It is said that the de Havilland DHC-1 Chipmunk looks the way an airplane should look.

It also has that distinctively shaped vertical fin, the signature of many de Havilland designs (including the D.H.98 Mosquito fighter/bomber).

As the propeller ticks to a stop, a new Chipmunk pilot usually just sits in the cockpit for a while wearing a smile that reveals his infatuation. The Chippie engenders that kind of affection from those lucky enough to fly one.

TB
Over the years and locations of fabrication some of the Chipmunk specifications have varied.
The gross weight has changed.
The recommended speed for various aerobatics have changed.
Some were not equipped with electric starters and some were.
The positive and negative G ratings have changed.
I think the above specs are typical of the most recent production.
