I realise you didn't ask for this, but I'm bored ;-)
Yeah, I've looped the A150 hundreds of times, and I realize it's a compromise aerobatic plane, but, it's what I had to fly... One day, I took the owner's son, a very new pilot, for some planned aerobatics. I briefed the loop. I was just pulling through the vertical, and everything was perfect, to feel a swift push on the control wheel, as he said: "I don't think I like this...". He liked what happened next a lot less than he would have liked the loop! I'm glad that the Aerobat is also well stressed negative! The next loop I flew for him was only my effort, and much better all the way around! He is now a very well known aerobatic airshow pilot - flying a
real aerobatic plane. I'm not sure what it is, other than it's a green biplane, painted in reptile scales. He can far out aerobat me now, and he's welcomed to it (I'm too old for that stuff now!).
