Dornier Do328 Turboprop - low speed directional stability

[212man]

I am looking for information on the directional stability characteristics of the Do328 TP at low air/groundspeeds, whilst using reverse thrust. The AFM has a caution about reverting to ground idle by 60 KIAS, or earlier if directional control issues appear, but are there any ex-328 TPs, TCs or SFIs (or regular line pilots) that can give more details? Is it prone to rudder blanking, for instance?

The AFM caution about "reverting to ground idle by 60 KIAS" is probably due to avoiding dust/ foreign object ingestion into the engine.

What is Vmcg for the 328?
