HI,
I am doing a cluster of a J350 and two H128's. The rocket is too heavy to be lifted by just the J350 or the two H128's, so I want to get all the motors lit on the ground.
A few other people on rec.models.rockets had given me some very helpful information on ignigting clusters, and wanted to modify one of them.
I wanted to know if it is possible, and safe if I used two davey fire matches in the J350 that are each double folded, and with the match heads touching,I dip them in pyrogen? The two smaller motors would then just have a single dip of pyrogen. I thought that this would ignight the motors very quickly since the H's do not take long to come up to pressure.
Thanks a lot,
Tom Sak
