If a plane has enough power to maintain speed the need for any offsets is lost.
Not to poo poo the old fighters -they were the king of their day - current unlimited aerobatic stuff tho is far more powerful -power to weight
Example -- a Pitts 12 will pull away almost vertically from a vertical stopped position.
On models of bipes we designed for TOC- one problem was thrust setup - some needed up thrust - why?
simple - not enough power -- they were always slowing on verticals and requireg a bit of upTRIM -even tho it was not readily apparant.
add more power - the need goes away . We did this year later using more powerful engines - not available in 1990
