I think the the leading edge slats deployed more as a function of airspeed amigo. can't remember exactly but i do remember if they deployed asymmetrically you would be in for a helluva ride until they both deployed.

IRT the Tam A4, I would fly her again but not pull as tightly in the turns and see if that helps. float the turn and try to maintain as much energy at the completion of the turn as you began with.

if it doesn't then i would move the CG back a little bit more and try again. highly recommend being as smooth as possible when putting any G on the bird especially horizontally.

additionally, try taking her into a 1/2 loop and as you get near the top increase the G and see what happens. it might depart on you but the question you have to ask is when does it depart controlled flight? at the onset of increased elevator throw or somewhere nearer the last bit of elevator throw? if it does depart then relax the controls, allow the airspeed to increase while going wings level and then slowly add in elevator to fly out of the maneuver. once you get the hang of it she'll tumble with great enthusiasm

ultimately, the key to A4 is being smoooooooooovvvvvvveeeee

good luck but i'd venture to guess you're probably fine. Andy Wurner is flying one with a P70 at Miramar, maybe talk to him about his experiences.

cheers
