Just a quick further update on this - current files for ME (so not released yet), which will be in the upcoming update:
I'm testing out of Bidford as I know the field there rather well, the strip is roughly two and a half thousand ft, using standard ISA I'm taking a touch over a third the runway length to take off. It's not perfect, but given the upcoming prop adjustments it may get closer.
Climb rate, 600fpm is the aiming point for the setting and it is the rate at which speed is stable. I can hit 900fpm if I pull the nose up, but the speed is decreasing, so as far as I am concerned it is on the mark.
