„Fatty“
From the Fatty Season:

building instructions
The model of the Mustang B as a "cartoon variant" is part of the
Fatty Season, which is available here in the shop. The models are
simple in construction and allow a quick construction progress.
The wing for example. consists of only a few components. The
selected "KF" profile thus facilitates the construction. The Mustang
can be started well from the hand. It can also be installed a
retractable landing gear.
Technical specifications:
• Span: 800 mm
• Hull length: 670 mm
• Weight: about 800 grams (depending on engine, retract and
battery selection)
•Motorization: DT 750 kV or Turnigy D2836/11 750 kV
• Controller: 2S: 20 A / 3S: 25 A
• Propeller: 12 X 6 inches
• Battery selection: 2S 1300 mAh until 3S 800 mAh
• RC function: Elevator / Rudder / Aileron and Throttle

The Depron components are precisely cut using a CNC machine.
Positions of all adjacent components were also marked and
labeled with CNC. In this way it can be ensured that all adjacent
components can be glued to fit easily.
The illustration shows the contents of the kit:
plus Planking material 3 mm, 6 mm Depron Heling and the PVC
canopy

The manufacture of all components and the completeness of the
kits were carried out by hand and conscientiously. If you notice
any inaccuracies in fit or missing components, please contact me
in order to be able to offer you and the following customers the
most satisfactory product possible. [email protected]
General:
The building material DEPRON is a very light building material that
is normally used in house construction. In hardware stores you
can find it in wallpaper departments under the name
"Untertapete" as an insulation layer under the wallpaper. Due to
its low weight (e.g. 10X10 cm of 6 mm Depron weighs 2 grams)
and its stability, it is ideal for the construction of "slow flyers" up
to weight classes of well over 3 kg. So Depron has had a justified
place in the model flying sky for several years reached.
Depron processing:
Depron can be deformed cold over the edge of a table with the
palm of your hand. Grinding corners and protruding edges is done
well with fine emery paper. When cutting Depron you should use a
sharp carpet knife with a narrow blade. When bonding Depron-
Depron, UHU-Por is very suitable, unless it is under tension during
bonding, or in connection with other materials, or there is a higher
load on the bond. You take the proven epoxy resin. "Modeling
filler" from "Moldofil" from the hardware store is ideal for filling
out gaps and unevenness. The paste similar to toothpaste can be
very easily filled into the Depron column and after hardening is
hardly harder than Depron.
necessary building materials:
All necessary Depron components can be found in the Depron
parts kit. All additional necessary building materials such as
stiffening materials (CFRP, wood ect) or adhesives or RC
components are not included!

Building instructions:
1. Structure of the wing:

1. Cut out the slot for the stiffening (6x0.5 mm CFK rod, better
8X0.5 mm CFK) from the lower wing with a cutter knife according
to the marking. Glue the oversized Carbon rods flush with the
underside. The overhang serves to ensure that both Carbon rods
can be adequately glued together.
(Picture shows P38, but the same procedure)

1. Put the heling together.
1. Place the lower wing halves and grind the connection joint until
they fit neatly and the projecting Carbon lies against each other.

Image shows Fatty Zero, same procedure
1. Align both wing halves on the heling and glue them together.
Make sure that both Carbon rods are glued together.
2. Prepare aileron servos including cable extension. A notch in
both wing parts serves as a cable duct. Notch both wing parts until
the cables pass through without pressure.

For example (P38)

1. If a Carbon wider than mm was used, also cut the slot in the
upper half of the wing. Put on the upper wing half and grind the
connection joint until they fit together. Now glue the upper wing
parts onto the underside of the heling.
2. Sand the leading edge as follows:
1. 1. Fuselage assembly:
Important: side pull (top view)

2. Insert all frames, then insert stringers R3 and R4 from the side.
After all the fuselage parts have been pushed in for accuracy
testing, they can be glued.

2. Sand all frames and stringers according to the subsequent
planking:
12. Prepare tail units:
13. To stiffen a Carbon rod 6X05 mm, see gluing in the red line.
12. The elevator should also be stiffened with a 6 mm log. (Picture
shows Fatty Stuka)

12. Insert the elevator and rudder into the tail units using hinges.
13. The tail unit should be inserted before the fuselage is clad and
checked for accuracy of fit.

12. The engine should now be used in the fuselage using plywood,
Carbon or GRP. The force must in any case be distributed over
several frames and stringers. Landing on the "nose" could loosen
the engine if the attachment in the fuselage is too low.
