jeeze he was doing 60 degree turns, thats harsh, I know it depends on the AC but the most I ever really worked out in or had to do was 45, I'm sure its because of the plane..... I have ridden many many many times through stalls as my CFI was showing me proper procedure over and over again and then me doing it. The first few times I was doing the power off stalls, I was forgetting about carb heat and I wasn't looking at my ball ( big mistake in a stall ) so basically every time we would go up for a lesson we would go through it again and again, if I was doing them sloppy he would grab the controls and get me sharp again, you can definately feel the buffet more in a power on stall IMO, I've done so dang many of em I can almost predict when the nose will start to pitch over based on how many shakes there is, generally 3 right as it stalls, a little bump bump bump... Power on stalls were way easier for me to get the hang of in the begining, less procedure, basically just keep that ball centered and just release the pressure when it stalls... My main problem when learning that plane was doing 45 degree S turns and spot turning while keeping the plane at the same alt, my CFI said it was because I'm used to flight sims and not actually looking at the real horizon and the surroundings, so I had to fly for a long time with the stupid inverted plastic thing on my head so I couldn't look at my instuments, that was the absolute toughest for me, but after a while I got the feel of when the plane is pitching or yawing.
