The DH-60 Moth was a nice aeroplane and became the DH-60T for the RAF. However, exit from the front cockpit with a parachute was tricky, hence the shift forward of the upper wings with sweep back to maintain the C of G - the lower wings have slightly different sweep to adjust the C of G slightly.
Also the inverted Gipsy Major came into the story somewhere and the whole lot became the DH-82. A few detail differences led to the DH-82A - the main one was an increase in dihedral of the lower wings to improve ground clearance by shortening the interplane struts.
The whole lot was done by modifying a DH-60T, sawing off bits of spar here and there, back of a fag packet stuff!
Read the Tiger Moth Story by Bransom and Birch - good stuff!
It's not really that bad an aeroplane is it? A challenge to fly well perhaps? Some people seem to love them...
