Question min. radius vs max. rate turns

Entering a max rate turn, we teach full power and pull to the start of the stall warning or just before the start of the buffet. This gives the best rate of turn by providing the most lifting force you can get from the wing at the time (the reason for the stall warning), without the induced drag slowing you down too much (the reason for the power).

Questions.

1) Does adding flap increase the rate? It certainly gives more lift, but the drag increase would, I think, nullify or override any gains there, and you wouldn't be able to roll in as far, and not pull as hard.

2) Does an increase in power available increase the rate if you are pulling at the stall anyway? As far as I can tell it would have to increase the lift from the wings...

1b) What about effect of flap on radius? I think it would decrease the radius simply because of the resulting slower speed.

3) I think in the USA you teach min. radius turns, what's the recipe for one of those?

4) How does all this fit into the v-g diagram?

From a "studying too hard" instructor (me). Got too many words in my head at the moment! I could read "Aerodynamics for Naval Aviators" again, but it wouldn't make any more sense even though it is a GOOD book :frown:.
