Thank you! This answers a lot of mysteries for me!
That's also why ailerons are more effective in a stall when stalled with flaps out.
Actual best sustained turn speeds need to be flight tested but you generally don't need the actual best speed as long as you're close.
Thanks, FLS. I didn't know this. I'm just going by feel.
The biggest thing I notice about my flying is the lack of coordinated turns when slow.
Just push left foot when you roll left, right foot with right roll, center pedals as soon as you get the bank angle, you generally don't hold the pedal for the turn but you may need a little correction. Make it a habit and don't worry about getting the ball exactly centered.
Keep in mind uncoordinated flight is harder to hit.
