Can I use Radio trigger + flash with old cameras?

...Electrons travel at/near the speed of light so the slowest part of the chain is the shutter...

Don't forget processing time. There are a lot of things happening from signal reception to actual flash trigger.

True. I use the Flex TT5's and regularly shoot at speeds over 1/1000th without issue.

What leaf shutter operates at 1/1000th?

Or is this a FP shutter with a flash that fires multiple times during the exposure?

The Super Speed Graphic had a 1/1000th leaf shutter, but I think they were prone to failures.
