Hi all, The 'Lang' propeller is wood laminated from 'ProperPlane' and was airbrushed with a 'Tamiya' clear orange and Hull Red mix, to create a darker and varnished appearance. The machine guns are from 'Gaspatch' and were modified to add a 'ring' gun sight and alter the angle of the cocking handles, , Mike

Hi all, The fuselage is closed up now. I've added twin trigger cables and the 'blip' switch cable to the control column. Also the seat belts, cockpit cross beam and the fuel pressure pipe from the pilot's hand pump to the fuel tank.. As usual not much can be seen, although the cockpit on the 'Swallow' is more open than most, but the low wing cover a lot. Now it's onto filling and profiling the external fuselage. Mike

Hi all, I've been working away at the cockpit area, which is just about ready for closing up the fuselage. All of the flight controls, except ailerons, have been added along with the visible cross bracing on the cockpit side frames. I still have to seal the area and gloss the instruments. Also fit the pilot's seat straps, gun trigger cables and fuel tank pressurisation pipe, but they will be done after the fuselage has been closed up, Mike

Hi all, I'm currently working on the internal rigging. Here's the flight controls consisting 'Gaspatch' 1:48th scale turnbuckles (Type A and C), 0.4 mm diameter Nickel-Silver tube and 'Stroft' 0.08 mm diameter mono-filament. The rudder bar was drill with 0.2 mm diameter holes to secure the four rudder lines using 0.125 mm diameter copper wire. The elevator pulleys were also drilled through to accept the elevator line. A short piece of tube was secured to the control column to act as the attachment for the elevator forward cables. The floor under the pilots foot boards has cross-bracing added. Only the ailerons control run is still to fit, but can't be until the fuselage is closed up, due to the way the cable is routed. Next up is the cross-bracing to the cockpit side frames. Mike

Hi all, The engine supplied with the ‘Wingnut Wings’ kit is for the ‘Clerget’ 9B or 9Bf engines. However the last engine type to be fitted to the Sopwith ’Swallow’ was the ‘Le Rhöne’ 9J (110 hp), which is of a different design and copied by Germany as the ‘Oberursel’ Ur.II. Therefore I chose to use as a replacement engine the ‘CMK Master Models’ Le Rhöne 9J (110 hp) - (kit No.129-5105). The most obvious difference in external appearance between the ‘Le Rhöne’ and ‘Clerget’ rotary engines is that the valve push rods were fitted to the rear of the ‘Le Rhöne’ engine cylinders, whereas the ‘Clerget’ engine had these fitted at the front of the cylinders. Also the fuel/air induction pipes on both engine types were located at the rear of the cylinders, but whereas the ‘Clerget’ engine had these pipes connected to the rear of each cylinder head, those on the ‘Le Rhöne’ engine were connected at the side of each cylinder head. The push rods were replaced by 0.4 mm diameter Nickel-Silver tube and the ignition leads were twisted 0.125 mm diameter copper wire. The spark plugs were replaced using 0.5 mm and 0.3 mm diameter brass tube. The propeller boss and back plate were discarded as the I'll be using a wood 'Lang' propeller from 'Proper Plane'. Mike

Hi all, A few more changes required in the cockpit area. 1. Photographs show that the front decking panel had a cut-out on each side alongside the breech blocks of the Vicker's guns. These were filed out. Also the decking panel was filed for clearance around the base of the four cabane struts. 2. The 'Camel' had the main fuel tank behind the pilot's seat and an auxiliary fuel tank above it, which also acted as a wind break, preventing too much airflow entering the rear fuselage as causing pressurisation damage. The 'Swallow' has only one fuel filler cap access aperture in the rear decking panel, indicating there was no auxiliary fuel tank fitted there. As such there would have been a large opening for airflow to enter. As with Fokker aircraft, I assume there may have been a linen wind break fitted above and behind the pilot's head, so that's been added to the inside of the rear decking panel. 3. The pilot's foot boards in the 'Swallow' extended farther forward than those fitted in the 'Camels' and ended just to the rear and below the rudder bar. These were added using 0.5 mm thick plastic card. 4. The 'Camel' aileron control cables were attached to a control lever on the forward end of the control column torque tube. These cables were routed outboard into the lower wing. However the 'Swallow' control cables appear to have been attached to the control column then routed outboard and into box section covers on the pilot's foot boards. From there the cables were routed around pulleys then vertically up and out of the cockpit into the underside of the wing centre section. These box sections were made from scrape photo-etch sheet. Hopefully I be able to actually start painting soon, Mike

Hi all, The four stubby cabane struts are done. I first drilled into the fuselage and cockpit side frames, at the appropriate angles, and fitted 0.8 mm diameter brass rod. Then I created the outer coverings from 1.6 mm diameter brass tube (formed into aerofoil profile) and secured them onto the support rods using CA adhesive. Much stronger than the conversion set resin struts. Both the cabane struts and over wing pylon assembly are located in the four holes drilled through the wing. Mike

Forgot to add the cable retainer to the top of the pylon assembly, Mike

Hi all, The cockpit is more or less ready for painting. I've also made a brass tube/rod over wing cable support pylon, as the resin conversion struts are way too weak, especially as they don't have internal wire support, Mike

Hi all, Working now on modifying the forward fuselage details, which again are different to the 'Camel'. The changes involve: Removing the ammunition ejector ports on the fuselage forward panel. Removing and filling the carburettor intake aperture on the fuselage forward panel. Removing the fuselage panel detail - oval access panel, forward to rear panel joint, rear panel vertical ‘nail’ rows. Removing existing elevator control line access points at the rear of the fuselage. Removing the angled area at the bottom of the forward panel. Re-scribe the angled panel line at the lower front of the forward panel. Re-scribe the vertical joint between the rear and forward panels (further rearwards). Drilling out the new elevator control line access points at the correct positions. Creating new carburretor intakes at the correct position. The lower wing centre section can't be filled and profiled until the fuselage is closed up. Mike

Thanks Harv - getting there slowly, Mike

Hi all, Well things are getting a bit cramped inside the cockpit now. After a fair bit of cutting, sanding and modifying, all of the cockpit main assemblies are done. The shot below shows it all loosely in place, including the two 'Gaspatch' machine guns (the decking still needs modifying to allow the guns to sit vertically). I still have minor detail to add then obviously paint it all etc, as well as modify the outsides of the fuselage, which again are different from the 'Camel', Mike

Hi all, Well I've been working away on modifying the various cockpit parts from the Wingnut 'Camel' kit to that of the 'Swallow' aircraft. The whole cockpit was effectively moved rearwards to improve over wing visibility for the pilot. For the better forward visibility the two machine guns were fitted farther apart than normal. This basically entailed modifying the fuel tank filler cap to the left side, modifying the seat support frame and moving the throttle quadrant assembly rearwards. The control column floor was slightly modified and an extra under shield (from the spares box) was added to bring the rudder bar rearwards. The external fuselage sides are different on the 'Swallow' with the carburretor intakes located in a different position, no ammunition chutes (cut outs in the decking panel instead) and smooth side panels with no 'nail' lines. The centre section of the kit lower wing was cut away to be used as infill under the fuselage (will need re-profiling after fuselage closure). The next step is to modify the instrument panel and ammunition containers assembly so it's located farther back and to allow the two machine guns to locate correctly into it as well as the forward decking panel. Mike

Hi all, I looked further at the decking panels. Missing is the rear of the front decking panel, which should join the rear decking panel. However, this area is where the wing rear support strut should be located, which would account for half of that area. I think this missing area can be filled with modelling putty, once the wing struts and decking panels are finally fitted, later in this build. Mike

Hi all, The resin set is intended for the Hobby Craft/Academy Camel kit, a'though I'm using a Wingnuts kit. The sheets in the resin set state that due to differences in reference drawings, the front decking is too short (for the intended donor kit). Now you can see just how short the length of the resin forward decking panel is, even on the Wingnut fuselage. It's supposed to butt up against the rear decking panel. Onward, upward, Mike

Hi all, Whilst 'working' on the resin front decking panel I spotted an error on both decking panels. The rear decking panel has a pre-moulded fuel tank filler cap, which although in the correct position, is proud of the decking surface. The actual aircraft had, like the Camel', an opening to gain access to the filler cap lower down inside the fuselage. The front decking panel had a filler cap forward and between the gun troughs. However on the resin panel this was just a stump of resin - not sure if it was a mis-mould? Anyway I cut the filler cap from the rear decking panel and drilled out the location (the filler cap on the 'Wingnut Wings' tank will need to be moved to the other side to match). I then drilled out the front decking panel location, filled the hole with modelling putty (from underneath) then inserted the filler cap from the rear panel. So two faults corrected with one filler cap!! Mike

Hi all, It seems the wing had an inspection window for the aileron control cable and pulley, similar to other Sopwith types, such as the Pup, Camel and Snipe. I've cut out the recess at two levels - one for the window and a lower level for the aileron pulley. The aileron pulley was made from the 'HGW Models' photo-etch set for the Sopwith Triplane. The inspection window is a spare from a previous 'Wingnut Wings' Sopwith Pup build. Mike

Hi all, The rear cockpit decking panel was tricky to do, but then I didn't expect it would be easy. Once all of the flash and the mounting block was cut away, I sanded the bottom edges and rear face. The 'Wingnut Wings' kit fuselage was temporarily joined with elastic bands and the shoulder at the rear sanded away as it stopped the resin decking panel from dropping down. I soon found out that, no surprise, the resin decking panel was not wide enough to sit correctly on the fuselage. So I cut the panel down the centre and rejoined them, but with a 1.0 mm thick plastic card insert. Carefully sanded to the decking profile. The front decking panel - that's another story!! Mike

Hi all, Pitot tubes, re-profiled centre section cut-out and wing slots added, Mike

Hi all, I've been looking into how the aileron control cables were connected between the cockpit control and wing. It appears that there were two slots through the wing centre section, above the cockpit. At first I thought these slots were for the aileron control cables, similar to the French Nieuport fighter controls (although they were rod, not cable). However, it seems these slots were not for aileron cables and that in fact cables were routed vertically from the cockpit and into the underside of the wing, just outboard from the wing slots. The resin conversion set has detail of an inspection window in the upper surface of the wing, but does state that there is no photographic evidence for this. I think it's assumed to be there as for the other Sopwith types (Camel, Snipe etc), Mike

Hi Gaz, Actually this aircraft was constructed in mid 1918 and testing went on until May 1919. The twin pitot tubes were similar to the Camel, except set horizontal in the wing leading edge, as opposed to vertically on a wing support strut, Mike

Hi all, Twin pitot tubes added and the centre section cut-out forward edge corrected, Mike

Hi all, Well I've made a start on the resin wing assembly. Needless to say it required filling and sanding. I also strengthened the wing to wing joint, which is a basic 'butt' joint, with no strength. I drilled two 1.0 mm diameter holes into the wing root of both wing halves and inserted 1 mm brass rod, held with CA. The wings halves were then joined using two part epoxy adhesive. I cut the aileron from the wing and profiled the leading edges. The wing was drilled in three position for each aileron and 0.8 mm brass rods inserted with CA adhesive. Corresponding holes were then drilled into the aileron leading edges. Aileron control horns were made from spare photo etch and secured in slot cut into the aileron leading edges. Each horn has a 0.3 mm diameter hole at each end for rigging. Upper surface strengthening ribs, removed during sanding, were replaced with strips of 0.2 mm thick plastic card. I filled the pre-moulded rigging points as they do not align vertically through the wing. These will be drilled later. I still need to re-profile the forward edge of the wing cut-out above the cockpit, which needs to be straighter. Mike

Thanks - yes I think a lot of filling, sanding, scratch building struts etc is coming my way Mike

Hi all, I thought this time around I'd have a crack at building a 1:32 scale model of the Sopwith 'Swallow' monoplane prototype of 1918. In June 1918, the Sopwith Aviation Company designed an unarmed parasol monoplane, based on the Sopwith ‘Camel’. The aircraft was known the Sopwith Monoplane No.1, but was also known as the Sopwith ‘Scooter’ (to scoot was to move around fast). The aircraft was built for the personal use of the ‘Sopwith’ test pilot Harry Hawker and was based on the their current Sopwith ‘Camel’, but with a single wing mounted just above the fuselage, but with limited space between the fuselage and the underside of the wing. The wing was not supported by the then conventional struts and instead was braced by RAF streamlined bracing wires, all of which were attached to the lower fuselage and a pyramid shaped strut assembly above the wing. The ‘Scooter’ was powered by a single 130 hp (97 kW) ‘Clerget’ 9B rotary engine. The ‘Scooter’ was used as a runabout and aerobatic aircraft by Harry Hawker and was able to demonstrate excellent maneuverability. Eventually it was used as the basis for a fighter design, originally known as the Monoplane No.2, and later named the Sopwith ‘Swallow’. Like the ‘Scooter’, the ‘Swallow’ used the fuselage of a ‘Camel’, but it had a larger, slightly swept wing of greater wingspan and area. Like the ‘Scooter’ the wing was mounted above the fuselage, but higher, to allow the pilot to access the two synchronized Vickers machine guns, which were fitted further apart than normal, again to give the pilot better forward visibility. For the same reason the ‘hump’ in the forward cockpit decking (hence the name ‘Camel’) was not used. The engine was also changed to that of a 110 hp (82 kW) ‘Le Rhône’ engine. Also the traditional oval shaped access panels on each side of the forward fuselage were omitted. Twelve strengthening ribs were fitted across the centre section on the upper surface of the wing. The ‘Swallow’ made its maiden flight in October 1918, and was delivered to RAF Martlesham Heath on 28 October 1918 for official testing. One considered role for the ‘Swallow’ was as a shipboard fighter. Engine problems delayed testing of the ‘Swallow’, but even when the engine problems were resolved, the ‘Swallow’ proved to have a lower overall performance than the then ‘Le Rhône’ engine powered ‘Sopwith’ ‘Camel’. Testing of the ‘Swallow’ continued after the cessation of hostilities but by May 1919 all interest in the ‘Swallow’ was dropped. The fate of the ‘Swallow’ is not known, but presumably it was scrapped. However the original ‘Scooter’ remained in use, and was given the civil registration K-135 and later to G-EACZ. In 1921, Harry Hawker purchased and flew the ‘Scooter’. Harry Hawker died on the 12th July 1921 in a flying accident at Hendon, after which the ‘Scooter’ was put into storage. It was refurbished in 1925 and was used for aerobatic displays and for racing until 1927 when it was scrapped. Some time back I purchased the only 1:32 scale conversion set available, which is a resin set intended for the Hobby Craft/Academy Sopwith Camel F.1 kit. However, that model kit left a lot to be desired, as does the resin set. Therefore I'm going to try converting the 'Wingnut Wings' 'Clerget' Camel kit. I know it's an expensive kit to convert but as I'd already had to rob the kit for another project, I thought I might as well use it. It may be just the resin conversion set I received, but it has many problems. The wing halves are warped, the front cockpit decking (according to the instructions) is 7 mm too short in length, the upper support wing struts are not tb used, only as guides for making your own, and there's more flash and surface 'blow holes' the I care to mention. Anyway it'll be another challenge I guess. Here's a few shots to start off with, Mike
