As a private venture two prototypes were begun as a modification of the Sopwith Camel to use the heavier 150hp AR.1. The first prototype Snipe single bay wings (later became B9962), powered by a Bentley AR.1 (Admiralty Rotary type 1) later just known as BR.1 was completed in October 1917. The second prototype (later became B9963) was completed with a rounded fuselage and the new, more powerful Bentley rotary, which gave 230 horsepower (170 kW) on 23 November 1917. Initially it had single bay wings but, later modified to dual bay wings. At that time these still employed the unbalanced ailerons.
When the Admiralty became interested in the private venture they issued contract A.S. 316688/17 in April 1917 it included six prototypes B9962-9967. Three of these were ordered to use the 230hp B.R. 2. One further variation of the prototypes was B9967 had a Dragonfly radial as a power plant.
The third prototype B9965 had lengthened wings, with a wider centre-section and a smaller cut-out for the pilot, while the fuselage had a fully circular section, rather than the slab-sided one of the first prototype, and the tail was smaller. It was officially tested in December 1917, reaching a speed of 119 mph (192 km/h), and was then rebuilt with longer-span (30 ft (9.14 m)) two-bay wings (compared with the early 25 ft 9 in (7.85 m) single bay wings. This allowed the Snipe to compete for Air Board Specification A.1(a) for a high-altitude single seat fighter. This specification required a speed of at least 135 mph (225 km/h) at 15,000 ft (4,573 m) and a ceiling of at least 25,000 ft (7,620 m) while carrying an armament of two fixed and one swiveling machine gun. An oxygen supply and heated clothing were to be provided for the pilot to aid operations at higher altitude. Tail units were modified from the original design progressively to enlarge their overall areas. Ultimately these were similar to the contemporary Sopwith Dolphin tail units in profile.
The kit comes in a typical Wingnut Wings two part open top box. Artwork on the box and the comprehensive instruction monograph is their usual high grade. The cost is $69.00 with free shipping.

Step 1, Cockpit build begins with the petrol tank & floor boards (PP A 19 & 36), rudder bar (PP A 6) stabilizer board (PP A 13). The fuselage structure (PP A 17) and fuel tank pressurizing pump (PP A 14). Next is the control column (PP A 22). The instrument board / ammunition storage facade (PP A 27) has a series of instruments & gauges moulded to the front and the their faces are represented by decals. Their placements are detailed here, along with the choice of tachometer (PP A 9 or 10). Next is the pilot’s left fuselage interior (PP A 18) and you add the throttle & petrol (PP A 8) unit. The pilot’s seat is depicted as wicker (PP A 25) with the typical leather wraps and a cushion (PP A 30). The only issue here is that the wicker does not open at the back face of the seat. The solid band can be trimmed away for an scale effect, as shown on in the Hints & Tips on WNW's website
. Yet when it comes to the structural sidewalls (PP A 17 & 18) impressively come as one whole mouldings.
Step 2, Cockpit continued detailed the rear gun mounts & adjustable tail lever (PP A 15), additional rib structures (PP D 3 X 2), compass (PP A 3). Air speed indicator (PP A 2) and the firewall (PP A 28). Next is the Vickers machine guns (PP D 15 & 16 X 2 , PE 1 & 3 X 2) next add the ammunition feed (PP A 26) and the empty link chutes (PP D 10 X 2).
Page 5, Cockpit painting & rigging guide is next. This of course should be thoroughly referenced early in the build.
Page 6, Colour shots of TVAL modern reproduction gives you a good perspective of the finished 1:1 build.
Step 3, Fuselage (interior) & painting and add the facades for the carburetor intakes.
Step 4, upper decking & lower wings Note here the upper decking interior (PP F 2) is both metal & wood ply. The support former (PP A 11) is shown as plywood coloured. Note the placement of the Sutton Farm shoulder straps (PE 8 X 2) to the support former (PP A 11). Note you should drill the recommended holes in the lower wing (PP B 4) roots for the cooper bomb racks if you intend on installing it later.
Step 5, 230hp Bentley B.R.2 Engine (PP E 1, 2, 3, 4, 5, 6, 7 & 8). “The initial variant of the B.R.2 developed 230 horsepower (170 kW), with nine cylinders measuring 5.5 by 7.1 inches (140 mm × 180 mm) for a total displacement of 1,522 cubic inches (24.9 L). It weighed 490 pounds (220 kg), only 93 pounds (42 kg) more than the B.R.1. . .” The B.R.2 at the 245hp rating appears to be the pinnacle of rotary engine development for the British. The wiring diagram is a bit small for modelers and I recommend the use of an “Optivisor”.
Step 6, Cabane & interplane struts come as individuals and I recommend a “Lego” block jig to align them for the addition of the top wing panels to come next. There is also a ring and bead sight (PE 2 & 4) scrap view.
Step 7, Top wing (PP B 3) attachments include a fillet (PP A 7) or “Aldis” sight bracket (PP A 34). I would recommend adding the “Aldis” sight (PP A 31) next and not as the instructions state in step 9. Set the lower wing ailerons (PP B 2 X 2 & D 5 X2) next. I would pin them in place with brass rod / wire.
Step 8, Undercarriage parts are assembled here. The setup is typical for Sopwith aircraft of the time. The undercarriage legs (PP A 35 & 38) spreader bar / axle (PP A 16), wheels (PP D 7 X 2), retainer rings (PP D 6 X 2) and wheel covers (PP D 11 X 2).
Step 9, Final assembly brings the propeller (PP A A 41 & F 3), bomb carriage (PP A 23 & 24), Cooper bombs (PP D 13 X 4, D 14 X 4), Upper wing ailerons (PP G 4 X 2 & D 5 X 2) together. Then the tail unit adds the control, horns (PP D 4 X 4), vertical fin (PP G 1) and rudder (PP G 2 & A 1).
