Hi, all.
When doing DD with two altimeters, which I have never done, I have a question.
Say your rocket needs 1.3g of BP at each end to deploy main and drogue respectively. If you are using two altimeters, how much BP do you put in each charge well? Or, do you just use one charge well with two e-matches in it?
If I'm not making sense, try this--if both altimeters detect apogee at the same time and both ignite their matches at the same time, and if you have each match in its own charge well, and if you have 1.3g of BP in each well, then you end up with a charge that is twice what you need, no?
But if you put half in each and only one detonates, then you risk not getting separation, correct?
So ... do you put one charge well at each end with two matches in each one?
Thanks.
