South African Airways DC-7B

History
The DC-7, first flown in May 1953, was basically a stretched longer-
range development of the DC-6B with more powerful Wright Turbo Compound
engines, four-blade propellers, a 40 inch fuselage stretch and additional fuel
capacity. The DC-7 used the DC-6 wing with very minor changes. The
improved DC-7B (1955) had the same dimensions as the DC-7 with a further
increase in fuel capacity.
The DC-7 changes from the DC-6 were:
- four Wright Turbo Compound engines.
- increased fuel capacity on the DC-7 and yet further increased
fuel capacity on the DC-7B
- four-bladed propellers
- a 40 inches fuselage stretch aft of the wing
- a longer and more pointed nose on aircraft fitted with radar
Description of this conversion pack
This conversion pack is for use with the Heller DC-6B kit and consists of
resin parts for the fuselage plug and engines with metal propellers. Saddle tanks
and a non-radar nose are available separately when required.
The conversion is in two parts, the fuselage and the wings, and is suitable
for an experienced modeller.

1 GENERAL
WARNINGS
1 THIS KIT CONTAINS SMALL AND/OR SHARP PARTS. KEEP
THE CONTENTS OF THE KIT AWAY FROM CHILDREN.
2 USE ALL SOLVENTS, PAINTS, FILLERS AND OTHER
MATERIAL IN ACCORDANCE WITH THE
MANUFACTURER’S INSTRUCTION. OBEY ALL SAFETY
WARNINGS.
2 PREPARE THE PARTS OF THE DC-6 KIT
A Cut the fuselage halves as shown in Figure 1.
1 Tape the fuselage halved together,
2 Cut the fuselage behind the wing. The important things are
that the cut is in the parallel section of the fuselage and that
the cuts in the two halves of the fuselage are aligned.
Position the cuts to suit the window pattern of the aircraft
being modelled.
Figure 1
B Modify the wings if necessary as shown in Figure 2. No
modification is necessary unless you are modelling an aircraft of
Pan American or South African Airways. These two airlines had
saddle tanks installed for greater range.
1 To prepare each lower wing, remove the engine alignment
tabs from the front of each nacelle.
2 Remove the nacelles from each upper wing and put a plastic
card filler in the space left where the nacelles are removed.
When completed the upper wing surface should be a smooth
aerofoil surface.

Initial issue - 15 February 2019
The DC-7B aircraft of Pan American Airways
and South African Airways were fitted with
nacelle saddle tanks as used on all DC-7C
aircraft. This gave them extended range.
If modelling aircraft of these airlines, use
TWC72037 - Douglas DC-7B long range fuel
tanks.
The DC-7B aircraft of South African Airways
were not equipped with radar. Consequently, a
shorter, more rounded nose was fitted.
If modelling a South African Airways aircraft,
use TWC72036 - Douglas DC-6/DC-7 non-
radar nose.

3 ASSEMBLE THE ENGINES
A Paint the engine details on the front of each engine core as shown
in Figure 3.
Figure 3
B Assembles the engine as shown in Figure 4.
1 Decide if the gills are to be shown open or closed and use
the appropriate part.
2 The engine core is used to assembles the other three parts.
3 The propeller is not attached at this time.
4 Do steps 3 A thru 3 B 2 again for the other three engines.

4 Assemble the fuselage as shown in Figure 5.
A Fit the window glazing strips in each section of fuselage,
B Cud window apertures in the fuselage plugs (if appropriate).
C Build the fuselage in accordance with the kit instructions for
the flight deck and nose landing gear bay.
D Assemble the fuselage sections and the fuselage plug aft of
the wing, making sure that the fuselage parts are correctly
aligned.
