FWIW.....
After liftoff and positive rate, I raise the gear and pitch for 5 deg with the VVI, flight path marker, whatever you care to call it. Accelerating through 180KIAS, I will raise the flaps.
IRL, on the civilian side, we climb to a predefined altitude at a predetermined pitch to acceleration alt. (Typically 1000 feet AFE) before cleaning up but I'm not sure how real Hog Drivers execute that.
I'm sure that with the stable of knowledgeable blokes that we have here, someone can shed some light upon the acceleration altitude the the USAF uses for the Hog.
