That total lack of any perceptible delay (plus the confidence of being able to ignite clusters) is great! The old 12 volt Estes FS-5 Astron Launch Controller was that way, and I've been considering getting a Pratt Hobbies 12 volt system to regain those capabilities *without* the need for a car battery.
