Eduard has issued a four-bladed resin propeller to upgrade the propeller in their SE.5a kit. The upgraded propeller includes resin and photoetch parts with much finer detail than the kit propeller.
The Royal Aircraft Factory SE.5 was introduced in 1917 with a 150 HP V8 Hispano-Suiza 8A engine with two-bladed counter-clockwise (left) rotating propeller. The SE.5a was an improved version of the SE.5 and was one of the fastest fighters of WWI. The SE.5a aircraft was originally produced with a 200 HP Hispano-Suiza 8B gear-driven engine (‘Hisso’), with a counter-clockwise (left) rotating four-bladed propeller. The gear-driven engines proved unreliable, and were quickly replaced with the 200 HP Wolsely Viper direct drive engine with clockwise rotating (right) two-bladed propeller.
