Agreed, especially the 3rd. para. I think it fair to say all pilots who have flown T-Tails give extra care and attention to rudder handling. You want to look after your empenage 'cos there ain't a lot you can do without it! I cannot think of a valid reason for rudder reversal. Certainly not rapid, ever! If you push wrong rudder on in an engine failure scenario, then pushing it the other way is the only conceivable time. The change in sideslip will have to be very carefully handled, even doing it slowly.
The lessons have now been learned........haven't they?
