Maybe it's me but I got on fine with it (anno 1984). It's very simple alright but then again so is the AS350.. .The only problem I've had with performance is with a sticking bleed valve, something like 98-99%NG on take off with just over 70% indicated torque. The damn things been replaced twice or even three times but still re-occurs now and again. All said and done, nice to fly and damn reliable, I like it. My favorite version is the BA, faster than a B and a B2 but with a miserable intercom system.
