Suggested Radio Gear:
Note that the Micro Cap 232 was originally designed for brushed power systems. The design lends itself
very well to brushless power. When running a brushless system shoot for a motor that turns a 6-7” propeller
with authority while producing about 45-60 Watts. This should be ample power for the micro Cap 232.
Small hand wound CD Rom motors and similar outrunners readily attach to the motor stick and are capable
of the required power output. New light weight servos can also be used in place of the GWS Pico servos -
Cirrus CS101’s work great and only require minor fit modifications.

GENERAL ASSEMBLY INSTRUCTIONS:
Thank you, for purchasing this Stevens AeroModel 1:12 Scale Cap 232 (MICRO).
Please keep in mind that while small and cute like a “park flyer” this is a sport plane and behaves as such.
Therefore we recommend this kit to the advanced pilot. The tiny airframe, wheels, and building materials
exclude this model from flying from anything but and improved surface (read: sealed asphalt, concrete,
etc..). A good rule of thumb –if you cannot readily taxi and take off from the surface – do not attempt to land
there!
We hope you enjoy this model as much as we have.
Sincerely,
Bill Stevens

General Assembly Tips
READ THE INSTRUCTIONS and the plan sheet prior to starting any work!
Tape plans to work table. Cover with wax paper or plastic wrap.
Join all joints with Thin CA unless otherwise specified.
DO NOT REMOVE THE PARTS FROM THE BALSA SHEETS UNTIL REQUIRED!
DO NOT FORCE THE FIT – when in doubt double check your parts and remove material should
not be required. If you feel that you have a poor connection check first to see that the part is not
upside down. Next, referenced each piece against the plan sheet.
This is very important so I’ll say it again – Prior to gluing, test fit and match parts over the plan
sheet to ensure you have the correct pieces and orientation.
Making solid glue joints: Hold parts together on top of plan sheet using moderate pressure to fit
parts - wick thin CA into joint. (There is no need to pin parts to work table as all pieces interlock
and self - jig.)

Tail Feathers
1. Build the Rudder, Vertical Stabilizer, Elevator, and Horizontal Stabilizer. Parts are grouped
according to tail section component on the 3/32” balsa sheet. Work with each component
separately. Assemble over plan sheet, removing only those parts necessary to complete each
individual component. Though the parts fall together and self jig, pay particular attention to making
solid glue joints. (note: at the time of printing your plan sheet may reflect the old-style tail feathers
use the included update sheet to replace the parts overlay for the tail feathers as illustrated on the
plan sheet)

2. Elevator Joining Tube. Locate the provided 1/16” aluminum tube - rough the surface with fine grit
sand paper to remove dirt, oil, and debris, from the tube. Bond elevator halves over plan sheet
using thin CA tack the joining tube to each elevator halve and allow to dry. Once dry use a small
amount of 5-minute epoxy to create a fillet between the wood and the metal tube.
3. Sand all surfaces with fine grit sandpaper and bevel / taper hinged surfaces in preparation for your
preferred hinging method.
Fuselage
Fuselage components are exceptionally brittle until the entire assembly is complete. Handle parts
accordingly and do not force the fit!
1. Join over plan sheet F16A and F16B to produce 2 F16 fuselage side sheets.

2. Assemble formers F4, F5, and F6. Join over plan sheet F4A, F4B, F4C, F4D, F5A, F5B, F5C,
F5D, F6A, F6B, F6C.
3. Assemble fuselage sides over plan sheet. Parts are grouped on the 3/32” balsa sheet. Make 2
sides.
4. Locate Firewall parts F1 and F2 – if using the recommended LPS drive insert the 10mm balsa
square with the ¼” hole into both F1 and F2 (Hole should be positioned such that it is at the lower
part of the square when joined to F1/F2. Join fuselage sides to F1, F2 and F1A. Test fit parts
before gluing.

5. Install F3A, F3B and servo rails SR1-SR2. Site fuselage construction over plan sheet top view to
ensure straight and true assembly. Join each of these to the fuselage sides in their respective
positions. Note the servo rails are composed of a top piece SR1 and bottom 3/32” doublers SR2.
6. Glue F14 3/32” stringers to top of F1, F2, and F3A.
1. Pinch fuselage sides together at tail position, using a flat rat tail file or emery board bevel the
notches and alignment tabs in the fuselage to better accommodate formers F4, F5, and F6.

2. Test fit former F4 and F15 to fuselage. Align over top view on plan sheet and secure with thin CA.
Hint: Sand a slight bevel on sides of former F4 to aid fit. Again, do not force fit!
3. Proceed to install former F5 and F6 inserting F13 stringer along the bottom of the formers to jig the
assembly. Initially test fit F5 and F6 then glue F5 and F6 to fuselage sides - then glue (if the fit is
too snug bevel the notches with a rat-tail file or emery board). Only glue F13 where it makes
contact with F4, F5, and F6 – Do not glue F13 to fuselage sides at this time!
4. Test fit former F7. Capture aft section of F13 between fuselage sides, do not glue at this time.

5. Place some sort of weight over servo rails. Using a builders square hold tail section 90 degrees to
building table and glue F7 and F13.
6. Add tail gear block F11 to aft section of F13 inside fuselage.
7. Laminate F10 in position over aft section of fuselage. Important - Key F10 to top of F7.

8. Laminate F9 to F10, key to F7. DO NOT align with holes provided in F10 but key to F7.
9. Test fit F12 to F8. Lay F8 on building table, press F12 into F8 and glue.
10. Test F12/F8 assembly to formers F4, F5, and F6 (do not glue until specified). Align outer edge of
F8 with outer edge of F9 and tack glue just the aft end of both parts.

11. Test fit horizontal stabilizer in the slot created between F10 and F8. Snug F6 against F12/F8
assembly – remove horizontal stab and glue. Finish gluing parts F8 and F9
12. Glue F12/F8 assembly to F4 and F5.
13. Laminate finishing blocks to top of F8.
14. Sheet fuselage sides with F16.
15. Sheet fuselage top/front with F17. Test fit – then secure one end with thin CA. Next, gradually tack
down the sheets to the formers with thick CA.
