Did some flying in one at Hurn (group plane parked @ AA). As with all B products. Well build and sturdy, especially undercart on these. But for the HP up front, SLOW and needs to be flown on the black stuff more so than other offerings.
Interesting point on that one was the wing spar. I think it only had less than 2000 hrs on the airframe, but needed replacement due to corrosion. All panels glued in place, aparently a first type of this job for the AA boys and the Cof A still only came to about £ 6k ?.
Anyway I'd rather fly a AA5B for my 180hp Lycoming's fixed pitch worth.
