Thanks Casey, I wasn't sure about the Q2g2. Hopefully they get here in time :-)

Your solution is exactly what I ended up doing: Extend it through the bulkhead, then put a straw around it. That has worked fine for me. Either way, don't bend it too much. I have used Q2G2 igniters for charges and they worked great. Just be careful with them because they're very thin, solid-core wire, so they don't take well to lots of flexing.

I am down to two ematches and ordered some Q2G2 in hopes of using them for a few flights this Sunday. Hopefully I can get them by Saturday afternoon for a bench test. Second, is the antenna.? There are a few ways I can think of doing this. Some may be better than others, but all have problems as I would see it. My avionics bay is only 7in. 1. is it best to mount the altimeter the furthest aft I can, and bend the antenna at the top. Would protruding the forward bulkhead and allowing the antenna the extra 2" enhance the link.? My thoughts here, are that just bending the antenna, would be best, so that it isn't damaged. I usually pack dog barf, a quick link, and a hefty 2 gram FFFFG charge. *54mm* I don't think protruding into the payload bay would assist in any way as the packing of the materials would bend the antenna. 2. Mount the altimeter as far forward as possible. This would allow the full length of the antenna to be above the bulkhead. I think this would provide the best wiring setup, but again has the draw backs of having the antenna in an active area, not safely in the av bay. In the future, I can just make a longer e-bay. But this is a retrofit, to lighten up my sons rocket, and use the stock coupler tube. I welcome any comments. Writing this, I think one of those clear poly antenna tubes from the RC toys may be the ticket. I can even put a dap of epoxy on the end to seal it off. Do the farthest back thing, and a short protrusion with the antenna tube.
