„Fatty“
From the Fatty Season:

Building Instruction
The RC model of the BF 109 as a "cartoon variant" is part of the
Fatty season, which is available here in the webshop. The models
are simple in construction and allow quick construction progress.
The wing consists of only a few components. The selected "KF"
profile thus facilitates assembly. The start can be done with a
starter trolley, by hand or a built-in retractable landing gear.
Technical specifications:
• Wingspan: 800 mm
• Fuselage length: 770 mm
• Weight: approx. 700 grams (depending on motorization and
battery selection)
• Motorization: DT 750 or other BL with max. 750 rpm
• Regulator: 30A
• Propeller: 13 X 6.5 inches (GWS)
• Battery selection: 3S - 1300 mAh to 3 S - 1800 mAh
• RC function: rudder / elevator / aileron and motor
The Depron components are precisely cut using a CNC machine.
Positions of all adjacent components were also marked and
labeled CNC. This ensures that all adjoining components can be
glued on without any problems. The PVC components were deep
drawn.

The manufacture of all components and the completeness of the
kits were carried out by hand and conscientiously. If you notice
inaccuracies of 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 DEPRON building material is a very light building material that
is normally used in house construction. In hardware stores it can
be found in wallpaper departments under the name "Unter
Wallpaper" as an insulating 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 ideally suited for the construction of "slow flyers"
up to weight classes of well over 3 kg. Depron has had a justified
place in the model flight sky for many years reached.
Depron processing:
Depron can be deformed cold with the ball of the hand over the
edge of a table. The sanding of corners and protruding edges is
easy to do with fine sandpaper. When cutting Depron you should
use a sharp utility knife with a narrow blade. UHU-Por is very
suitable for bonding Depron-Depron, unless it is under tension
during bonding, or in connection with other materials, or the bond
is subjected to a higher load. You use the tried and tested water-
based epoxy resin or white glue. "Modeling filler" from "Moldofil"
from the hardware store is ideal for filling gaps and unevenness.
The paste, similar to toothpaste, can be smoothed into the Depron
gap very easily and after hardening is hardly harder than Depron.
necessary building materials:
All the necessary Depron components can be found in the Depron
parts set. All additional necessary building materials such as
stiffening materials (CFRP, wood etc.) or adhesives or RC
components are not included!
In addition, PVC components such as: canopy, engine hood and
the spinner are included in the kit.

Wing:
Assembling the Heling
Prepare wing parts T1 to T4. To do this, place the wing T1 and T2
on the heling and lightly grind the glue joint until they fit together
without a gap.

Use a 6 X 0.5 mm or 8 X 0.5 mm carbon flat bar to reinforce the
wing. To do this, cut into the marking along the wing so that the
carbon rod can be inserted without play. The flat bar should be
flush with the underside of the wing. Cut the carbon rod to length
so that there is enough adhesive surface available to bond both
sufficiently. Since the overhang under the wing is within the skin,
it is not
visible.

Adjust the upper parts of the wing (caron rod may need more
space in the Depron) and sand the glue joint. Do not stick on
yet!

Insert the ailerons using the hinges.

Prepare the aileron servos. Extend the servo cable until the
connectors reach sufficiently into the fuselage area. Adjust the
servos to neutral and glue them flush to the bottom of the lower
wing.
Cut a cable duct into the lower and upper wing. It is sufficient
to notch a "V" with the craft knife. This can lead along the
carbon spar. Cut an opening through the upper part of the wing
so that the cables can be led out upwards.

Glue on the upper wing.
Sand the leading edge: Like every profile, sand the leading edge
up to 2/3 and down to 1/3. The KF step must remain
sharp!

Fuselage:
Insert frames S1 to S6 into the trunk stringer R1 starting from
the rear and glue them flush with R1. S1 is in two parts.

Now the longitudinal stringers R2 can be pushed in sideways,
aligned and glued.
Now insert R3 and R4 according to the drawing and glue them
together. The top edge of R4 should be flush with R1.

Now sand all components together so that the planking will
later lie flat on the joints.
Let the tail run out to a
point.

Preparation of the first hull paneling.
Marking must be inside. Carefully pull the planking over the edge
of the table with the ball of your hand until the radius of the trunk
is approx. Do not pull immediately with too much pressure so that
the Depron does not break. It is best to slowly approach the
bending radius.

The planking should be pre-milled as far as:

Place the fuselage in the sheeting. The marking of the adhesive
surfaces is an orientation, the material overhang does not allow
the planking to be perfectly aligned. Excess material is trimmed
later. The bonding can be done with z-b. UHU POR take place.
To do this, coat both components, place baking paper between
them (UHU POR does not stick together), align the body and
pull out the baking paper piece by piece. The bonding can of
course be done in stages, also with other adhesives. The
planking should be glued over the middle of the fuselage.
