Throwing some light on rates of turn

[Crumpp]

I believe Crumpp is simply referring to incipient spin occurring upon accelerated stall -- which is apparently happening too easily and viciously (for a 109) since the latest patch.

That is it.

LE slats are the aerodynamic equivilent of training wheels. Putting them at the wing tips like the Bf-109 does not do much for raising anything more than the section co-efficient of lift but it does keep the ailerons responsive, make for very good stall characteristics, and it is one of the best anti-spin devices a designer can use.

The stall characteristics of the Bf-109 are very gentle, controllable, and offers plenty of warning:
