I just got back into rocketry after 20+ years and recently dug out my old Estes Command Control launch controller. After putting in two fresh 7.2V NiCD battery packs I launched several F15 rockets and a couple of 3x D12 cluster rockets. So now I'm wondering what the motor limit is for this launcher? Does it only work with Estes igniters? What's the biggest thing I can get going with a 14.4V rapid-discharge NiCD launcher?
