I flew the R22 a few times, and did not like it. I had previously flown the 300 and liked it, and when a local school made two available for training, I earned my license on them. A much superior helicopter to fly in my opinion.
I was aware though that they were more demanding for maintenance (as I would see them off line). But they are a different type of helicopter too.
I was certain that I saw a Guimbal flying in Victoria YYJ last August.
