Swift (100) - Background
Loosely inspired by the 1930 Comper Swift. The Stevens AeroModel Swift (100) is a “toon” version of the
British classic and features spunky lines and solid sport aerobatic performance. Designed to receive
popular E-Flite micro electronics, the 3 oz flying weight and low wing loading of the Swift 100 makes an
ideal model for larger indoor venues or smaller outdoor flying sites.

Builder’s Notes

General Assembly Instructions
Thank you for purchasing the Swift (100) from Stevens AeroModel.
This model has been developed and manufactured using state-of-the-art CAD/CAM systems. Our kits
feature a unique interlocking construction process, that when compared to traditional building methods,
saves 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 an experienced builder and pilot. If at any time during the assembly
of this kit, should you run across a term or technique that is foreign to you, please contact our staff with
any questions.
IMPORTANT!
Please READ and RE-READ these build instructions along with any other included documentation before
starting your build and/or contacting our staff for builder support.
Pre-Sanding
DO NOT SKIP THIS STEP. Before removing any parts from the laser-cut sheet wood, use a sanding
block loaded with 250 - 400 grit sandpaper and lightly sand the back side of each wood sheet. This step
removes any residue produced as a result of the laser cutting process. We have found that most stock
wood sizes run several thousandths of an inch oversized. This step also slightly reduces the thickness of
each sheet of wood. Leave all parts in the sheet wood until required for assembly.
Protecting Your Work Surface
Use the poly bag that this kit was shipped in as a nonstick barrier between your work surface and the
product assembly.
Bonding the Assembly
This product’s tabs and notches interlock like a 3D puzzle. We strongly suggest that when fitting parts,
you dry fit (use no glue) the parts together first. It is advised to work 1 - 2 steps ahead in the instructions,
using this dry-fit technique. This allows the opportunity to inspect the fit and location of assembled
components, and shows the benefits of our construction technique. As each successive part is added, it
contributes to pulling the entire assembly square. Once you arrive at the end of a major assembly
sequence, square your work on a flat work surface and bond 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 square and
true assembly.
Unless otherwise noted in the instructions, we find it easier to “tack glue” parts (temporarily bonding parts
in assemblies, using a small dot of glue). When using medium CA glue, apply with a fine-tip CA glue
applicator. Never bond painted or covered assemblies with thin CA, as it can destroy the finish of a
beautifully prepared model.
Never Force the Fit!
This is a precision laser-cut kit. Our lasers cut to within 5 thousandths of an inch in accuracy. Yet the
wood stock supplied to us by the mill may vary in thickness by up to 20 thousandths. This variance in the
wood stock can cause some tabs and notches to fit very tightly. With this in mind, consider lightly sanding
or lightly pinching a tight-fitting tab, rather than forcing the parts together. You will break fewer parts in
assembly, and end up with a 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 F30.
Note: When initially bonding parts, use a single, small drop of medium CA glue, applied sparingly with 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 in error, if you do not soak the assembly
with glue after each step! This method of assembly will allow our interlocking design to do its job.
As each successive part is installed within the fuselage, it will help pull the entire structure square and
true. When a major assembly is completed, revisit all joints and bond completely. Do not use excessive
amounts of glue, as this only adds weight to the model.
1. Fit center crutch F2 (sheet 02/09, 1/20 in. balsa) to right fuselage side F1 (sheet 01/09, 1/20
in. balsa) observing “Top” orientation etched on part F2.
2. Fit and bond F3a (sheet 01/09, 1/20 in. balsa) to F3b (sheet 02/09, 1/20 in. balsa) to make
former F3. Note: Upper tab on F3 extends beyond outer surface of fuselage side.
3. Fit and tack glue formers F3 and F4 (sheet 04/09, 1/20 in. balsa) at each end of crutch F2,
as indicated on the plan..
4. Fit battery tray F5 (sheet 03/09, 1/20 in. balsa) to fuselage side and F5 observing “Bottom”
orientation.
5. Fit ply part F6 (sheet 09/09, 1/32 in. ply) to fuselage side and F5.
6. Fit former F7 (sheet 01/09, 1/20 in. balsa) to F5 and fuselage side.
7. Fit ply motor mount F8 (1/16 in. ply) to fuselage side. Inspect fit of all formers installed in
steps 1-7. With parts properly seated, proceed to tack glue each former to retain within
fuselage assembly at the tab and notch locations.
8. Fit F9 (sheet 08/09, 3/32 in. balsa) to fuselage side and F2. Tack glue to retain.

30. Sand fuselage lightly. Sand cockpit side flush with edge of former F4. Round corners of
nose. Bevel edges of F20 with fuselage sides. Set fuselage aside until final assembly.
Tail Group
The horizontal and vertical stabilizers, rudder, elevator, and sub-fin are designated with a “H”, “V”, “R”, or
“E”, as appropriate, followed by a numeric. Parts have been numbered so that the assembly and required
parts follows in numeric order. Assemble parts over the plan, protecting the plan with the poly bag that
this kit was shipped in.
31. Dry assemble horizontal stabilizer over the plan, from parts H1 through H5 (sheet 07/09,
3/32 in. balsa). Bond with thin CA. Lightly sand stabilizer, rounding the leading edge and
leaving the trailing edge square. Locate the elevator part E. Bevel the straight leading
edge at a 45 degree angle, following the “Elevator and Aileron Tape Hinge Diagram “ on the
wing detail sheet. Lightly sand the elevator, leaving the trailing edge square.
32. Dry assemble the vertical stabilizer and rudder over the plan from parts V1 through V5
(sheet 08/09, 3/32 in. balsa) and R1 through R4 (sheet 08/09, 3/32 in. balsa). Bond rudder
and stabilizer parts with thin CA. Note: do not bond rudder to the stabilizer. Lightly sand
stabilizer, rounding the leading edge and leave the trailing edge square.
Bevel the leading edge of the rudder at a 45 degree angle, following the “Rudder Tape
Hinge Diagram” on the fuselage detail sheet. Lightly sand the rudder, leaving the trailing
edge square.
Wing
The wing is composed of one spar, leading edge, trailing edge, ribs and tip sheeting. 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 W15.
The wing is assembled one half at a time - left side first, then mirror build sequence to the right side.
When a part is required in the build sequence (for instance “W3”) refer to the detail sheet for part
placement.
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.
33. Begin by building left half of wing. Join parts W1a (sheet 05/09, 1/16 in. balsa) and W1b
(sheet 05/09, 1/16 in. balsa) along the matching dove-tail joints, to create W1 main spar.
Using the detail sheet as a guide, dry fit left side rib W2 (sheet 05/09, 1/16 in. balsa) to main
spar W1. Note: The bottoms of all ribs should seat flush with bottom of spars.
34. Fit rib W3 (sheet 05/09, 1/16 in. balsa) to outer slot of spar W1. Refer back to plan for part
placement.
35. Fit trailing edge W4 (sheet 07/09, 3/32 in. balsa) to ribs W2, and W3. Properly seat then
tack glue assembled parts to retain within assembly.

trailing edge W4. Square assembly over the plan and tack glue ribs to spar and trailing
edge.
37. Fit and tack glue tip support W7 (sheet 05/09, 1/16 in. balsa) to rib W3. Note: upward taper
on part W7 should match that of spar.
38. Repeat “□□” steps 33 through 37 to complete the rib installation for right half of the wing.
39. Fit one each 12 in length of 1/4 in. square balsa, leading edge stock, beginning each piece
to share a “landing” point centered across the thickness of either left or right W2 rib (see the
detail sheet set for additional guidance). Seat the leading edge stock within the squared
notches cut to the leading edge of the wing ribs. Bond with medium CA to retain the
leading edge within the wing assembly.
40. Assemble two wing tips W8 from parts W8a (sheet 05/09, 1/16 in. balsa) and W8b (sheet
05/09, 1/16 in. balsa). Bond W8a/b with thin CA.
41. Fit left wing tip W8 to tab on leading edge of left rib W3. Align Leading edge of wing tip
along back surface of leading edge stock and against forward portion of rib W6. Tack glue
along leading edge to retain. Repeat process for right wing tip. Allow glue to cure prior to
completing next step.
42. With wing held flat against the table, bend left wing tip over rear portion of ribs, fitting to tab
on W7 and notch in aft end of rib W3. Tack glue to hold position then revisit wing tip with
CA to thoroughly bond part to assembly. Repeat for the right wing tip.
43. Trim excess leading edge stock just beyond left rib W3. Repeat for right side.

the notches over the spar and bond to the spar and ribs with medium CA. Fit W10 in the
notches in the forward portion of the ribs and nesting within slot at wing tip. Bond with
medium CA.
45. Fit and bond W11 (sheet 02/09, 1/20 in. balsa) to the bottom of ribs W2
46. Fit and bond the left and right ply servo mounting plates W12 (sheet 09/09, 1/32 in. ply) to
the notches in left and right of spar W1 and ribs W5.
47. Bond the left and right balsa servo cuffs W13 (3/16 in. balsa) to the BOTTOM of each left
and right servo mounting plate, to create a pocket for the servo to rest in.
48. Fit ply trailing edge reinforcement W14 (sheet 09/09, 1/32 in. ply) within notch of part W4 at
trailing edge of wing. Bond with medium CA glue.
49. Use the detail sheet as a guide for proper positioning of balsa diagonal sub ribs W15 (sheet
05/09, 1/16 in. balsa). Fit right and left sub ribs to assembly, hold wing flat against your
building board and bond with medium CA to retain parts.
50. Sand the leading edge to shape. Match the contour of the leading edge to fit the wing
saddle on the fuselage. Flow the leading edge smoothly into the wing tip.
51. Dry assemble ailerons from parts A1 through A5 (sheet 06/09, 3/32 in. balsa). Bond with
thin CA. Following the “Elevator and Aileron Tape Hinge Diagram” on wing plan sheet,
bevel the underside of the leading edge of the ailerons at a 45 degree angle. Note: Ensure
that you sand the leading edges on the correct side so that you will end up with a LEFT and
a RIGHT aileron.
