General Assembly Instructions
Thank you, for purchasing this Stevens QuickOats™(250), inspired by the venerable 1937 Quaker free
flight model line, with a touch of “toon” style. This product has been developed and manufactured using
state of the art CAD/CAM systems and features a unique interlocking construction process that, when
compared to traditional methods found in other model aircraft kits, save countless hours of measuring,
cutting, sanding, and fitting. We are certain that you’ll find our kit to offer a truly exceptional build
experience. As this kit is recommended for the novice model builder and pilot; we invite beginners who
have purchased this kit to seek the help of a seasoned builder and pilot. At any time should one run
across a term or technique that is foreign please don’t hesitate to contact our staff with your questions.
READ THIS!
Please READ and RE-READ these instructions along with any other included documentation prior to
starting your build and/or contacting our staff for builder support.
Pre-sanding
Do not skip this step. Prior to removing any parts from the laser cut sheet wood use a sanding block
loaded with 250-400 grit paper and lightly sand the back side of each sheet of wood. This step removes
any residue produced as a result of the laser cutting process and, as we have found that most stock wood
sizes run several thousandths of an inch over sized, slightly reduces the thickness of each sheet.
Leave your pre-sanded parts in the sheet until required in the assembly process.
Protecting your worktable
Use the poly tube that this kit was shipped in as a non-stick barrier between your worktable and the
product assembly. Promptly clean up any epoxy spills with rubbing alcohol and a disposable towel.
Bonding the assembly
As this product tabs, notches, and otherwise interlocks like a 3D puzzle we suggest that when fitting parts
you dry fit (use no glue) the parts together first. It’s advised to work 1-2 steps ahead in the instructions
using this dry-fit technique which allows ample opportunity to inspect the fit and location of assembled
components and realizes a benefit as each successive part contributes to pulling the entire assembly
square. Once you arrive at the end of a major assembly sequence square your work on top of a flat
building table and revisit the dry fit joints with glue. Using the dry-fit process you’ll be able to recover from
a minor build mistake and will ultimately end up with a more square and true assembly.
Unless otherwise noted in the instructions we find it easier to tack glue part (temporarily bonding parts in
assembly using a small dot of glue) using medium CA glue applied with a fine-tip CA glue applicator tip.
Tight fitting joints should be bonded using thin CA glue applied, sparingly, with a CA glue applicator tip.
Never force the fit!
Remember this is a precision cut kit our machines cut to within 5 thousandth of an inch in accuracy. Yet
the wood stock supplied by the mill may vary in thickness by up to 20 thousandths. This variance in the
wood stock can cause some tabs/notches to fit very tight. With this in mind, consider lightly sanding, or
lightly pinching, a tight fitting tab rather than crushing and forcing your parts together. You’ll break fewer
parts in assembly and will end up with a more square and true airframe.

Fuselage
Fuselage parts are designated with a “F” followed by a numeric. Parts have been
numbered so that the fuselage assembly and required parts follows in numeric order
from F1 to F20 (F20 used in final assembly step 82).
The fuselage is of traditional sheet side with central crutch assembly. Many of the
formers will need to be installed in a FORWARD and TOP orientation. Unless
otherwise specified by an etched “TOP” or “BOTTOM” designation, formers should be
installed etched part number right side up and facing the FRONT of the assembly.
You will dry fit the majority of this fuselage assembly together only gluing at the final
instructional steps. When parts cannot easily be retained with friction, use a single tiny
drop of medium CA glue applied sparingly through a CA glue applicator tip to “tack glue”
the part in place. Should you commit an error in assembly it will be easier to recover
from the mistake and remove or correct the part fit in error if you do not slather the
assembly in glue after each step! Further, this method of assembly will allow our
interlocking design to do it’s job as each successive part installed within the fuselage
will help pull the entire structure square and true.
1. Fit the balsa instrument panel F2 to the ply central crutch F1, with the
etching facing the REAR of F1 - see picture #1.
2. Fit and tack glue former F3 to the REAR of F1. Ensure that the end marked
“TOP” is positioned up.
3. Assemble the fuselage side F4. Fit and bond F4b to F4a, then fit and bond
the uprights F4c and F4d in place. F4c and F4d have half round tabs that
ensure they can be inserted correctly.
4. Fit the central crutch assembly to the fuselage side F4. Ensure that all tabs
are seated fully, and that all mating surfaces are flush against each other.
Tack glue the assembly if necessary, but do not thoroughly bond.
5. Fit the ply motor mount F5 to the FRONT of F1 and to F4. Ensure that the
end marked “TOP” is up.
6. Fit the landing gear brace F6 to the BOTTOM of F1 and the FORWARD
edge of the slot within fuselage side F4.
7. Coat one side of the ply windscreen frame F7a with thick CA. Carefully
position balsa F7b over F7a, matching INSIDE and OUTSIDE edges, to
create “F7” windscreen frame.

32. Fit part H4 to the end of the hatch nearest the cooling vent hole, fitting it
under the ends of the hatch rails. Bond with thin CA.
33. Check and re-check the polarity of the magnet in the previously
installed “Hatch Catch”. Orient the remaining magnet so that when
installed in the hatch, it will attract the magnet in the catch. Press the
magnet in the hole in H4 and bond by wicking a small drop of thin CA
around the edges of the magnet.
34. Fit H5 to the other end of the hatch, slipping it under the ends of the hatch
rails. H5 will extend beyond the hatch slightly, creating a “lip” that will
engage the FORWARD edge of the hatch opening in the fuselage. Bond
with thin CA. Now test fit of hatch to fuselage.
With hatch installed within fuselage, lightly sand the entire assembly,
removing any excess glue on the surface, and generally smoothing the
exterior in preparation for covering.
Set the completed fuselage aside until the Final Assembly.
Tail Surfaces
35. Build the horizontal stabilizer by fitting and bonding parts H1 through H5
over the detail sheet. Lightly sand the stabilizer, rounding the leading edge
and leaving the trailing edge square.
36. Build the elevator halves by fitting and bonding parts E1 through E4 over the
plan on the detail sheet.
37. Join the elevator halves with the hardwood part E5. Line up the assemblies
and E5 against a straight edge, over the plan, and bond. Lightly sand the
assembly, leaving all edges square.
38. Build the vertical stabilizer by fitting and bonding parts V1 through V4 over
the plan on the detail sheet. Lightly sand the stabilizer, rounding the leading
edge and leaving the trailing edge square.
39. Build the rudder by fitting and bonding parts R1 through R5 over the plan on
the detail sheet. Lightly sand the rudder, leaving all edges square.

Tail Surfaces Continued
40. Follow the Tape Hinge diagram on the detail sheet to bevel the leading edge
of the rudder and the elevator at a 45 degree angle. This is best done by
aligning the leading edge of the control surfaces along the edge of a table.
Sand the bevel, using the edge of the table as a “stop” so that you will not
sand too much off.
Set the completed tail surfaces aside until Final Assembly.
Wing
Wing parts are designated with a “W” followed by a numeric. Parts have been
numbered so that the wing assembly and required parts follows in numeric order from
W1 to W22.
The wing is of traditional spar and rib construction, with sheet wingtips and diagonal
braces within the wing. You will begin by building the LEFT half of the wing first, the the
RIGHT half, and finally the CENTER section and details.
You will dry fit the majority of this wing assembly together only gluing at the final
instructional steps. When parts cannot easily be retained with friction, use a single tiny
drop of medium CA glue applied sparingly through a CA glue applicator tip to “tack glue”
the part in place. Should you commit an error in assembly it will be easier to recover
from the mistake and remove or correct the part fit in error if you do not slather the
assembly in glue after each step! Further, this method of assembly will allow our
interlocking design to do it’s job as each successive part installed within the wing will
help pull the entire structure square and true.
41. Fit and bond “W1” main spar parts W1a and W1b together.
42. Fit and bond “W2” REAR spar parts W2a and W2b together.
43. Fit one rib W3 to the LEFT slot of the two CENTER slots in the spars.
44. Fit rib W4 to the next set of full-depth slots out from rib W3.
45. Fit rib W5 to the next set of full-depth slots out from rib W4.
46. Fit the tailing edge W6a to the REAR of all three ribs.
47. Fit trailing edge gusset W6b to W6a and rib W3. Now tack glue W6a
trailing edge and W6b trailing edge gusset to assembly.

W7, between rib W3 and W4. In the same manner, fit sub-rib W9 between
ribs W4 and W5.
50. Fit rib W10 to the notches at the end of the main spar and leading edge
web. tack glue at the leading edge web only. The aft end of the rib will butt
up against the REAR spar.
51. Fit and tack glue the leading edge W11 to the tabs on the leading edge web
and the FRONT of all ribs. Note: Arrow on W11 should point towards wing
CENTER.
52. Assemble the LEFT wing tip sheeting “W12L” by fitting and bonding W12a
(L) and W12b(L) together.
53. Fit W12 to the FORWARD tab on rib W10, with the leading edge of W12
flush with the leading edge W11. Tack glue along the leading edge only.
54. Carefully bend the sheeting over the spars and ribs W5 and W10. Ensure
that all the tabs are seated fully, and that all mating surfaces are flush with
each other. Bond all mating surfaces.
Tip: Moisten the TOP of the sheeting with glass cleaner, and allow to soak
in for a few minutes - this will make the sheeting easier to bend. Tape part
in place and allow to dry completely. Only bond to assembly once part has
completely dried.
55. Dry fit diagonal brace W13a between rib W3 and sub-rib W8, with the wide
end fitting in the corner of rib W3 and the main spar. The smaller end will fit
in the notch within the leading edge web W7 near the tip of rib W8.

main spar, and the leading edge. With wing held flat to your building surface
thoroughly bond wing panel parts by wicking medium CA along all mating
surfaces.
Complete the RIGHT wing panel. Repeat steps 43 through 56 marked ☐☐
to build the RIGHT half of the wing.
57. Fit the CENTER section trailing edge part W14 between the REAR portions
of ribs W3 and tack glue in place.
58. Fit and tack glue the CENTER section leading edge web W15 to the FRONT
of ribs W3. Note: Arrows on W15 should point towards wing leading edge.
59. Fit and tack glue the CENTER section leading edge W16 to W15. Hold the
CENTER section down on a flat surface, and thoroughly bond the CENTER
section parts by wicking medium CA along all mating surfaces.
60. Fit and bond the ply trailing edge brace W17 to the recess in the trailing
edge, spanning both W6’s and W14.
61. Assemble the spar cap by fitting and bonding parts W18a and W18b
together.
62. CENTER the spar cap over the main spar W1, fitting it into the notches
along the tops of each rib and at the wing tip sheeting. Bond to the main
spar W1 and the rib with thin CA.
63. Fit two sets of turbulator spars W19 and W20 to both RIGHT and LEFT wing
panels within the remaining notches along the top the wing ribs. W19 will
install to the notches nearest to the main spar, and W20 in the notches
nearest the leading edge. Both spars will key in the notches in the wing tip
sheeting, and end CENTERED within the slots in ribs W3. These slots
should not be completely filled by the spars, as there must be room for the
CENTER section spars to fit in these slots as well. Do not bond.
