What is "aircraft stability" - IN VIDEO

[Crumpp]

The Hurricane has unusual apparent longitudinal static stability characteristics (pitch trim change with speed). Depending on the c.g. position and the type of propeller fitted it varies from slightly stable to slightly unstable.

I have no idea what variant or set up of the Hurricane Dave Southwood is refering too here.

It is a fact, the Hurricane Mk I as it was used in service of the RAF during the Battle of Britain, was stable and near perfect in its longitudinal stability and control.

I love this part:

As a final thought, please note that it is easy to concentrate on the deficiencies of an aircraft and gloss over its other possibly excellent characteristics. The fact that the Spitfire has poor control force harmonisation and is easy to tip on its nose does not detract from its outstanding turn performance, superb low IAS and high Mach number controllability, and benign stall characteristics. It is a very charismatic and pleasant aircraft to fly overall. And the challenge of trying to master the Bf109 on take-off and landing makes it a very satisfying machine to fly once you have gained some confidence in it.

All the pilots loved the machine that took them home.

Myopically, some see modeling flying qualities as an attack or effort to "pork" their gameshape.
