INTRODUCTION

Congratulations and thank you for purchasing the Tower

Hobbies Sbach EP. While the Sbach is primarily an aerobatic,

3D-type of plane, its contemporary and sleek lines make

it appealing to all kinds of pilots, both intermediate and

advanced. The Sbach can serve all as its light wing-loading

and large control surfaces make it an aerobatic machine,

while its long moments and large ying surfaces make it a

smooth-ying, everyday sport model, too.

For the latest technical updates or manual corrections, nd the

Sbach EP on the Tower Hobbies web site at www.towerhobbies.

com. If there is new technical information or changes to this

model a “tech notice” box will appear on the page.

ADDITIONAL ITEMS REQUIRED

Radio/Servos

A minimum 4-channel radio with four mini servos and 4 –

5-channel receiver are required to y the Sbach:

❍Futaba R617FS 7-channel FASST receiver (FUTL7627)

The Sbach is intended to be own with mini servos in the 20g

range such as Futaba S3150 or Futaba S3172SV mini servos.

❍(4) Futaba S3150 digital servos (FUTM0303)

(4) Futaba S3172SV mini servos (FUTM0125)

❍(4) 6" [150mm] servo extensions are required for the

ailerons (one on each servo and one in each channel

in the receiver).

❍(4) Tactic servo extensions for Futaba (TACM2090)

(4) Tactic servo extensions Universal (TACM2092)

Brushless Electric Motor

The electric setup for the Sbach is straightforward: a

Great Planes Electrifly Rimfire .32 on a 13 x 8 E or 14 x

7E prop with a 75A ESC powered by a 4S 3800mAh LiPo.

A Castle Creations Edge Lite 75 ESC* is illustrated in the

instruction manual.

❍RimFire .32 42-50-800 (GPMG4700)

❍APC 13 x 8 thin E prop (APCQ3080)

APC 14 x 7 thin E prop (APCQ4045)

❍Castle Creations Edge Lite 75 ESC (CSEM1200)

❍3300mAh – 4000mAh 4S LiPo:

FlightPower 4S 3300mAh 25C (FPWP2334)

FlightPower 4S 3600mAh 50C (FPWP5364)

FlightPower 4S 3800mAh 30C (FPWP3384)

* If setting the BEC voltage in the Castle Creations Edge Lite 75 ESC

higher than the factory default 5.0V, it is recommended to use a

separate BEC regulator such as the Castle Creations 10A BEC

regulator (CSEM0005) to power the radio system on-board the aircraft.

LiPo Battery Charger

To charge a 4S 3800mAh LiPo at 1C, a charger capable of

about 65 Watts output power is required (4S x 4.2V/cell =

16.8V x 3.8A = 63 Watts). The Triton EQ2 (GPMM3156) is

more than enough charger with 100W output AC and 120W

output DC.

Adhesives, Hardware &

Other Accessories

Other than common hobby tools here is a list of the rest of

the items required:

A covering iron with a cover sock may be required for

tightening and re bonding covering to the model that may

have loosened between the time the plane was manufactured

and the time the model was removed from the box. The 21st

Century iron is preferred because of its long cord, contoured

shoe and precisely adjustable temperature range:

CANOPY REMOVAL/INSTALLATION

The canopy hatch is held in place with tabs in the back and

springs over dowels in the front. To remove the canopy, push

forward to disengage the tabs, then lift the rear up and pull

the canopy back and out to disengage the dowels. (If you feel

too much pressure is required to push the canopy forward,

the tabs could be shortened slightly to shorten the “throw”

that the canopy has to be pushed.)

PREPARATION

Between the time the covering was applied to your model

and the time it arrives in your hands it is normal for the

covering to loosen and wrinkle – especially if it has been a

long time and/or the air is dry at your location (causing the

structure to contract and the covering to loosen). But this is

easy to x using the proper tools and techniques.

The best way to renew the covering job is with a covering

iron with a protective cover sock not only to tighten the

covering, but also to thoroughly bond the covering to the

wood underneath. The preferred tool is a 21st Century cover

iron with a cover sock set to about 300°F [150°C]. This

translates to about 280°F [140°C] measured on the surface

of the cover sock.

Begin with the wings. You may also do the fuselage and tail

surfaces now, or wait until they are needed for assembly later.

❏1. Over unsupported covering, glide the iron across, but

where the lm is over structure apply pressure to bond the

covering down. Adjust the heat setting as necessary so the

covering tightens, shrinks and bonds to the wood, but not

so hot as to cause seams to pull apart.

❏2. Where possible, support the structure underneath with

your free hand to prevent the sheeting from bending inward.

❏3. OPTIONAL: When you get to the ailerons, elevators

and rudder, puncture three or four pinholes through the

covering on the bottom of those surfaces between each

of the braces or “ribs.” This will allow heated, expanding

air to escape so the covering will tighten. These pinholes

may appear obtrusive at rst, but when the covering is

heated the pinholes virtually disappear. Heat the side of the

covering without the pinholes rst.

❏4. Stack a few paper towels on top of each other and cut

them into small squares. These small paper towel squares

come in handy for dabbing up excess CA or wiping up

epoxy when dampened with denatured alcohol.

❏5. NOTE: All machine-thread screws that thread into

metal (hex nuts, blind nuts, wheel collars, etc.) should

be lightly wetted with threadlocker.

❏6. NOTE: The procedure for preparing the holes in

wood for all wood screws is as follows:

A. Drill the hole with the drill specied in the step.

B. Install, then remove the screw to form “threads” in

the hole.

C. Add a drop or two of thin CA to harden the hole.

D. Allow the CA to harden, then install the screw(s)

with the hardware that is being mounted/installed/

attached (servos, control horns, etc.).

ASSEMBLE THE WING

Hook up the Ailerons

Refer to this image while hooking up the aileron.

S3171SV

S3171SV #49 [.073"]

Drill

5/8" [16mm]

90°

❏1.

Connect the aileron servo to your radio so you can power

the servo. Position the servo arm so it will be perpendicular

to the servo, then cut off the unused arms. Drill out the holes

in the arm with a #49 (.073") drill.

Horn all the way to

leading edge of aileron.

90° Pushrod Connector

1/16"

[1.6mm]

❏2. Hook up the aileron with the hardware shown; note

that the aileron horn is mounted all the way to the forward

edge of the aileron. Using care not to drill through the top

of the aileron, drill 1/16" [1.6mm] holes for the servo and

horn mounting screws. Don’t forget to temporarily remove

the screws and harden the holes with thin CA. Connect

the pushrod to a hole about 5/8" [16mm] out on the servo

arm and the middle hole in the aileron horn. This geometry

should provide the correct 3D throw with the transmitter

servo end points dialed to about 110%.

3. Prepare the other wing with the aileron servo the

same way.

❏4. Use 6 or 30-minute epoxy to glue the nylon alignment

pins into both wings with approximately 1/4" [6mm]

protruding from the wing.

❏5. Test-t, but do not glue the berglass wing tabs into

the ends of the wings.

❏6. Fit the wings to the fuselage with the wing tube. Make

sure the tabs insert into the fuselage and the holes in the

tabs align with the holes in the brackets for the tab screws

in the fuselage. Make any adjustments necessary.

7. Remove the wings and tabs. Use 30-minute epoxy to glue

the tabs into the ends of the wing and wipe away excess

epoxy. Before the epoxy hardens, reinstall the wings back

onto the fuselage and position the tabs so the slotted holes

will be centered over the holes in the brackets. Momentarily

remove the wings to be sure there is no excess epoxy

around the tabs that would inadvertently stick the wing to

the fuselage. Reinstall the wings and immediately proceed

to the next step.

❏8. Before the epoxy has hardened, fasten the tabs

with an M3 x 10 SHCS (socket-head cap screw) and M3

lock washers and at washers. Push the wings snugly to

the fuselage and allow the epoxy to fully harden before

removing the wings.

ASSEMBLE THE FUSELAGE

Installl the Horizontal Stabilizer

❏1. If you haven’t yet done so, tighten the covering over

the fuselage and the tail surfaces. Be certain to seal the

bottom fuselage covering to the front of the former so the

covering cannot pull away.

❏2. Test-t the elevators to the stabilizer with the hinges

and the joiner wire—you may insert T-pins through the

middle of any hinges that don’t remain centered.

❏3. View the elevators from whatever perspective

necessary to see that they are aligned with each other. If

necessary, remove the joiner and lightly “tweak” with pliers

to align the elevators.

❏4. Temporarily mount the elevator servo, then remove

it (it’s easier to drill the holes for the elevator servo now,

before the stab has been glued in).

❏5. Mount the wings to the fuselage. Slide the horizontal

stabilizer into position. View the model from the rear to see

if the stab is parallel with the wing.

❏6. If necessary, remove the stab and carefully sand the

stab saddle where necessary to align the stab with the wing.

❏7. Now that the stab is level with the wing, center the

stab laterally by using a ruler to equalize the distance from

both ends of the stab to the fuselage.

❏8. Once centered, stick T-pins into the trailing edge of

the stab on both sides of the fuselage to lock the trailing

edge into place.

❏9. Tie a loop around one end of an approximately 48"

[1200mm] non-elastic line. Fold a piece of masking tape

over the other end of the line. Mark a line on the tape.

❏10. Insert a pin into the middle of the fuselage crutch

across the top of the former as shown. Loop the line over

the pin.

❏11. Hold the line with the tape to one corner of the stab.

Swing the line over to the corner on the other end of the

stab. Adjust the stab and slide the tape along the line until

the stab is centered and equalized.

❏12. Once you’re satised with stab alignment, use a

ne-point felt-tip pen to mark the outline of the fuselage all

the way around both sides of the horizontal stabilizer. Even

though the ink and most of the covering on top of the stab

are black, you’ll still be able to see the line indicating where

the covering will be cut and removed in the next step.

❏13. Cut the covering 1/32" [1mm] inside the lines you

marked around the stab. A hobby knife may be used if

the blade is brand new and sharp so little pressure will be

required for cutting, but extreme care must be used to cut

only through the covering and not into the sheeting

otherwise, the stab will be weakened. The best way is with

a soldering iron with a cutting-type of tip. A heat setting of

about 500F [260C] seems to work well.

❏14. Wipe away any residual ink with a paper towel square

dampened with denatured alcohol, then peel the covering

from the stab.

Glue in the Horizontal Stabilizer

❏1. Gather your small paper towel squares and denatured

alcohol for epoxy clean up. Small balsa sticks chopped

up from 1/16" [1.5mm] balsa sheet are also handy for

“squeegeeing” away most of the epoxy before using the

paper towel squares.

❏2. Don’t forget to place the elevator joiner wire into the

fuselage. It can be held out of the way with a rubber band

as shown in following images.

CAUTION: Have everything ready and on-hand for gluing

in the stab. Work quickly and efciently because some

30-minute epoxies may harden faster than others and

time ies when trying to work with precision—you don’t

want the epoxy hardening up before you have the stab

accurately aligned. ❏3. Mix up approximately 1/4 oz. of 30-minute epoxy.

Apply epoxy all the way around the stab saddle on both

sides of the fuselage and to the top and bottom of the stab.

❏4. Slide the stab into position. Wipe away excess epoxy

with the balsa sticks and paper towel squares dampened

with denatured alcohol. Double-check alignment, place any

weight on the stab if required for alignment and allow the

epoxy to harden before proceeding.
