The instructions begin with assembling parts for Roden’s 200hp Wolseley W.4a “Viper”. Note the parts map shows parts for the 200 - 220hp Hispano- Suiza engine are on the same tree. But in truth they were gated out. To explain, molds have small gates that allow for certain parts to not be filled with styrene when poured.
Step 1.) Following the instructions, the two cylinder banks (12 & 13 E ) & ( 17 & 18 E ) have the camshaft drive housings attached to the rear of each bank of four cylinders. The valve covers are represented well and the modeler only needs to erase the union seams of the halves. The camshaft drive needs to be cut down slihtly some mating halves join correctly.
Step 2.) The carburetor assembly has the water/ / condensation drains ( 7 E X 4), these could benefit from some PE pieces if someone were to make them. The intake manifold arms (11 E X 2) go from the cylinder bank inner faces to the carburetor and intake manifold base (15, 18, 20 & 21 E ). The whole assembly will hang in the open area between the finished cylinder banks.
Step 3.) The twin magneto assemblies ( 14, 19, 22, & 23 E X 2 ) will attach to the rear of the crankcase on horizontal flanges.
Step 4.) Unites steps 1-3 with crankcase assembly (1, 2, 3, 4, 10, 24, 27, 28, 29 E) and crank shaft end ( 40 C ). The magnetos from step 3 have a conduit (24 E )filled with wiring that runs between them. The wiring leads are represented by 14 E on the magnetos. The oil scavenging pump (28 E ) mounts to the rear and the water pump (29 E ) mounts to the underside respectively of the completed crankcase ( 2 & 3 E). Spark plug wiring needs to be duplicated to further detail this fine mold. The air pump (10 E ) and the oil filler tube (27 E ) are added to their locations.
Step 5.) Attaches plumbing to the underside of the crankcase for oil lines (5 & 9 E ) & water lines (8 E X 2 and 25 E X 2). Note there are two nipples one each on the rear of the cylinder banks valve covers. On the pilot’s left is the tachometer gauge connection. On the right is the Vickers machine gun synchronization connection.
