How many batteries in a model rocket launch controller?
batteries August 21st, 2009I have 100ft of 16 gauge wire. How many AA batteries would it take to launch small C or D estes engines?
2 AA will start a standard igniter for a C or D engine. But the resistance imparted by the wire you are using is the real question. 4 AA would be better.

at that distance AA batteries will not work… not enough amps… you need 12v from a large battery
some sort of rechargeable or car or small tractor battery is needed
