I've never stalled or come close to stalling a plane doing a 45 degree bank
Hence that's why you were happy with 1,500ft for recovery?
Chill mate, I'm sure you can probably handle a 45 turn at 1,500ft fine. BUT, in a past life I have seen the shock on people's faces as they experienced practicing stalls out of turns and the little warning and vicious onset of the stall itself - it is NOT something you want to do at 1,500ft especially if the outer wing stalls... I have also had a previous life maneouvering at those angles of bank regularly around intimidating terrain and wx and in a loaded aeroplane it can become very uncomfortable VERY quickly...
