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.

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.

Yes. Chris has it. I bought it from him at NSL-2018, and he had it recently at NSL-2021. If you have not visited his trailer at a launch, it is pretty amazing. I typically buy motors from him if he is at a launch — especially the single slug F reloads for the 29/40-120 RMS, which require Hazmat if shipped.

The Russians call the Soyuz--which has another stage atop the R-7 ICBM-derived boosters/sustainer assembly--a three-stage rocket, but it is actually a boosted two-stage launch vehicle, like the old "balloon-tankage Atlas" (with separating booster engines) Atlas-Agena, Atlas-Centaur, Atlas-Burner II, etc. By itself, with no upper stages, the original Atlas--like the Soviet R-7 ICBM, which also had no upper stages--was a "1-1/2 stage" (boosted single-stage) ICBM.

Speaking of clusters, here is my 3x29mm UltraViolet III, lifting off the rail at NSL in Alamosa, Colorado. Powered by three F15-6 engines. Ignition from Quest Q2G2 igniters.
