Ah, now this is a fun question. Here's how I would look at it:I'm looking for lightweight E-bay alternatives for dual deploy on a 2.6 dia. rocket. I am thinking of building a rocket to launch on the new AT I49, or I59 and need to keep the weight down. I'd prefer to build something a little bigger than minimum dia. and think a 2.6 inch rocket is doable while still staying around 2 lbs loaded weight. See Impending doom thread about an I49build/ launch. http://www.rocketryforum.com/showthread.php?t=4146
Aside from the motors which weigh a lb. or so the biggest mass contributor will be the e-bay. The LOC E-bays are built like a tank but weigh a ton. I have a LOC standard length e-bay for a 3.0 BT rocket and the thing must weigh 10 ounces, maybe closer to a pound ( I need to weigh it). I'm thinking I could lose the stiffy coupler and use aluminum threads and nuts on a 2.6 LOC type e-bay and it will still probably be too heavy. Any thoughts?
