I hope the regular reader(s) of this column will forgive my first-quarter dalliance with twin-engine aircraft. This month we get back to singles.
The Avia B-135 was the follow-on to the fixed-gear B-35. Though a contemporary of the Spitfire, and roughly parallel to its development, the Avia fighter never reached the production numbers or wide usage of Supermarine's masterpiece.
The B-135 did possess reasonable performance but, within its limited employ, did not see enough use to develop into a potent fighting machine. It was powered by a troublesome 860 HP in-line engine and carried two machine guns and one 20mm cannon. While lower-powered than the early Spitfires it also weighed quite a bit less so the power-to-weight ration was very roughly equal to start (though it certainly did not remain so as the Spitfire developed). That could be one major difference between the production of twelve aircraft versus 20,000+.
An interesting aircraft with the looks of a racer, and one engine.
