Hello. I am wanting to launch my Madcow Torrent with chute release and discard the dual deploy for this flight. I am using the av bay as an open coupler and so have one long section of 48.5” from the top centering ring to nose cone. An ejection calculator calls for 4.21 grams of black powder. My charge well on my 38mm forward closure doesn’t even hold that much powder. Is that a sign that my rocket is too long for single ejection? I did extend it a couple feet from the stock kit.
