Send Clowns,
You stated you could teach me "what can be done by way of angle of descent with sideslip but little flap".
Also you stated "KEEP THE SPEED UP"
I fly into very short strips every week and the reason I sideslip is to "decend steeply over the shortest distance"
I must fly the aircraft at the minimum approach speed to achieve this, and the minimum speed is achived with full flap on most a/c with few exceptions.
I have 53 aircraft type logged and most fly the same.
HWD, you state "Apparently, low-wing aircraft are also generally unstable in the side-slip"
This is just NOT TRUE
