I see lots of posts complaining about lack of sideslip drag. While I agree there is a major problem with the lift, there is plenty of drag. Take the P-51, It will only fly at 175 mph with the rudder deflected (at full power!). Tell me there's no drag there?
On the approach, 130 ias, idle power, full flaps, rate of descent was about 2700 fpm. That's falling like a brick as it is, considering a 'normal' approach with 25" Hg gives -500 fpm, and that's not enough for you? You need to drop faster, slow down faster? Then I deflected the rudder and maintained 130 ias, rate of descent was off the gauge, more than 4000 fpm!!
I think the problem is in the landing technique, not any flaw in sideslip drag.
