A bit more seriously, 8 weak D cells could still fire nichrome and Astron (?) igniters, but 4 weak D cells wouldn't do squat. So not long after the 4-8 upgrade, we bought the hookup kit to use the car battery instead. I can still vividly recall my dad pulling his 88 Olds down the driveway in our backyard so we could set up the pad just in front of it. RIP, Dad ! BTW, I'm still using that car hookup kit, but using it with a 12V gel cell. Doug .

My main launch duties are still handled by two 40 year old Astron Launch controllers.
I use the same battery in my flight-box for my R/C planes that powers my RC power-panel, R/C fuel pump, and R/C Sullivan Hi-Tork starter.

I never had an Electro-Launch (we used Estes' wooden Tilt-A-Pad when I was growing up), but you're right that it could be converted to 12 volt operation by adding four additional D batteries (I hadn't read all of the hard-to-read [on my screen] text here: http://www.ninfinger.org/rockets/no...a/69est086.html ). Here's the additional battery pack (an extra Electro-Launch base, sans launch rod and blast deflector: http://www.ninfinger.org/rockets/no...a/69est090.html ). I imagine it might have been used--along with an Electro-Launch pad--by schools and clubs who liked to fly a lot of clustered models, or (by itself, with a Tilt-A-Pad) by people who didn't need or want to drive to a flying site; it provided a portable if rather heavy "mobile launch" option.
