Thank you for purchasing the Mountain Models PeregrinE™Micro. The PeregrinE™is a micro model
designed to bring back that nostalgic feeling of yesteryear, in anindoor electric package. Taking inspiration
from many different planes of the past, we developed the 23.7 inch PeregrinE™, which resulted in a super
easy to fly, lightweight, and nostalgic indoor electric R/C airplane.
The PeregrinE™ was designed using a state of the art 3D CAD package, to allow for exceptional interlocking
parts design and fit. 3D design also allows us to provide clearer assembly images, without having to use
photos.
The PeregrinE™ is built from self-jigging interlocking laser cut balsa and plywood parts. It's like a 3D jigsaw puzzle
with instructions. Although not needed for building, full size plans are included for reference. If the instructions are
read before hand and followed during the build, the Little Bogie™ can be built up and ready to fly in only a few
evenings.
We think you’ll like the PeregrinE™ and look forward to any feedback you might have.
Thank you,
Brian Eberwein

General Building Tips
•READ THE INSTRUCTIONS all the way through and study the plans BEFORE starting any
work on the model.
•PRE-SANDING: BEFORE removing any parts from the balsa sheets, use a sanding block
with 320 grit sandpaper and lightly sand the back of the balsa sheets. Our balsa suppliers
have been sending us wood that is over sized, so sanding the backs of the balsa sheets
reduces the thickness just slightly and removes any charring from the laser cutting process.
•Tape the plans to your nice clean work surface and cover it with wax paper or plastic wrap.
You want to keep your work surface clean and not glue the parts to the plans, right?
•Balsa is a lightweight and fragile wood, so you do need to be careful with it; however, you
will also need to use a little bit of force to make everything fit properly, so don’t be too
timid.
•Do not remove any pieces from the balsa sheets until they’re ready to be used. That way,
parts won’t get mixed up or disappear.
•Do NOT glue anything until told to do so.
•Join all of your pieces using thin CA (Cyanoacrylate) glue, unless we tell you otherwise. In
general, only a small amount of CA is necessary to glue parts together.
•Don’t over force your pieces together. If they aren’t fitting together properly, make sure you
have the right pieces and that they are oriented correctly. If needed, you can lightly sand
the part to fit after making sure it is the correct part and oriented correctly. On balsa “tabs”,
you can “pinch” the wood with your fingers to get them to fit in slots. (The tabs might be
tighter some times, due to tolerances in wood thickness)
•If you want to remove the charred edges caused by the laser cutting process, lightly
dampen a cloth with bleach and gently rub the affected areas. Removing the char will not
increase the strength but will make it look better. It also keeps that dark edge from showing
under the lightweight coverings. You can also remove it by LIGHTLY sanding with 400 grit
sandpaper.

1. Slide the 4 ea. W5 ribs, W6 rib, and W7 rib onto the LEFT side of the spars, W1 and W2. Be
careful with W6 and W7 since the spars do not rest on your table there. Use a finger on the
bottom of the spars when pressing these ribs in place. Do NOT glue them in place yet.
2. Press the ribs into the W4 trailing edge part. Do NOT glue.
3. Press the ribs into the W3 leading edge support part. Do NOT glue.
4. Press the W9 leading edge onto W3 and fully up
against the ribs. Do NOT glue.
5. After making SURE that all the parts are fully
seated against each other and aligned with the
plans, and holding the parts down FLAT (small
weights are great for this), secure all the joints
with thin CA.
6. Press the wing tip W10a/W10b parts together and glue with thin CA.
Do this to make 2 wing tips.
7. Press one W10 part into place on the left side of the wing. Be careful
when pressing it onto the spars. Use one of your fingers on the bottom
of the spar to keep from breaking it when installing the wing tip. When
happy with the fit and you are sure that it is full seated against the
ribs and leading edge, glue it in place with thin CA.

8. Slide the 4 ea. W5 ribs, W6 rib, and W7 rib onto the RIGHT
side of the spars, W1 and W2. Be careful with W6 and W7
since the spars do not rest on your table there. Use a
finger on the bottom of the spars when pressing these ribs
in place. Do NOT glue them in place yet.
9. Press the ribs into the W4 trailing edge part.
Do NOT glue.

against each other and aligned with the plans, and holding
the parts down FLAT (small weights are great for this),
secure all the joints with thin CA.
14. Press the remaining W10 part into place on the
RIGHT side of the wing. Be careful when pressing it
onto the spars. Use one of your fingers on the
bottom of the spar to keep from breaking it when
installing the wing tip. When happy with the fit and
you are sure that it is full seated against the ribs
and leading edge, glue it in place with thin CA.
15. Sand the leading edge at the wing tips to match the
profile shown on the plan sheet. Sand the leading
edge of the wing to the shape as shown on the plan
sheet.

26. Press F12 into F11 and then press in place
between the fuselage sides. Do NOT glue it yet.
27. Press F13 in place on the fuselage top,
with the pushrod slot on the RIGHT side
of the fuselage. Make sure the fuselage is
straight and square and secure the joints
with F11, F12, and F13 with thin CA.

F20
F13
28. Glue the F20 parts in place in the
inside of the fuselage sides.
29. Press F13 in place. Once again, ensure
that the fuselage is straight and glue
with thin CA.
30. Lightly sand the fuselage with 320 grit
sandpaper.
31. Assemble the 3 wheels, as shown on the plans.
32. Bend and cut the main landing gear wire, as shown
on the plans, and then bend and cut the nose gear
wire, as shown on the plans.
33. Secure the wheels to the landing gear, as shown on
the plans.

F18
F17
34. Assemble the horizontal stabilizer and vertical fin, as shown on
the plans, with thin CA.
35. Lightly sand the stab, elevator, vertical fin, and rudder with 320
grit sandpaper.
36. Cover your airplane with SoLite, tissue, or silkspan. Do NOT use
heavier coverings, as this is a light weight model and heavier
coverings can easily damage the structure of the wings and tails.
37. Press the landing gear into the slots on the
fuselage bottom. Press in the landing gear
retaining parts, F17 and F18. You can use thin
CA to glue in the retainers, if you do not want
to remove the landing gear later on.

38. Cut the 1/8" dowel to 2 lengths that are
1-13/16" in length. Install in the fuselage, as
shown on the plans.
39. Hinge the elevator to the stabilizer using hinge tape,
as shown on the plans. There should be a small
(1/64") gap between the parts. Do the same for the
rudder and vertical fin.
40. Glue the vertical fin into the horizontal stabilizer.
MAKE SURE that they are perpendicular (90 degrees)
to each other!!!!

41. Glue the stabilizer/vertical to the fuselage.
Follow the direction on the plan sheet!
42. Follow the directions on page 2 of the plans to
make and install the pushrods and control horns.
43. Slide the control horn onto the Z-Bend and
then glue the control horn into the elevator.
44. Slide the control horn onto the Z-Bend and
then glue the control horn into the rudder.

45. This is a "Lazy-Z" Bend. Notice that after it goes
through the servo arm, the wire goes UP.
46. Trim the mounting 'posts" off the gearbox and glue
the motor/gearbox in place, using a couple drops of
thick CA. The motor will have slight RIGHT thrust,
once installed.
47. Hook up your motor wires to the TX, secure the
battery in the fuselage with Velcro, mount the wing,
and balance your model where shown on the plans.
45. Enjoy flying your PeregrinE Micro model! If you need
