Bulk packs are the way to go!
We used the engines with a bulk pack, and the group loved them. The rockets gained a significant altitude, and it worked great. Everyone was happy and impressed.
Have been flying with Estes for 57 years - back to the "blue tube" and nichrome cut-apart igniter days and when the Weekly Reader told breathless stories about Gemini and Apollo.
Appreciate the bulk pack's less packaging, easier to open, and better igniters.
