THANK YOU
Thank you for downloading this Micro Peregrine flying wing. These models take many hours
of work to make available to you so please don’t share the STL files with others. Send them
to www.rc3print.com where they can download the models themselves. This enables me to
continue to develop new models to make them available for download.
This document aims to help you print and assemble your aircraft. Our designs are made to
be simple, this model is designed explicitly with LW-PLA in mind, so it incorporates carbon
tube spars. If you print it from regular PLA it will obviously be heavier and you should take
this into account.
3D printers often have many differences so you may need to tweak settings to get the best
results.
Included in the document you will find Cura profiles and layouts for each part and assembly
instructions. Most of the components in the design are solid bodies, this has some advantages
over hollow bodies in that you can adjust some settings such as wall thickness, infill
percentage, etc. As such we recommend using Cura to slice the files though it is not
required for this model. The walls of these solid bodies are single line 0.4mm thickness to
reduce weight. As you are printing and assembling the model yourself we take no liability
for damage or loss resulting from your use of these files. Please fly responsibly and follow all
local laws.

A WORD ON RETRACTIONS
With regular PLA a common problem is under extrusion at layer change - to fix this increase
the setting extra prime amount in Cura.
With LW-PLA it is recommended to switch retractions OFF since trying to retract the
foaming filament can cause problems. If you need to fix under extrusion you can still use the
method above but will need to turn retractions ON and set the retraction distance to 0mm.

ASSEMBLY
1. THROUGHOUT THE BUILD, ADHESIONS SHOULD BE
CAREFULLY REMOVED AND FACES TO BE GLUED
TOGETHER SHOULD BE SANDED FIRST TO ENSURE
GOOD CONTACT. THIS IS CRITICAL. TIME TAKEN
HERE WILL ENSURE YOUR AIRCRAFT IS STRONG.
FUSELAGE
-Glue to the two fuselage pieces together, the main piece and the nose piece
WINGS
-Cut your carbon tube to size, you can then build your wing around this. The tube doesn’t
have to be glued in place however, this is so that it is easier to remove it incase you have a
crash and want to use it again. Because of filament blobs and expansion you will need to
carefully clear out the ends of the holes for the carbon rod in the wing pieces.
-Starting from the root build the wings sections up using the carbon tube to help with
alignment. You want to be able to keep the tube free so that you can position it for the
end pieces. Don’t worry about the ailerons yet.
-Glue the winglets onto the ends of the wings. Clean up the holes for the TPU hinges in
both the aileron and wings.
-The carbon spar can now slide into the fuselage and the wings glued on. TAKE CARE TO
ALIGN THE WING CORRECTLY.
-Glue together the aileron pieces, careful not to have any glue fill up the hinge space.

-When gluing the hinges into the wings you can line the aileron up with the wings to give
enough space for the hing to move. The front of the hinge should be about 1mm away
from the wing.
MOTOR MOUNT
-The motor mount is glued onto the aft firewall of the fuselage, make sure the hole for the
mounting screw is facing up. Insert the motor and secure with a screw.
-Different types of motor can be mounted onto the firewall if needed.
-As the motor is mounted above the drag line you want to make sure the motor is
mounted with the motor angled up towards the tail a few degrees. This is built into the
PLA motor mount assuming it is mounted correctly (screw hole up).
COWLING AND CANOPY
-Glue together the two canopy sections. Clean the print at the nose section around the
latch so that it will fit.
-Glue the motor cowling in on to the firewall.
-To fit the canopy, have the plane face you, touching your stomach. Place the front latch of
the canopy into position and gently squeeze from the back. You can ease the two rear
latches under the firewall. To remove you do the same only gently ease up the middle of
the canopy edges.

MOUNTING RC EQUIPMENT, SERVOS AND CONTROL
RODS
-This is the ideal layout of Rc equipment.
-Servos first. I attach the control rods to the elevons first, cut
and bend the servo ends of the rod in the right position,
forward in the fuselage. I then make sure the servos are
centred, affix them to the control rods and fix them to the
fuselage using a dab of hot glue in each corner. It is
important when fixing them that the control surface is the
the correct position, 5 degrees up.
-For the Rx I mounded it on some spongy servo tape.
-I affix the battery with sticky velcro.

PROGRAMMING
If you are using the Cessna 182 UMX board
(EFLU5864) then you will need to reprogram
the board for elevon mixing. Whilst this can be
achieved inside your transmitter, the AS3X will
interfere with your controls, I.e. a sensed pitch
will be corrected with what it thinks is the
elevator and cause a roll!?
Using the SPMA3065 cable and the Spectrum
programming software you can easily create the
mixes, one for roll and one for pitch.
You will need to create a plug for the programming cable as the one on the adapter is the
wrong size. I simply use a spare micro servo plug.
Plug into the the programming port on the rx. The orange
wires should always be to the antenna side. Connect the
usb to your PC and plug in the models battery.
I won’t go into AS3X tuning here, there is plenty of
information from those more knowledgeable than me
online. I have the AS3X gains turned off.

Micro Velocity XL

To set up the elevon mixing follow the settings in the screenshots


ADVICE FOR MAIDEN FLIGHT
Make sure the control surfaces are moving correctly! The battery should be positioned such
that it won’t move, I tend to use sticky velcro for this.
Check the CG. Check the CG again! For your maiden flight the CG should be located around
15mm behind the spar at the wing to body join, there is a small indentation on the wing at
this point. After a successful maiden the CG can be moved back, theoretically put to another
20mm.
If hand launching, be careful of your hand on the prop, you can launch holding the front of
the wing root rather than the fuselage to keep your hand clear. The aircraft has a strong
pitch down tendency at low speeds so launch with the motor on full power with a good 45
degree launch angle. You may need to hold a bit of up elevon until it is up to speed. For the
maiden it is advisable to have a friend help, long grass helps swell.
Have fun!
