I would be willing to wager that less than ONE PERCENT of launches are performed by someone walking to their launch site unless on ones OWN PROPERTY. Thusly, it is an insignificant MOOT ISSUE discussing use of a car battery and it's weight. Nobody caters to the fringe 1% of their clientele unless it is for extreme luxury goods with giant profit margins per sale (Such as Ferrari automobiles or Patek Philippe watches).

I prefer to do it RIGHT (With a 5Ah+ Wet Cell with 12+V) or not at all.
Li-Po cells offer a lighter yet still high-current alternative. I wouldn't use 4AA cells for anything over a low current ELECTRIC MATCH.

Back in my day my brother and I walk to our lunch site which was a few blocks from our house.We had a marvelous invention that we used to carry are ignition battery which I believe was an 8 volt deep cycle battery that came out of a golf cart for something of that nature.That invention was called a wagon and it had wheels and a handle you can pull it behind you with all your lunch equipment and your rockets stored in it I wish they still made those oh wait they do my brother still uses 1 to go out to the field His car when we launch at the Park with the club.

So I'm not crazy for thinking I read it in the NAR mag. I'm not saying I'm not crazy...just not crazy for that.

That "Spider" ignition method is interesting.
Seems it must be easier to get good old-fashioned black-powder in my area than there.
My local gun shop stocks FF and FFF.
VERY hard to locate FFFF any longer though.
