Pober Pixie - Background
The Pober Pixie (360) is our sport scale rendition of Paul Poberezney’s home built classic. Mr.
Poberezney needs no introduction to the EAA home built community and is a veritable legend in these
circles with several designs to his credit. The Pixie, while a completely modern subject, echos back to the
golden age of flight and those early “Helmet and Goggle” days. Taking construction and styling cues from
the likes of Ed Heath and his 1930’s LNB parasol.
This kit allows you to build a fine sport scale version of this classic from the homebuilt community. Color
schemes abound for this beauty, it seemed fitting, however, to use the classic scheme in our example
model. (AeroFILMTM Medium Blue, AeroLITETM Bright White, and Yellow and Black AeroTRIMTM)

Covering Film Requirements
While any high-quality covering film may be used to finish this model, superior results will be achieved by
using genuine AeroFILMTM brand covering film, available exclusively from Stevens AeroModel. The lower
working temperature and light weight of AeroLITETM are especially desirable for this type of model.
AeroLITETM is 1/3 the weight of typical model covering films, and will present a significant weight savings
when applied to this model.
☐1 - Roll AeroLITETM or AeroFILMTM
☐1 - Roll AeroTRIMTM in contrasting color (suggested)
Sealing Bare Wood
While not required, it is suggested that a high-quality clear lacquer be used to protect and seal any
unfinished wood. One single light coat of clear lacquer should be sufficient to protect any painted or bare
spots on the model from moisture, without adding significantly to the model’s final flying weight.
Many parts of this model may be colored using a lacquer-based spray paint. Listed below are some of
the products we have used on our models. Please feel free to use whatever products you prefer.

General Assembly Instructions
Thank you for purchasing the Pober Pixie (360) 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 don’t hesitate to
contact our staff with your questions.
IMPORTANT!
Please READ and RE-READ these build 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 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 tube that this kit was shipped in as a non-stick barrier between your work surface and the
product assembly.
Bonding the Assembly
This product’s tabs and notches interlocks 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.
Manual Updates

Fuselage
Note: If you will be using HS-55 or similar servos, the openings in F1 will need to be enlarged prior to
construction. The proper size opening is indicated by the dashed cut-line around the existing opening in
F1. If using HS-35 or HS-40 servos, no alteration to F1 will be required.
Fuselage parts are designated with an “F” followed by a numeric. Parts have been numbered so that the
fuselage assembly and required parts follows in numeric order from F1 to F52.
The assembly is a traditional central crutch with sheet sides and shape stringers. Many of the formers
will need to be installed in a forward and top orientation. Unless otherwise specified, formers should
be installed with the etched part number facing the front of the assembly and any top or bottom
designations followed.
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 small drop of medium CA glue applied 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. Lay ply part F1 on the table with the etched “Top” side down. Fit ply part F2 to the slots in
F1 as indicated in photo #1.
2. Assemble former F3 from parts F3a and F3b. Bond with thin CA.
3. Slide the narrow rear portion of F1 through the opening above F3b.
4. Fit the tab in F3 into the slot in F1. Note: The slot is oversized. F3 should be positioned in
the forward portion of the slot, leaving room in the rear portion of the slot for parts to be
installed at a later step. Do not bond.
5. Fit and tack glue the ply side rails F4 to the slots at the bottom of F3. Note: The slot is
oversized. Position F4 in the upper portion of the slot, leaving the lower portion of the slot
open to receive parts in a later step. Tack glue only. If you make a mistake in positioning
this part, you will want to be able to re-position it without having to deal with removing a lot
of glue! The other end of both parts F4 will remain free of the main structure for now.
6. Fit and tack glue ply former F5 to the forward ends of both F4‘s. Do not bond F5 to any
other part at this time. As in the previous step, the slots are oversized. Fit parts F4 into the
upper half of these slots, leaving the lower portion of the slot open to receive F6 in the next
step. Tack glue only.
7. Fit parts F6 into the lower portion of the slots in F5, which are also occupied by parts F4.
The arrows on both F6’s should point towards F5 and the front of the assembly. Tack glue
both F6’s to the F4 that they are mated with.

8. Fit two F7’s to the lower portion of the slots in F3, also occupied by parts F4. The arrows on
both F7’s will point forward, toward the parts F6 and the front of the assembly. Note: There
will be a 1/16 in. gap between parts F6 and parts F7, which will receive a strut mount tube
at a later step. Handle the assembly carefully. The F4, F5, F7 part of the assembly will be
secured during the next two steps.
9. Fit and tack glue fuselage side F8 to the right central crutch assembly, engaging the tabs in
F1, F2, F3, F5, and the F4/F6/F7 assembly into the appropriate slots in F8. Note: The tabs
on F2, F3, and F5 will fit in recesses along the edges of F8.
10. Repeat process in step 9 to fit and tack glue fuselage side F9 to the left fuselage assembly.
11. Fit F11 to the fuselage assembly, fit and tack glue F10 to the tabs on the forward portion of
F1. The recesses in the rear edge of F10 will trap F2 between F10 and F8. The lower tab
on F2 will occupy an oversized recess in F10, which will also receive the tab on F11 in the
next step.
12. Fit the tab on on end of F11 to the slot in F10, which is also occupied by the tab in F2.
13. Fit and tack glue F12 to the left side of the assembly, engaging the tabs on F1, and trapping
the tabs of F2, F5, and F11 between F12 and F9.
Check for proper square of the assembly then bond all mating surfaces with CA glue.
14. Fit and bond part F13 to the bottom of the forward part of the fuselage assembly, engaging
the tabs on each side to the slots in F10 and F12.
