but I think it's one of the main reasons why I hate G-Forces and don't trust airplanes at all.
But then it was not the aircraft that let you down - in spite of the instructor the aircraft held together and kept you safe!
I would agree with those that say if you want to spin train go for an aircraft that is more suited to it, but that is only because it will spin better, the Cessna spin tends to decay into a spiral too easily. As far as Markkals comments about precautions go (take a G meter etc), this really is not neccessary IMHO, as myself and others have already pointed out recovery should not go anywhere near the aircraft limits.
