De Havilland Hornet Moth

Cabin biplane, designed as trainer and touring aircraft. During WWII the RAF used a few as liaison aircraft.

The original Hornet Moth was built with tapering wings, but these were found to cause problems especially when landing in three-point attitude when there was a tendency for the tips to stall, causing embarrassment to the pilot and quite often damage to the aeroplane. De Havilland offered owners of the DH87a replacement wings of the new squarer shape at a reduced price in exchange for the original wings.
