How to build BAC111-500

BAC 111-500

 

 

This topic should replace the missing construction sheet for the 72airliners BAC111 kits.

I will discuss the progress by aircraft sections, beginning with the engines.



The engines are probably the easiest parts, and can be build straight forward.

Parts 7,8 and 9 are for the left, while parts 10,11 and 12 are for the right engine.

If you decide to use the original engines, you`ll need only parts 7,8,10 and 11.


All others are for the hush kit option.

 

 




 

 


Next step is the landing gear, much more extensive.


The landing gear consists of the following pieces:

 




Parts 20,21 and 22 are the resin landing gear struts which you may substitute by the white metal parts

in the lower right corner of the picture.


For the left main gear, you will need parts 22,26,29,32,33 and for the right gear 21, 27,28,30,31.


Parts 23,24 and 25 are common for either side.

 


Next pictures shows all parts for the left main gear and nose gear separately

( I am using the white metal gear struts ):

 



The forward support strut, part 26, 



and the forward torsion link, part 24 and the aft torsion link,

part 25 assembled to the left main gear strut.


 


I have then added some wiring, but this is an option and not part of the kit.

Now a few hints for the nose gear.


The steering unit consists of parts 36 and 37. Both pieces must be inserted through their holes from the top of the nose gear strut down to the stop, which is about in the middle of the strut.

Either piece up or down, but make sure to get the cylinders facing forward and symmetrically angled. See the following 2 pictures:



 


The landing gear is now ready for assembly to the wings and fuselage.

This and the use of the gear doors will be discussed later.



 

 

 

 

Now the most important part of any kit, the fuselage.


My favorite livery is BEA. I have chosen the speed flag livery using the authentic decal sheet.
 

The fuselage itself consists of a main fuselage part, a tailcone and a clear cockpit canopy,

plus a basic cockpit interior.


The biggest disadvantage of resin kits is the attrition of the used materials.


It is very difficult to control it, as it varies with mixture, temperature and mold applications.


This means, a little bit of careful adjustments are required

to get a good fit of the tailcone and the clear cockpit pieces.

As the decal sheet shows passengers already on board, I decided to man the cockpit as well.



After completing the cockpit interior, I inserted the clear cockpit piece.


After filling and sanding the seams, I covered the windows with bare metal foil.

The window frames are clearly visible and can be cut out carefully.



This is how she looks so far:


 

 

 

To assemble the tailplane, you`ll need parts 13,15,16,17 and all unnumbered parts.

See the next picture.

Shown here is the revised design with stabilizer and separate elevators.

Early editions have a single piece unit




Parts 15 and 16 are the aerials for the left and right side of the vertical fin.

Part15 is the top and part 16 the lower one.


Two small dents on both sides of the fin indicates where to insert these aerials.

 




Before painting the stabilizer, I glued on the elevators and the nose cone and cut off the tip of the stabilizer fairing.

I replaced it with a clear piece, which is not part of the kit.


I have replaced the thin and brittle resin pitots, parts 13, with brass tubes.

They were inserted into the holes of the nose cone.


Another antenna, part 17, will later be assembled on top of the fairing.

This is not common to all aircraft, however.
 

The basic colors for the fin and stabilizer where airbrushed,

while the speed jack logos and the metal leading edges are from the decal sheet.

 


 

 

 

 

Here are all parts you`ll need to complete the wings:

 




Unfortunately, the molding company forgot to number the flap fairings.

I marked the sprues accordingly, numbered from left, #1 to right, #6.


Obviously, the thickness of the wings is reduced slightly during the molding / casting process.

To get a proper fit to the fuselage, you`ll have to fatten the fitting pins.

I used 3 stripes of 0,25mm styrene, as shown in this picture.

 


 

 

 

The wings have been completed now.

 


After airbrushing the basic color, I added the metallic leading edges from the decal sheet,

the small clear nav lights and the leading edge fences.


The nav lights were brushed with red and green clear paint accordingly.

 




 

The thinner ( than the master ) wings also causes a problem for the leading edge fences.


Their gaps between the upper and lower halves are fitting the master,

but are now a bit to big.


I solved this problem by cutting a small dent,

as shown below,

by using a razor blade saw.

Then both halves were glued together with super glue

and eventually any residual resin was sanded off.



 

 

 

Now, I finished the main landing gear.


To put the main gear into place,

insert it into the forward facing hole,

then push it down into the aft bearing,

as shown in the next 2 pictures for the left main gear.





 

The following pictures shows the right main gear.


Parts 23, similar for both main gears,

and part 27, 26 for the left side,

shall be assembled as illustrated on the next 2 pictures.





 

The main landing gear doors will be next.

 

The main gear doors consists of the outer doors parts 30 and 32

plus the inner doors parts 28 and 29.

Parts 28 and 30 are for the right hand gear.


The outer doors should be inserted with their hinges between

the landing gear struts and the outboard facing wall of the wheel wells,

while the inner doors should be glued onto the main gear struts

and the pintles of the forward support beam.

 


 

 

 

The nose gear doors are parts 34.

They should be build in at an angle of about 30 degrees.


I added actuator rods using very thin brass tubes. These are not part of the kit.



 


Here is how it looks with the nose gear in place.




The last step before final assembly is the ventral stair.


These are the parts you`ll need for it.




 

The handrail with the little pintle and the actuator for the fold in mechanism

of the last 2 steps shall be placed on the right side of the stairs,

see the next 2 pictures.



 

 

 

After adding some more antennas,
please check the particular aircraft you are going to build for these details,
and a little bit of weathering she is finished.
