopy hatch. Press the joiner tube into the
wing until the magnet “clicks” into place.
5. Connect the Y-harness to channel 1 of the receiver.
❏
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 bolt. Note: The wing bolt
must always be installed and tightened every fl ight!
Forgetting this step will result in a very short fl ight.
7
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.
4. Tighten the spinner cone onto the assembly using the
❏
included screw.
2. Fit the prop adapter onto the motor shaft, aligning one
❏
of the set screws in the adapter with the fl at spot on the motor
shaft. Tighten the set screws onto the motor shaft using the
included 1.5mm allen key.
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.
5. You have now completed the assembly of the high
❏
wing confi guration of the Switch Trainer EP!
CHANGING TO THE LOW WING
CONFIGURATION
When you have mastered the high wing confi guration and
are ready for a more aerobatic fl ight experience, then it’s
time to convert your Switch Trainer EP into the low wing
confi guration. The low wing confi guration will be more agile
in the air, roll more axially, and perform inverted fl ight with
ease as well as many aerobatic maneuvers not possible
with a high wing model. The low wing confi guration will NOT,
however, possess any of the self-recovery characteristics of
the high wing confi guration. We strongly suggest climbing to
a high altitude after takeoff with the low wing confi guration
for your fi rst few fl ights to become accustomed to the
differences between the wing positions.
1. Remove the wing panels from the high wing
❏
confi guration canopy hatch by disconnecting the aileron
Y-harness and sliding the panels off of the joiner tube.
8
2. Remove the screws that secure the aileron servo arms.
❏
Pull the servo arms off the servos and move the pushrod
wires to the outer holes of the arms (toward the wing tips).
Reinstall the arms onto the servos and replace the screws.
4. Insert the wing joiner tube through the joiner tube
❏
holes in the fuselage.
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.
3. Repeat this procedure for the pushrod wires connected
❏
to the elevator and rudder servo arms.
6. Connect the Y-harness to the aileron servo leads
❏
and also to channel 1 of the receiver. Test fi t the low wing
confi guration canopy hatch to the fuselage and bolt 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.

GET THE MODEL READY TO FLY
Lithium Battery Handling & Usage
Prepare the Transmitter
and LiPo Battery
1. Install fresh AA batteries into the transmitter. Follow
❏
the diagram molded inside the battery compartment.
2. Familiarize yourself with the charging procedure of the
❏
included LiPo battery. Read the charger manual completely.
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!
●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.
● 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.
3. Fully charge the LiPo battery.
❏
4. Install the included soft side of the hook and loop
❏
material to your battery pack. Test fi t the battery in the
airplane. When it is time to balance the model, you may need
to shift the battery forward or aft to achieve the balance point
provided later in the manual.
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 a continuous beeping sound, the throttle
channel needs to be reversed on the transmitter, following
Step 2. If not, skip Step 2.
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.

5. Moving the aileron control to the right (right stick)
❏
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.
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.
4. Moving the elevator control down (right stick) should
❏
cause the elevator to move up. Flip the elevator reversing
switch on the transmitter if necessary.
6. If you have not yet done so, set all of your trim levers
❏
to the neutral position. Confi rm that all of the control surfaces
are still in the neutral position. Confi rm that the servo arms
are still perpendicular to the pushrods as shown. If necessary,
remove the servo arm screws, adjust the positions of the servo
arms on the servos and replace the screws. Make any fi nal
adjustments to the control surfaces by moving the pushrods
forward or aft in the adjustable clevises (be sure to re-tighten
the clevis screws if you make adjustments). The procedure
for centering the ailerons is done in the same manner.
7. 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.
11
The following are excerpts from the SuperTigre® 30A ESC
manual that are necessary for operating the ESC. The
complete manual can be viewed online at http://manuals.
hobbico.com/sup/supm1020-1030-manual.pdf
NECESSARY TRANSMITTER SETTINGS
For proper ESC operation, 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.
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.
CONNECTING THE BATTERY
IMPORTANT! REMOVE THE PROPELLER FROM THE
MOTOR BEFORE CONNECTING THE BATTERY!
WARNING! Never accidentally short together the positive
(+) and negative (-) battery connections! Doing so will
result in permanent damage.
SuperTigre ESCs have a unique “ST” type polarized
battery connector as shown here, which is custommatched to the connector on SuperTigre LiPo batteries.
These plugs are polarized and cannot accidentally be
connected backwards. SuperTigre offers several sizes of
LiPo batteries to suit various needs, which can be found at
most hobby retailers:
SUPP1010 640mAh 11.1V LiPo
SUPP1020 910mAh 11.1V LiPo
SUPP1030 1250mAh 11.1V LiPo
SUPP1050 1500mAh 11.1V LiPo
SUPP1060 1800mAh 11.1V LiPo
(*Used on this plane)
SUPP1070 2100mAh 11.1V LiPo
To adapt your SuperTigre ESC to batteries having different
types of connectors, see your local retailer for these
SuperTigre adapters to meet your needs:
SUPM0040 Adapter - Deans® Ultra® Male to
SuperTigre ESC
SUPM0050 Adapter - Deans Micro to
SuperTigre ESC
SUPM0060 Adapter - Standard Female to
SuperTigre ESC
IMPORTANT! The battery must be fully charged
BEFORE being connected to the ESC. The ESC will then
automatically set the low voltage cut-off point based on
the INITIAL voltage of the battery multiplied by 0.67. So,
if the battery is NOT fully charged when connected to the
ESC, the ESC may set a low voltage cut-off that is too
low, and may not be good for your battery. Make sure the
battery is fully charged prior to every use.
LOW VOLTAGE CUT-OFF: SuperTigre ESCs include
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.
SETTING UP THE BRAKE FUNCTION
SuperTigre ESCs include an adjustable brake function. To
keep the factory default brake setting of “off”, skip to the
next section. To turn the brake “on”:
1. With the transmitter power turned off, move the throttle
stick to full position.
2. Turn on the transmitter and connect the fully charged
battery to the ESC.
3. After 5 seconds the motor will beep twice.
4. Move the throttle stick to the minimum position. The
motor will beep twice.
5. Again move the throttle stick to full power. The motor
will beep twice to confi rm the brake is now “on”.
6. Move the throttle stick back to “off”. The motor will
now beep four times indicating the motor is “armed”,
and the motor WILL ROTATE anytime the throttle
stick is advanced.
Once the brake is set, it does not require resetting after
the ESC has been switched off.
If the brake had previously been turned on, but you wish
to turn the brake off, repeat the above process. This time
the motor will only beep once with each stick movement,
but will beep four times again at the end to indicate the
ESC is armed.
ARMING THE ESC & SAFE-START FUNCTION
If ready to apply power to the motor:
1. Turn the transmitter’s power on.
2. Move the throttle stick to the minimum or brake position
(towards you).
3. Connect a fully charged battery to the ESC. The motor
will beep to indicate the brake setting (once for off,
twice for on).
4. Move the throttle stick to full. The motor will again beep
once or twice to indicate the brake setting.
5. Move the throttle stick to “off” or “brake” and the
motor will beep four times. The ESC is now “armed”,
and the motor WILL ROTATE anytime the throttle
stick is advanced.
12
If the ESC does not operate properly or makes a
low pitched beeping sound following the above setup procedure, disconnect the battery from the ESC,
reverse the throttle setting on the transmitter and repeat
the ESC set-up.
SAFE-START: As a safety precaution to prevent the motor
from rotating when the battery is fi rst connected, you must
“arm” the ESC every time you connect the battery. The
propeller will NOT rotate until the ESC is armed. To arm the
ESC, move the throttle stick to full position, then back to “off”
(or “brake”). Now the motor will rotate anytime the throttle
stick is advanced away from the “off” position! Care
must be exercised when near the model’s propeller!
Check the Control Throws
The Switch Trainer EP RTF is setup from the factory
with the recommended control throws for the high wing
confi guration. If at any time you wish to return to the
default control throws, or if you simply want to confi rm the
throws, use the following measurements:
At this stage the model should be in ready-to-fly condition
with all of the components in place including the complete
radio system, battery, canopy hatch, etc. The following
procedure is the same for both the high wing and low
wing configurations.
NOTE: The throws are measured at the widest part of the
elevators, rudder and ailerons.
These are the recommended control surface throws:

Balance the Model (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.
1. Apply narrow (1/16" [2mm]) strips of tape 2-7/16"
❏
[62mm] 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). Apply
another pair of tape strips 3-1/2" [89mm] from the leading
edge of the wing panels.
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 within the tape lines you applied.
3. Shift your fi ngers forward or aft between the tape lines
❏
until the model balances level on your fi ngertips. If you cannot
balance the model between the tape lines, you will need to
shift the battery and/or receiver forward or aft within the
fuselage. If the tail continues to drop even with your fi ngers
all the way at the aft tape lines, the model is “tail heavy”. You
will need to move the battery pack and/or receiver forward. 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 battery pack and/or receiver forward.
13
4. If you found it necessary to move the battery or
❏
receiver, recheck the C.G. to confi rm the plane now balances
between the tape lines. Do not fl y a plane that has not
been properly balanced!
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.
Range Check
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.
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 16 and place it on
or inside your model.
Balance Propellers
● 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.
● The motor gets hot! Do not touch it during or right
after operation.
● Do not throw anything into the propeller of a
rotating motor.
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 A viation magazine, the AMA web site or
the Code that came with your AMA license.
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.
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.
14
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.
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.
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].
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.
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
❏
attached in the fuse. Simply stuffi ng them into place with
foam rubber is not suffi cient.
15
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.
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.
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.
Take it easy with the Switch Trainer EP 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.
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.
GOOD LUCK AND GREAT FLYING!
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
