Old UPS

You'll have to pull the batteries to use for the launcher. I just disassembled two APC 2200RM units and scored 4(out of 16) 12v 7.2ah batteries. Just for grins I tested a AT Firstfire igniter with one of my batteries and got INSTANT ignition.

How about using an old UPS delivery truck to launch rockets...

If UPS will deliver, I will launch.

What can Brown do for you?.... :)

Well you could mail a rocket by UPS express which will go into those brown UPS planes and it will get launched to about 33,000 feet to the other side of the world... I dont know of any motor (available to general hobbyist that is) that can take it that far...
