HE K THE "UPDATES AND MODS SE TION" BEFORE STARTING THE BUILD
The following guide and instructions are suggestions on how to assemble this model.
Depending on your skill level, you may deviate from the procedures to accommodate
your own building preferences. T
his manual is for mechanical assembly and
installation of electronic components only. Additional documents are available for setup
and tuning of the Flight Control Board. If not using the Twisted Hobbys' Components,
some of the details may still apply, bu
t ultimately functionality will be the responsibility
of the builder. It is also assumed that the builder has some basic skills related to
soldering and computer radio programming. It should also be noted that the Motors
must all be the same and the ESC's
should be multirotor compatible, this Assembly
Manual assumes that you are using the power components recommended by Twisted
Hobbys.
Also needed to finish your build
:
•4x 3.5mm Male Bullets
•4x 3.5mm Female Bullets
•3x Props 9x4.7 CCW suggested)
•Battery Connector of choice
•12in of red wire similar in gage to ESC wires
•12in of black wire similar in gage to ESC wires
•6in of heat shrink tubing

Examine the kit contents. Make sure
everything arrived safely
Items are packaged in groups by assembly
process. Each bag has a label with what it
should contain
Three identical motors and multirotor
ESC's, one servo, a receiver and flight
control board are needed.
Items included with the motor in the
Twisted Hobbys' power set. Note -
Not all of
these items will be needed
If you are familiar with
building these type models,
some of the directions may
not apply. It is however
suggested that due to some
of the unique construction
techniques, some attention
be given to those areas of the
build. - ENJOY

Rev: 2013.11.05.v001b 10
Multirotor capable ESC's are needed. The
20Amp Twisted Hobbys' ESC's are what is
recommended for this Tri-Copter
Servo size is important. Either use the 65
Series Twisted Hobbys' servo, or one that is
the EXACT same size. The servo is an
integral part of the tail and fits precisely
Receiver Detail - use the Receiver
of choice,
the Twisted Hobbys' Crack Receiver is
shown above. Note the polarity of the pins
in relation to the diagram in the picture
This build will use the MultiWii SE v2.5
Flight Control FC) Board, available from
Twisted Hobbys, comes with the accessories
shown
Remove the booms and hardware from the
"Booms" Bag, set the hardware aside for
now. This hardware is used to mount the
motors to the booms in a later step
Remove the items fro the "Main Frame"
Bag. Initially the two large frame pieces
Top and Bottom Deck) and the 18 button
head screws is what will be needed

Rev: 2013.11.05.v001b 11
Peel off the protective coating from the Top
and Bottom Deck pieces
Paper removed and ready for assembly Lay the bottom Deck onto your work
surface and situate the Booms on top as
shown
Lay the Top Deck on next.
The next couple steps are for planning
the placement of the Electronics only.
Do not assemble things permanently at
this time
Loosely install the screws, start from the
nose and work towards the rear. If there are
any miss alignments slightly enlarge the
holes as needed with hobby knife. Threads
are delicate, use care to avoid damage
Laying out the ESC's as shown will allow
for mounting them inside the frame, but
will require that the ESC for the tail have
an extension

Rev: 2013.11.05.v001b 12
This build will show the ESC's mounted
internally. This provides for a nice clean
underside. Shown on the outside here for
general location purposes only
Remove the Bottom Deck and place the
ESC's in their approx position
. Lay ESCs in
side as shown in the approx position you
determined in the previous step
Locate the Misc Frame bag Take the two Short Spacers and the two
Long Spacers from the bag, remove the
protective coating
Mounting the ESC's, externally, approx as
shown will not require any mod
ifications to
any of the ESC leads
. Note how the position
of the ESCs allow for all the leads to match
up
Solder some male 3.5mm bullets onto the
ESC and matching female bullets to 6 or so
inches of wire as shown. Wire should be the
same gage as the wires of the ESC

Rev: 2013.11.05.v001b 13
Bundle all the Red wires to
gether as shown.
A short piece of shrink tubing can be used
to temporarily hold them in place. Insert
into the bullet and solder. Repeat for the
Black wires
Remove the short temporary pieces of
shrink tubing and install slightly longer
ones that will protect the solder joints as
shown. Note that a JST power tap was
added, this could be for lights if wanted
Lay everything back into the frame to verify
that all the wires reach
Install the Spacers into the slots on the Top
Deck, this will hold the ESC's in their
approx positions. Plug the extension into
the Tail Rotor ESC
Set the Bottom Deck in place. No screws
needed at this time. Take note of how all
the wires will be run
Trim the extension wires to match the
length of the other two ESC's

Rev: 2013.11.05.v001b 14
Remove the ESC harness and the Spacers.
It is easier to do the next couple steps with
the ESC harness out of the way
Locate your Flight Control Board and
mounting hardware. Note if you don't yet
have a FC board, or will be installing with
stick foam, skip the next couple steps
Break off how ever many FC Spacers you
will need to space the board far enough
away from the mounting surface so there is
no contact
Under side of the Top Deck, Do Not Over
Tighten these screws, they should only
slightly compress the FC Grommets
For the MultiWii SE v2.5, you will need two
of the FC Spacers on each screw. The third
washer shown is the FC Grommet, a rubber
washer to help vibration dampening
Make sure the Arrow is facing forward

Rev: 2013.11.05.v001b 15
The USB Adapter is only used during initial
"flashing" of the board, and later for
adjusting the flight parameters, so it will
only be installed as needed for
programming and not be a permanent part
of the airframe
Lock the nuts in place with some glue.
Welders works well for this
From the Misc Frame bag, get the Canopy
Rails and remove the protective paper
Install as shown. Note that the forward
most and rearward most tabs will "snap"
into their locations slots
Check that the USB adapter will reach the
FTDI pins on the board. The adapter
included with the MultiWii SE v2.5 will not,
so a clearance hole or notch will be needed
Hole added with a motor tool for the USB
adapter. Note - this slot was added in later
releases of the model

Rev: 2013.11.05.v001b 16
View of the USB Adapter installed thru the
added hole
Now, flip the frame onto it's
back as shown,
both Canopy Rails should be installed at
this point. Space the frame off the work
surface with the motor boxes
Lay the ESC Harness back in place like it
was earlier
Find the Misc B ag Remove the Velcro Strap and the Long
Velcro Set
With a hole punch or hobby knife, make a
hole in the Velcro strip that will be attached
to the airframe, so that it clears the head of
the button head screw, see the next two
steps to help determine exact location

Rev: 2013.11.05.v001b 17
Double check that the hole is in the right
place and big enough to clear the screw
head
Stick down to the frame, between the slots
as shown
Feed the strap thru as shown. Middle slots
for sport flying.... rear slots for flying with
camera payload, mounted to the nose
Snap the Bottom Deck onto the tabs of the
Canopy Rails as shown
Install the screws to secure the Bottom
Deck. Loosely again, starting from the nose
and working back. Enlarge any holes as
necessary for alignment
Pull the Velcro strap tight

Rev: 2013.11.05.v001b 18
Locate the Front Legs from the Misc Frame
Bag and remove the protective paper
Legs point forward as shown
Slide the Leg on to the Boom Feed the wires thru the provided slot
Installing the Legs requires that the boom
pivots. Remove the outer most screws from
the Top Deck as shown
Remove the outer most screw from the
Bottom Deck

Rev: 2013.11.05.v001b 19
Continue sliding the Leg towards the Frame
Line up the slots in the Leg with the
material thickness of the Top and Bottom
Decks
Pivot the Boom slightly forward so that the
Leg can engage the front set of slots
Pivot the Boom towards the rear now so
that the Leg can engage the rear set of
slots. Once the front and rear slots are
engaged, center the Boom with it's mating
hole in the Bottom Deck
Install the screw to lock the Boom and Leg
in place
Repeat for the other side

Rev: 2013.11.05.v001b 20
Locate the Tail Bag and Rear Leg Bag Remov
e all the items from the Rear Leg Bag
and only the Pivot Shaft from the Tail Bag
as seen in the next two steps
Remove the protective paper. Notice the
orientation of the Side Plates and the
Spacer
Slide the Pivot Shaft into the opening in the
back of the Rear Boom. Note -
End with the
holes goes in first
It does not have to slide freely, but should
go in and out with only a slight amount of
pressure. Line the holes up with the slots.
Slots are used in a later step to adjust the
end play in the Tail Box
Loosely install the Side Plates as shown
