Well, it is as you say a fascinating matter. The ground steering system on the Chipmunk involves applying a couple of notches of brake and the using differential braking, but of course with such brakes applied one cannot select full rudder and the Chippy, for all her benign manners, will not recover from a developed spin without full rudder. This item on the RAF checklist became, for some reason, common currency in aeroplanes which have no such brake/rudder issues.

So now you know.
