I did a BFR once with an ex-Navy guy in a 172 out of RYY. Very unlike any other instructor I've ever flown with. All the others were clearly taught being groomed for the airlines....all about smooth. No airsickness here......
This guy was like
Cessna 123, turn left heading 090...Bam, yoke hard left, instant 30 degree bank angle, hard back to center to maintain the bank....reaching the new heading, Bang.... yoke hard right, instant wings level...boom, yoke neutral.
He was very jerky...but extremely precise....no flying 089 degrees...it was 090.
Honestly I wish I'd have had a chance to fly with him more.
