THANK YOU
Thank you for downloading this P180 Avanti 2. 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
gauge interest and see wether to bother making more available for download.
This is one of our experimental models and is an evolution from our first iteration of the
Avanti. Please share your build and flights with me, either through the website or on
instagram @rc3dprint!
This document aims to help you print and assemble your aircraft.
Included in the document you will find Cura profiles and layouts for each part and assembly
instructions. Many 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. The walls of these solid
bodies are single line 0.4mm thickness to reduce weight with most parts then double walled
for strength.
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.

PRINTING PROFILES
Please save the following profiles in Cura, ready to be used as required for the selected part
to be printed.
Load a generic 0.2mm layer height PLA profile into Cura for your printer, then change the
following from the default options Profile 1. Each part may have individual settings, they
will be listed in the Part Placement section of this manual.
For printing in LW-PLA you should use the same settings as below but change the
temperature and flow as required.

Save this profile as PROFILE 1 - most parts print with this profile.

PLA PROFILE 2 - L & R NACELLES
Save this profile as PROFILE 2, this is used for the
nacelles to give enough material for the motors to
screw into.
A common problem is under extrusion at layer
change - to fix this change the setting extra prime

ASSEMBLY
1. THE ELEVATOR (IN THE FORWARD WING) NEEDS TO
BE ASSEMBLED AT THE SAME TIME AS THE CANARD
IS ATTACHED TO THE FUSELAGE.
2. DON’T GLUE THE MOTOR COWLINGS IN PLACE UNTIL
YOU HAVE FITTED THE MOTORS. DON’T GLUE THE
NACELLES TO THE WINGS UNTIL YOU HAVE FITTED
ESC’S AND TESTED THE MOTORS.
3. THE AILERONS ARE GLUED IN PLACE DURING WING
CONSTRUCTION.
4. 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.
FUSELAGE
•Start with Fuselage 4 before beginning to glue together the fuselage. Insert the Fuselage
Forward (8mm Dia.) and Aft (6mm Dia.) spars into he fuselage. These spars provide
strength to the fuselage as well as allowing the wing to be removable. Try not to bend or
mishaps the fuselage when inserting them and gluing them into place.
4 MUST READ POINTS

•Glue together the sections of the fuselage with the longitudinal (8mm dia) spar. The two
middle spiralled versions will gain their strength once glued together.
WINGS
Assemble the wings around the forward wing spar (6mm dia). Be sure to assemble the
aileron with the associated hinge (3mm dia) before gluing the wing tip on. The forward and
aft wing spars should reach approximately halfway into the fuselage, if they are too long the
wings won’t fit properly.
The aileron servos are mounted in the wing on a servo tray. It is possible, depending on your
printers ability to print small holes that you may need to glue the servo tray in place. A dab
of hot glue works quite well for this.
To mount the wings to the fuselage slide the forward and aft wing spars into the fuselage
spars. Once you have BOTH wings fitted to check a tight fit, you can drill down with a small
drill bit, following the hole in the top of the fuselage wing fairing, through both wing and
fuselage spar. Suitable sized screws can then be used to secure the wings in place or remove
them. (Note: the holes should be diagonal).
NACELLES
The nacelles have blank firewalls so you need to mark and drill mounting holes for your
motors. It is advisable to leave the cowlings offuntil you have completed the build and
check motor spin direction etc.
The nacelles are fitted to the wing by gently sliding them down the wing from the tip. Take
care with the ESC and wires as they can be fiddly to get into the wing cutout. The correct
position for the nacelle is 98mm from the root of the wing (not the wing body fairing). This
leaves 250mm clearance for a 9 inch prop. If using a longer motor it may be possible to fit a
10 inch prop.
CANARD

The canards are fitted to Fuselage 1. There is canard spar to provide strength against
accidental knocks. The elevator needs to be assembled in place at the same time as fitting
the canard.
The servos are mounted in the underside of Fuselage 1 for the elevator.
EMPENNAGE
The empennage is simply glued together. There is a horizontal stab spar for resistance to
accidental knocks.
STEERABLE NOSE GEAR
There are 2 steering discs. These are primarily to strengthen the area for a steerable nose
gear when printing Fuselage 1 from LW-PLA. They should be printed in PLA with 20%-30%
infill. The 2mm wire used for the nose gear can then be place through the fuselage and discs
and the disc spread the load with a collet on either side of the fuselage to hold the wire in
place. The Steering arm should be glue to a collet.
