Had the BFR yesterday. The turning stalls were a non-event - thanks to your replies and the CFI's demeanor - and the 172 is pretty docile.
turns out the CFI flew Helos for awhile, then was XO at two training squadrons: VT-2 and one I can't remember flying the T2 and T6. Very laid back training style: "Hey, I think I smell something electrical burning, what should we do"?
Flight started with a simulated engine failure during departure after turning crosswind. Made a beeline for the runway and landed opposite direction, then out to the practice area for the steep turn, slow/stall (with turns) series and then some unusual attitudes at my request. Shot the localizer into the home field, then 3 more t/gos with varying flap settings.
Great flight.
