When the load factors go up, so does the stall speed. Most have an understanding of this.
But did you know that in a 45 degree turn the stall speed goes up with over 40%? That's quite a lot. So, if you're low, heavy, have marginal speed already and gusty winds, it is imperative that you increase your speed either with throttle or by pushing nose down when you turn. There is nothing dangerous with a steep turn down low as long as you protect your speed. Or even better, install a cheap AOA meter and take the guesswork out of it.
