Spit flaps are only used for landing and they are deployed just before touch down. They also cutt off airflow through the radiators, so as soon as your down you either retract your flaps or overheat your engine.

They look as if they deploy pretty fast, I've seen it a few times.
Aren't they deployed with pressurized air? In some ww2 fighters flaps were cranked down by the pilot (109?)
Not sure about that radiator thingie, but on the Mk I, the undercarriage was obstructing the oil cooler, so one would not have to much time for taxiing before boiling over.
Some early Mk I's also had a hand-cranked undercarriage BTW...

A flap run on hydraulics should open at the same speed regardless of airflow. Standard pressure is 3000 p.s.i. on todays planes, not sure about ww2 era.

Fixed in AH2! Pyro altered the Spit's flap deployment rate in Beta 29.

cool, is airflow's counter-force there too?

If they are moving to 98deg, wouldn't they take a while compared to aircraft that have multipositional flaps and you are using just one notch of flap? When I cycle through all three or four positions to full down, that really strikes me as taking forever at least using the sound as a cue. Shouldn't the concern be with how fast they move in degrees/second?

No... spit flaps have 2 settings, either up or down.

All I know is they had a totally new soret of flap the 'split-flap' and I can't be bothered to explain them but I'm sure someone with a much better understanding of aeroplanes will explain. This is why some early spit pilots called it the 'splitfire' (clever eh?)

Read Puke's post again.

He's mentioning the total time required to deploy normal multi-positional flaps fully, compared to the Spitfire's 2 stage flaps.

Unless the Spitfire has some sort of a hydraulics system that works much quicker than other planes of that era, it should take as long, or longer, than full-flap deployment of other planes.

If the Spitty flap should be sped up till full deployment, then the flaps of other planes should also be sped up.

Just a note: Flap drop and raise much quicker in AH2
