FWIW, I've built and flown several BP powered stagers with clusters in the 1st stage for getting it off the rod with good speed, and had good luck with all flights. I always take my time and make sure the nozzles are clean, the ignitors are seated fully in the nozzles and not shorted, and that all the ignitors are securely connected.
No doubt, you want a lot more than 4 AA's
