BEFORE YOU BEGIN
A word about laser cut parts and adhesives.
There are three primary types of adhesives recommended for constructing your model. They are CyanoAcrilate
(CA) in all viscosities, Aliphatic Resin Glue (carpenters glue) and Epoxy. CA is the primary adhesive to use
however there are times when it is not the best choice. They are;
When you need more time to carefully position a part then a fast setting adhesive will allow.1.
When attaching plastic such as a windshield (Use Pacer formula 560 here).2.
When gluing laser cut aircraft grade plywoods. The microwave set adhesives used in aircraft grade plywood3.
does not ablate well under a laser beam. As a result it burns the wood bers near by leav ing a charred edge. Fast
setting CA adhesives do not allow time for the adhesive to penetrate this layer of char and bond to the wood ber
underneath. Use a slower setting adhesive such as Aliphatic Resin or for maximum strength use Epoxy on aircraft
grade ply parts. Lite Ply’s do not use this type of adhesive and do not suffer from this problem.
To apply thin CA I recommend the Dave Brown pipets available at your hobby shop. Be sure to stretch the end
(pull it with a pair of pliers) to a thin applicator tip, as they are not supplied in this conguration and some folks
don’t know that you have to do this. No mention of this is made on the package they come in.
PIN REGISTRATION
A great shop technique introduced by Top Notch Products is the use of 1/8” piano wire pins to quickly and precisely
position laminated parts such as fuselage doublers etc. Many of the parts in Top Notch kits utilize this method
and are supplied with pinning holes. Take the time to construct two of these handy tools. Use two small hardwood
blocks and two short lengths of 1/8” music wire. Round the ends for easy insertion into the parts.
Below are two examples of this technique as used in the Cessna 195 kit. On the left, two re wall com ponents are
being assembled using the pins. Any time precision placement is required, this method is used. You will nd the
pinning holes are easily lled after completing the model. This method allows the use of fast setting adhesives such
as CA because the parts cannot be out of register. In the photo on the right, landing gear components are being
assembled with the pins. Precision placement of these parts is required to assure that the 1/8” landing gear wire will
t snugly into this assembly. In the background is the completed re wall assembly.
Use a sheet of Wax Paper to protect your plans. When assembling at sheets such as the stabilizer skins I recommend
laying the parts on a sheet of parchment paper. Assemble the parts, apply thin CA and frequently lift the part and
wipe up any excess CA from both the part and the paper with a piece of paper towel.

WING ASSEMBLY
BUILDING NOTE
Many of the wing components have dash cut stand off feet attached that will set the correct angle of all parts.
It is important that these stand off’s be at on the building board throughout the construction process. Check
periodically to make sure that is the case. After as sembly these will be snapped off and discarded.
£ 1Remove as needed all wing components from their carrier sheets and clean up any nubs left by the re-
tainer breaks.
£ 2Use the pin register method and assemble W3 and W3-A, make sure W3-A is on the outboard side.
£ 3Laminate Aileron Bay Liner (ABL) and ABL-B together. Be sure ABL-B is on the aileron or outside.
You will note that the notches for the ribs are in ABL and that must be on the inside.
£ 4Use a straight edge to align FLE with the wing drawing and tack glue pinning tabs (located on sheet 23)
to the stand off feet, then pin these tabs securly to the building board.
£ 5Locate section SW-A of the spar web and slide ribs W2 thorough W7 into the appropriate slots in the
spar web. Next slide the remaining spar web section SW-B down onto the ribs from the top. Tack glue
the spar webs together lightly at each end.
£ 6Locate tip spar web segment SW-C and install ribs W9, W10 and W11. Install tip spar segment SW-D
from the top similar to the root spar and tack glue the ends. You should now have the two spar webs with
all but the end ribs captive.
£ 7Install but do not glue all ribs into their appropriate notches in the false leading edge (FLE).
£ 8Install and Glue WGA to W3 and FLE. WGA will set FLE and W3 at a 90°
angle.
£ 9Test t CLE and bevel the top to conform with the rib contour. Then install CLE
to ribs W1, W2 and W3.
£ 10 Glue all ribs to FLE keep all ribs at 90°.
£ 11 Glue SWC and SWD assembly to the SWA and SWB assembly at W8, then glue
ABL & ABL-B assembly to ribs W8 through W12. Taper the tab at the end of
ABL to seat properly in the notch in W8.
£ 12 Glue all ribs to the spar web segments.
£ 13 Install the ABL assembly and glue to ribs W8 thorough W12, then install gus-
sets WGB and WGC.
£ 14 Assemble the 1/16” spar anges (SF) and install the top spar ange. The spar
ange must be in good contact with the sheer web and glued along the entire
length of the spar.
£ 15 Install top trailing edge sheet.
£ 16 Plane FLE and CLE to contour with the ribs. Locate and test t the 1/32” leading
edge sheeting, mark the spar ange at the root where the sheeting stops. Apply
a liberal bead of thick CA to the spar ange from this mark to the tip and then
install the top sheeting.
£ 17 Remove the wing from the plans and use thin CA to glue the sheeting to each rib and FLE.
£ 18 Install one section of top center section sheeting (CSS) and then measure, trim and install the second
CSS to ll the top center section.
£ 19 Remove all stand offs and pinning tabs. Clean up these areas with a light sanding.
£ 20 Taper slightly the trailing edge of the bottom trailing edge sheeting (TES) and glue in place.
£ 21 Glue the servo mount (SM) in place and then glue on the servo mount screw doublers.
£ 22 Glue on the bottom ply spar ange. Weight this assembly sufcient to assure good contact with the spar
web (SW) until cured.
Wing construction under way
with FLE tacked to the building
board with pinning tabs and the
ribs in place on SW-A, SWB and
SWD will be installed next.

3
£ 22 To glue on the bottom leading edge sheeting use the following sequence. Apply aliphatic resin glue to
all ribs between FLE and SW. Then apply medium or slow CA to the spar. Install the leading edge sheet
and hold it rmly against the spar until cured. Next using nger pressure, pull the leading edge sheeting
rmly against each rib to make good contact with FLE. Use thin CA to glue it to FLE. Proceed from the
center out toward to both end of the wing
£ 23 Install the 1/4” balsa leading edge and then add LEF at the root end.
£ 24 Laminate two 1/4” WT parts together to form the wing tip block and then glue in place.
£ 25 Assemble the remaining wing half by repeating steps 1 through 23.
£ 26 To assemble the wing halves cut two 1/2” pieces of 1/8” dowel and glue them into the holes in WJ.
These will serve to align the two wing panels. Glue WJ to one wing panel and then glue this assembly
to the remaining wing panel. Use Epoxy to glue SFJ to the spar anges on the top and bottom of the
wing. Note that WJ is cut 1/64” oversized to accommodate sanding out ush with the wing sheeting.
FINISHING THE WING
It is best to nish shaping the leading and trailing edges after the wing halves have been assembled. Do
not shape the wing tip trailing edges until you have completed the aileron assembly. Use LEF as a guide
to shaping the leading edge, also use the supplied leading edge template to check for the correct shape.
This work is best accomplished with a razor plane and a sanding bar. The tip block leading edge (WT)
can be formed at the same time as the leading edges. To nish forming the tip block, rst assemble the
ailerons. Tape them in place along the entire aileron leading edge and then align them with the wing
trailing edge at the root and tape them in place. Use the aileron tip to mark the wing tip block (WT) and
do the nal shaping of the wing tip block. Note that 3° of wash out is introduced into the outer wing panel
from W8 to the tip. Sand the trailing edge to a rounded contour.
AILERON ASSEMBLY
£ 1Locate and prepare the aileron base (AB). Install Al, note the Al must be canted in slightly, use the
aileron dihedral gauge (ADG) to set the correct angle.
£ 2Install and glue A2 through A5. Note that these must be at 90° to AB. A5 simulated the aileron counter
balance and must be parallel with the end of the aileron base.
£ 3Plane a slight bevel on the bottom of ALE to provide good contact with the aileron base, and then glue
it to the aileron base and the front of Al through A4.
£ 4Glue the aileron horn plate (AHP) to the aileron base where indicated.
£ 5Plane the top leading edge of ALE to contour with the ribs. The aileron will be attached to the wing
with aileron tape along the top leading edge after covering.
STABILIZER ASSEMBLY
Building note:
When installing the stabilizer parts onto the core sheet, make sure the parts are pressed at against the
bench. This is especially important for the leading and trailing edge installation. Remember that the
shape that the stabilizer is in when you apply glue is the shape it will retain.
£ 1Install all split ribs on one side of the stabilizer core sheet. Start with S-1 and proceed out in both di-
rections to the tip.
£ 2Install ETE trailing edge.
£ 3Install SD ply brace.

4
£ 6
£ 4Install leading edge (ELE) in the same manner as the trailing edge.
£ 5Flip the assembly over and install the remaining ribs.
Install the remaining trailing edge and leading edges.
£ 7Install the remaining ES ply brace.
£ 8Plane and sand out the leading and trailing edges to contour with the ribs.
£ 9Assemble the eight sections of 3/32” stabilizer sheeting (ES) to produce four assemblies. Select the best
side of each of these assemblies and sand them out smooth while still at. Sand the leading and trailing
edges of the stab assembly to contour with the ribs and then glue on each section of sheeting.
£ 10 Carefully remove that portion of S1 and the core sheet that is in line with the hole in the center sheeting.
This will allow pass through of the rudder horn shaft when installed.
ELEVATOR
£ 1The elevator core sheets are composed of a 1/16” balsa main section (EC) with a 1/16” ply trailing edge
section (ECTE). These must be assembled prior to building the elevators. The recommended method
is to place the parts together on a sheet of parchment paper (available in the baking department of your
grocery store). Keep a folded pad of paper towel handy, run a bead of thin CA along a section of the
joint between the two parts. Use the paper towel and a quick swipe to remove any excess glue. Lift the
assembly and wipe off any glue on the reverse side as well as the parchment paper. Repeat this process
until the core assembly is completed.
£ 2Assemble the elevator horn and joiner assembly.
£ 3Install El through E6.
£ 4Install EHD over the elevator horn slot.
£ 5Install ELE.
£ 6Flip the assembly over and install El through E6 and ELE.
£ 7Install ELE at the front of ribs E5 and E6.
£ 8Sand and shape the tip leading edge. Sand the leading edge
hinge line to approximately a 20° angle to allow clearance for
hinging.
£ 9Repeat for the second elevator. The elevator horn is silver soldered to the elevator
linkage rod. The rod is 1/16” M.W and the horn is
fabricated from 1/8” brass tubing.
£ 11 To assemble the elevator halves, rst locate a 12” piece of 1/4” scrap balsa. Sand the edge to make sure
it is perfectly straight. Pin this to the building board. Secure two 1” x 1/2” pieces of scrap 3/32” balsa
to use a shims. Test t the assembly by inserting the linkage rod into both elevator halves. Place the as-
sembly with the hinge line against the straight edge of the 1/4” scrap piece and place a 3/32” shim under
each leading edge at the E4 location. The shims will maintain a straight hinge line. When satised with
the assembly remove it, disassemble it and then use epoxy to secure the halves permanently. Be sure that
the leading edge rests on the building board at the center and on the 3/32” shims at the E4 location.
£ 10 Flatten a piece of 1/8” x 5/8” brass tube about 1/8” at both ends
at 90° to each other. Drill a 1/16” hole at one end for the push
rod clevis pin and then silver solder the opposite end to the stabilizer joiner. Note the off center position
at 90° to the bend as shown.

5
RUDDER ASSEMBLY
£ 1The rudder core sheet (RC) has a ply trailing edge (RTE) similar to the elevator core sheets. Assemble
the rudder core sheet.
£ 12 Cut two hinges in half lengthwise to produce four
1” x 3/8” hinges. Install these to the elevators and
stabilizer at the locations indicated on the plans.
Do not glue until after covering. This concludes
the stabilizer/elevator assembly.
RIGHT
The completed stabilizer and elevator assembly ready for cov eting
and then installation on to the fuselage assembly. Assure that the
hinges work freely and that the elevator counterbal ance protrusions
do not bind, allow for covering material.
£ 2Install R1 through R6.
£ 3Install the rudder leading edge RLE. Install R8 and R9.
£ 4Install the rudder horn caps RHC.
£ 5Sand or plane a 20° angle on the rudder leading edge for hinge clearance.
£ 6Cut a 5/8” length of 1/8” brass tube. Crush at about 3/16” at both ends. Drill a 1/16” hole in both ends
about 3/32” from the end. Bend the 1/16” M.W. rudder torque rod and slide the one end of the brass tube
onto the end of the torque rod. Solder in position at 90° to the bend. Do not install permanently in the
rudder until after covering.
VERTICAL FIN ASSEMBLY
£ 1Assemble the three n core sheet sections.
Use the same technique as you did on the
stabilizer core sheet assembly.
£ 2Install ribs V-1 through V6. Use a straight
edge to assure that V-1 is straight and at
90° to the core sheet. This will provide the
platform of the n that will attach to the
fuselage top and must be at.
Like the stabilizer and elevator assembles, the vertical n is built on a core sheet. Shown
here are the three sections of the vertical n core sheet ready to be assembled.

6
The vertical n trailing edge is positioned by setting the tab in VTE in
the notch on the core she . Then the trailing edge is glued to the
core sheet.
The vertical n assembly shown here with all internal components installed. The leading
and trailing edges must be sanded to the contour of the ribs and then the covering can
be applied to complete the structure.
£ 3Using a straight edge to assure straightness, install the vertical n trailing edge VTE. Note VTE will
extend beyond the bottom edge of the core sheet. This extension will become the rudder post.
£ 4Install VLE-3. Trim VLE-2 to t to VLE-3 and then install VLE-2. Trim VLE-1 to t to VLE-2 and then
install VLE-1.
£ 5Flip the assembly over and repeat this procedure to complete the vertical n.
£ 6Plane and sand the leading edge to shape.
£ 7Assemble the 1/32” vertical n sheeting from three sections. Select one side as the outside and sand
that side smooth while it is still at.
£ 8Note that the sheeting is positioned by two tabs in the trailing edge. Place one of the vertical n skins in
position and apply thin CA to all ribs, leading and trailing edges from the opposite side while forming
it to the ribs.
£ 9Install the remaining vertical n skin by applying aliphatic resin glue to all ribs. Then place the
remaining vertical n skin in position and apply thin CA along all leading and trailing edges.
£ 10 After curing, sand the vertical n leading edges to shape and then sand all surfaces smooth. Install the
rudder and put this assembly aside. The vertical n and rudder assembly is ready to cover.
FUSELAGE ASSEMBLY
Each fuselage side is supplied in three sections. The three main sections are the front, cabin and tail
or aft section. In addition there is a small piece that must be added to the cabin section at the front just
ahead of the wing seat. The 1/64” ply doublers are glued in place prior to assembling the three fuselage
sections. When assembled, the three fuselage sections will form a fuselage side that is angled at the front
and at the back. It is important that these angles are correct and exactly the same on both fuselage side
assemblies. Jig FFA (forward fuselage angle) and AFA (aft fuselage angle) are temporarily installed on
the outside of the front and back fuselage sections to assure the correct angle when assembling the three
fuselage sections.
£ 1Prepare the balsa fuselage sections for assembly. Glue on the small piece at the top forward part of the
center section.
£ 2Prepare the two 1/64” ply fuselage doubler sections for assembly.

7
ABIVE RIGHT The center fuselage section shown here be ing
assembled with the 1/64” ply doubler. The pinning meth od is used
here to assure perfect alignment of all notches. Additional holes
are provided to be used as glue ports. It is important that these ply
doublers be positioned accurately .
A streight edge is used to hold the the 1/64” ply doubler at and in
good contact with the balsa fuselage side. A liberal application of CA
is added and any excess removed with a paper towel.
See the text for more information on the process of gluing the
doubler to the fuselage side along the window openings and exterior
edges. Is is important that the doublers be se-curly bonded to the
fuselage sides.
BELOW:
Here a completed fuselage side with doublers installed is ready for
formers. Note the 1/32” balsa strip along the forward nger joint.
£ 3Precise placement of the fuselage doublers is critical,
use the pinning method described at the beginning of
this manual. Lay out all six fuselage sections on the
bench to create a left and a right side. Note that the
aft section has marking on it to locate the 1/8” x 3/16”
stiffeners. These markings must be on the inside of the
fuselage. Pair up the 1/64” ply fuselage doublers with
the fuselage sides. Place one of the balsa forward sec-
tions on the pins, then place the doubler on the pins
over the side. Force the two into contact and tack glue
with CA. Repeat this procedure for all four fuselage
doubler sections. Note that in the photo at the right,
the two 1/8” music wire pins have been mounted in a
small MDF block to simplify use of this method.
£ 4Turn this assembly over with the ply side down on a
piece of parchment paper. Use a straight edge to press
the parts at and apply a bead of thin CA along all edg-
es. The thin CA will wick into the balsa and ply along
the edges and bond the two securely. Have a piece of
paper towel handy and when necessary make a quick
swipe with it to clean up any excess CA glue. Occa-
sionally remove the assembly form the parchment pa-
per and wipe up any excess CA with the paper towel.
£ 5Repeat this process for the center section and the cen-
ter section ply doubler.
£ 6Place the center section on the bench with the doubler
side up. Use a straight edge or a piece of ridged wood
and weight to assure that the forward edge is at on
the plans.
£ 7Tack glue or pin FFF to the outside of the forward
section and then place the forward section in position
against the center section. FFF will set the correct angle
for the forward section. They should t tightly togeth-
er with no gaps. Glue along the entire joint between
the forward and center sections. Cut a piece of 1/32”
scrap balsa 1/4” wide and 5” long. Place this over the
hinge joint on the 1/64” ply and using a straight edge
to force it into contact with the ply, apply thin CA to
this joint. This concludes joining the forward and cen-
ter sections.

8
£ 8Use a piece of scrap 1/32” material to shim up the center section about one inch ahead of the nger joint
at the aft edge. This will allow the ngers from the aft section to better center on the center section n-
gers. Use a weight on top to hold the center section perfectly at. Install AFF into the aft section to set
the correct angle.
£ 9Press the aft section into position with the center sections until all the ngers are completely meshed.
Apply a generous bead of thin CA to this joint.
£ 10 Remove the assembly from the parchment paper and repeat for the other fuselage side. Be sure to make
a left and a right side.
£ 11 Install the 3/16” square stock along the top and bottom of the aft section. Then install the 1/8” x 3/16”
stiffeners.
£ 12 Install the 1/16” ply wing saddle (WS)
£ 13 Install the 1/4” lite ply wing mounting plate (WMP). Note prior to installing WMP, press in the #832
T-Nuts.
Fuselage side subassemblies ready to install the formers. All formers should be installed with the former labels facing forward. Here the three
fuselage sections have been assembled with the 1/64” ply doublers, wing saddle doubler, wing bolt plate and all balsa stiffeners in the aft
section.
£ 14 Use Epoxy to install F4 and F5 to one fuselage side. Make sure both formers are at 90° to the fuselage
center section.
£ 15 Install the other fuselage side to this assembly.
£ 16 Install F1, F2 and F3, note that the labeling side of these formers MUST face forward.
£ 20
£ 19
£ 17 Laminate LGM and LGM-A together. Use the pinning method to assure accurate alignment.
£ 18 Install the LGM assembly with Epoxy.
Install the two LGC’s. Note that the hole in LGM must align with the slot in LGC. If it does not, move
that LGC to the other side of the fuselage and use the remaining LGC.
Cut four 1-1/2” lengths of 1/8” x 1/4” basswood, glue these to the bottom of the servo tray along the
servo screw line. This will provide additional material for the screws to grip.

9
Looking back through the tail section of the
model you can see the square balsa added to
the fuselage sides as well as the top and bottom
for additional strength.
Forward section with corner sheeting installed
and ready for shaping. Note that this model is
being constructed with the glow rewall for use
with a glow engine.
A look inside the cabin section showing the servo tray on the right
and the landing gear mount on the left. The wing saddle doubler is
at the top and the wing mounting bracket and blind nut are on the
upper right.
This view shows the cabin and forward section of the fuselage. The landing
gear mount is on the right and the ply plate on the left is to support the aft
mount for oats if so desired. A oat kit is available for this model.
£ 21 Install the servo tray.
£ 22 Install stabilizer doubler STD.
£ 23 Install F6.
£ 24 Install BTC to the aft bottom of the fuselage.
£ 25 Install TGP.
£ 26 Install FLA.
£ 27 Glue a piece of 3/16” Sq. to the top back edge of F5. This will sup-
port the top sheeting.
£ 28 Glue a piece of 3/16” Sq. to the top front of F6.
£ 29 Assemble the aft deck (ATS) and install the 3/16” sq. Cross pieces.
Glue this assembly to the aft top fuselage.
£ 30 Install FCP, chamfer the edges to match formers Fl and F2.
£ 31 Assemble the aft bottom sheeting (ABS) and add the 3/16” brac-
ing where indicated, Glue this assembly to the aft bottom of the
fuselage.
£ 32 Install F-10 (2) between Fl and F2. Bevel both edges of F10.
Then install F11 at the bottom also between Fl and F2.
£ 33 Locate the berglass cowl and the ply cowl ring (CW). Place the
cowl with the spinner ring at against the bench and draw a line
all the way around it at exactly 3-1/2” from the bench top. This is
easiest if you use a stack of magazines or other object to hold your
pencil at at that elevation. Then rotate the cowl against the pencil
while holding it at against the bench. Trim the cowl on this line.
Use the template supplied to mark the cowl openings in the front of
the cowl and cut these openings. Glue the cowl ring into the back
of the cowl with Epoxy.
£ 34 Temporarily install the cowl and nish shaping the forward section
of the fuselage. Fair it in with the shape of the cowl.
£ 35 Add 1/4” triangle stock to the bottom of the fuselage sides between
FHP2-A and LGM-A.

10
£ 5
The rudder and elevator linkages are concealed inside the fuselage. It is important therefore that these assemblies
be carefully constructed and installed for long trouble free operation. If you do not wish to go to this trouble, you
can bring the control linkages out the side and top of the fuselage as you would on a sport model. If you are not
familiar with silver soldering techniques please see the Silver Soldering Primer on my web site under Shop Tips.
Use the following sequence to install the vertical n, stabilizer, rudder and elevator.
EMPENAGE INSTALLATION
£ 1Cover the stabilizer, elevator assembly, vertical n and rudder.
Bottom view of the tail section showing the bottom tail cap installed. The notch
and tab construction assures that the fuselage sides are aligned and parallel
to each other. No banana’s here. Below this is the stabilizer saddle.
Shown here the aft fuselage section is nearing completion with the stabilizer
saddle on the right. The cabin area and tail cone are cavernous with plenty of
room to work and space for gear.
£ 2Install the hinges on the stabilizer and eleva-
tors.
£ 3Assemble the linkages for the rudder and el-
evator. These will be installed along with the
stabilizer and rudder.
£ 4Assemble the elevator and elevator push rod
assembly. If using a clevis be sure to use a
keeper, usually made from a short section of
fuel line.
Place the stab assembly in the stab cradle and
mark the covering for removal. Trim the ma-
terial about 1/16” inside this line and remove
the center section covering.
£ 6Place the rudder linkage and horn into posi-
tion in the fuselage. The rudder horn will ex-
tend up through the stabilizer assembly when
installed. The rudder horn should be on the left
side of the fuselage and the linkage extends up
to the left servo opening in the servo tray.
£ 7Glue the stabilizer assembly in making sure
it is square to the fuselage and that the hinge
line is at 90° to the fuselage center line.
£ 8 Install the two ller pieces (SF) and then the
top 1/16” sheeting (T). Note that the top sheet-
ing has a hole to allow the rudder torque rod
to extend up through.
£ 9Sand the fuselage top aft section to shape and
then cover the aft top section of the fuselage.
£ 10 Test t the vertical n, and mark the fuselage
top for covering removal. Once again, re-
move the covering where the vertical n will
glue on and then glue on the vertical n.
£ 11 Install the rudder, control horn and hinges.

LANDING GEAR ASSEMBLY
Mains
The main gear struts are formed from 1/8” music wire, you will need to solder a #8 washer to the gear
leg to act as a stop on the inboard side of the wheel. On the outboard side a 1/8” wheel collar is used to
retain the wheel. If you are not familiar with silver soldering, see the Shop Tips section on my web site
www.topnotchkits.com.
£ 1Solder a #8 washer to each gear leg as shown in the photo below.
Refer to the stack order of the gear strut cover
on the plans sheet. Lay the parts out as shown
on the right to assemble a left and a right strut
cover. Glue LGD to LGB.
£ 3Glue the LGD and LGB assembly to LGA.
£ 4Use the formed wire landing gear as a spacer
and then glue LGC to LGA leaving a slot for
the gear strut.
£ 5Sand a 45° bevel on LGA at the wide end (top)
to allow clearance for the fuselage. Sand only
down to the ply core (LGD).
£ 6Install the landing gear and retain it with two 1/16” ply landing gear straps and four #2 x 1/4” S.M.
screws. Temporarily install a hinge into the strut cover assembles and test t them onto the gear. Mark
the location of the outer most center hinge hole on the fuselage, drill a 1/16” hole for a #2 x 1/4” S.M.
retainer screw and install.
£ 7Install the 1/16” ply gear retainer clip in the hole provid-
ed at the bottom of the strut. The strut cover installation is
now complete. Do not install permanently until after cover-
ing. Use a small dab of Epoxy in the hinge slot to retain the
hinge. Be sure to add about 3° of toe in to the gear leg before
nal assembly.
The strut cover parts are laid out to assure a left and right assembly. Note that the
parts on the right, LGD and LGB have been assembled and a hinge (painted black
for clarity) has been laid in position in the hinge slot in LGD. The hinge will be
permanently installed after assembly.
The installed strut cover is hinged to the fuselage at the top to allow it to ex with
the gear leg. A #2 x1/4” S.M. Screw and ply retainer tab is used to secure it at the
bottom. A #8 washer has been soldered to the inboard side of the gear to retain the
wheel, a 1/8” wheel collar is used on the out board side.
The photo on the left shows the assembled battery
hatch cover ready to be installed. The shape of these
parts will enable the cover to key into position in the
hatch cover opening and provide a secure opening for
accessing the ight pack.
In the photo on the right, the battery hatch cover has
been installed. The ange on the front of the hatch
cover will retain the front of the cover while a #2 X
3/8” sheet metal screw retains the cover. Note that the
aft edge of the cover has been sanded to contour with
the bottom of the fuselage.

TAIL WHEEL
The scale tail wheel requires some fabrication as shown on
the plans. If you do not wish to go to this trouble you can
use the simplied design shown. If you would like to use a
scale pull pull set up, you can use an E-ite HFL2282 micro
pull pull kit. This not only looks good but it also works great.
Note that in the photo on the right the tail wheel shows a lagging
link, this is not necessary and is not scale. See the addendum in
you kit regarding this change.
SETUP
The proper C.G. can easily be achieved by moving the battery pack if you are using electric power. Be sure to do a lateral
balance check to assure the model hangs wings level when supported by the motor shaft and the end of the tail cone.
Add weight to the high wing until it is wings level.
Set the initial throws as follows. Ailerons - 3/8” up and 3/8” down Elevator - 1/2” up and 1/2” down Rudder - 1” right
and left and wheel toe in of 3 degrees for best ground handling.
If you are setting your model up for oat operation be sure to use the additional n area supplied. The holes in the stab tips
is designed to hold the ventral ns. The tail wheel assembly can be unbolted and the sub n bolted in its place.
COWL FLAP
The cowl ap is functional and should not be omitted. Without it the controller may not get adequate cooling. If
you wish to omit the cowl ap you will need to make some other arrangement for cooling air to exit the fuselage.
Assemble the three CF parts but do not install the assembly until after covering.
