I'm having a little trouble using a Tele Mega for a 2 stage rocket. Using the altimeter configuration I set main chute opening for 750'. I set Pyro D as a backup main at 499'. Pyro A was apogee backup and Pyro C was sustainer ignition. So Pyro D fired on the way up rather than down and ended the flight rather quickly. I have solved that issue but the flight graph revealed other issues which I don't understand. #1 Why didn't Pyro A fire? #2 Pyro C seems to indicate that it fired (slight voltage dip) but it fact it did not. Why? #3 Pyro D voltage shows a steep decline. Why? Any insights would be appreciated.
