Hi Jos,
Yes, you do have to wait and no, I don't think you need an indicator light,
because the change to reverse is continuous and so quick, but it is
important not to be able to select reverse, or "unreverse" with the throttle
open, because when it goes through zero pitch, it will over-speed the
engine. A micro switch on the throttle box to break the circuit will do the
job.
Best wishes,
William
