I find with my PIK that my pull ups are much better with the flaps
full negative until I get below 65 kts. I then slowly transition them
to +8 if I'm going to circle, but only to 0 if I'm going to pass
through the lift and go on. It seems that I waste less time and energy
if I go ahead and transition back to -8 as I nose over to go on. I've
often wondered if I'm doing this correctly, but it seems to work.
