20.
Locate the two remaining control horns and cut two lengths of 18swg wire to 65mm long to make two
aileron control rods. If using control rod connectors drill out the holes on the control horns to 2mm Then pass
the rods through each of the control rod connectors and insert the control horns into the slots on the underside
of the ailerons and stick them into place.
21.
Level the ailerons and tighten the screw on the control rod connectors. It is suggested that thread lock is
used to secure the screws.
22.
Carefully trim the vacuum formed canopy to fit. The rear of the canopy fits to former ‘F8’.
If required mask off the canopy framing and paint the frames. Stick the canopy in place using either ‘canopy
glue’ or a ‘non-fogging’ Cyano glue. Do not use ordinary Cyano as it will cause the canopy to fog. It is
suggested that the glue chosen is tested on the trimmings from the canopy before using.
23.
Exhaust stacks. The exhaust stacks are made by first laminating three exhaust parts from sheet 9 together.
If required sand each exhaust pipe to a rounded profile. These can then be painted before the top and bottom
plywood pieces from sheet 10 are stuck into place with the narrow end facing towards the front of the stack.
The top and bottom pieces are usually the same colour as the fuselage area to which they are stuck to.
On each side remove the covering from the square slot on each side of the fuselage nose (approximately
52mm from the front and 28mm from the bottom of the fuselage side) and stick into place.
24.
Remove the covering from the four holes at the front and rear of the wing saddle. Cut two pieces of
1
/
8th
dowel to a length of 4 inches (100mm) and insert them into the holes so that the dowel has an equal amount
(16.5mm) on each side of the fuselage and secure in place with CA.
‘Xtra Detail Sheet 11’
1.
The
‘Xtra Detail Sheet 11’
supplies some extra detail that can be added to the basic Bf109 kit.
2.
The sheet includes parts for the addition of the ‘chin’ radiator on the fuselage and the two under wing
radiators and the air intake which is situated on the left-hand side of the fuselage.
3.
The chin radiator is made up of four parts. A base with two slots, two radiator sides and underside sheeting.
Stick the radiator’s base onto the underside of the fuselage immediately ahead of the wing seat (in place of the
part supplied with the basic model). With this in place insert the two side parts (do not apply glue) into the slots
and stick the radiator underside sheeting to the side parts – be careful not to stick the radiator to the fuselage
at this point. Remove the assembled chin radiator and cover it. Stick into place once the fuselage has been
covered.
4.
Each wing radiator is comprises of 6 pieces, two base parts, two sides, one underside sheet and a rear
sheet part. The base parts are added to the wing as described at
step 13
in the
Wing Construction
section.
Insert two radiator sides into the base slots noting that the radiator side with the notch at the rear fits into the
slot nearest the wing centre line. Stick the radiator sheeting to the sides ensuring that the radiator parts do not
get stuck to the wing. Remove the completed radiators and cover. Stick the radiators into place once the wing
has been covered. The remaining radiator parts should be covered and then stuck to the wing trailing edge
directly behind and ‘butting up’ against the rear of the wing radiators. If required the rear sheet part can be
‘relieved’ to fit over the plywood TE doubler to achieve a better fit/finish before being stuck into place.
5.
The air intake is made by laminating the four parts together. Sand the intake to a rounded profile and cover.
To position the air intake, make a small vertical mark 32mm from the front of the wing seat towards the rear
and in-line with the motor shaft. Then make a horizontal mark to intersect with the first in-line with the motor
shaft centre line. The air intake should be then positioned with its bottom rear corner resting on that mark.
Remove a small amount of covering where the air intake base sits and stick into position ensuring that it is
horizontal.
