Engine failure in the climb question

Ok all you bright sparks out there...my instinct may be wrong (and I hope it is) but I reckon you might well be on the way to meeting your maker if this should happen in an R22. Is there someone out there who can tell me how to work this out? I'm afraid my grasp of physics isn't quite up to the task...

60KIAS
500fpm ROC
Engine quits suddenly

1. How long will it take before you stop going up?
2. How long will it take before you establish a ROD airflow of sufficient magnitude to keep those low inertia blades spinning?

Low RRPM horn comes on at 97% and my guess is that most of us wouldn't have the collective on the floor until it got to this figure. That leaves 1.2 secs to establish an auto before RRPM becomes irrecoverable. Is it possible? If it is (at 500fpm ROC), at what ROC is it not? There has to be a ROC that shouldn't be exceeded. What is it?

Thanks for any answers.
