I've completed the "Scrambler" cluster rocket from SemRoc and will prepare to launch it and an egg, action figure, plastic egg, hard-boiled egg or similar payload once or twice Saturday at our final club launch.
As I am assembling my rockets and motors and mentally counting how many I need of each value, it occurs to me that I've overlooked something simple and basic when planning the use of THREE motors on each launch.
I understand that the three should be of the same value.... THREE A8-3, or THREE B6-6 or THREE C6-5
or whatever the recommended motors are. But as I look over my packages, I find I have a set of B6-0 boosters that i was planning on using up slowly on a two stage rocket later.
Why could I not use them in the Cluster rocket? That is, why not TWO B6-0 and ONE B6-6 in each firing. Or TWO A8-0 and ONE A8-3 or TWO C6-0 and ONE C6-5
After all, how many ejection charges are really needed to blow the top off a nosecone? Aren't the use of THREE such motors a bit of over-kill? Or does it really matter?
Is it more important to use all three motors from the same package so that they are identical in every way, or should I save resources and only use one such motor with an ejection delay, while the other two could be straight boosters?
Thanks for a speedy response. I will only have a limited amount of time for final packing late tonight, and tomorrow's launches will be a frigid affair (lucky if it's above freezing at any time) and probably running quickly to get them done and out of the cold in SE Ohio.
