Here's something I stumbled across that might help you.
You might also look into faster quick drying concrete.
I've done small casting in concrete but never in a rotocaster.
I would pay attention to:
Set time- Set is how long the concrete is going to take to set up so you're going to want to leave the rotocaster running for at least that amount time. And if you're looking for a high level of detail, you going to need to water it down even more, which adds to your set time.
Cure time- I wouldn't even take it out of the mold until it got closer to the end the cure time. That way you know it'll be safe to handle.
The speed of the rotocaster- As it drying, concrete will get thicker and likely to fold in on itself. But if it spinning fast enough, I don't think you'll have an issue.
Good Luck. :)
