Two Stage Conduit

[roytyson]

How far up does everyone run the conduit past the motor mount? I am ready to epoxy in my motor mounts with conduit, I just have to cut them down to the final length. Just curious how far everyone runs them up the airframe.

I did not use conduit. I made a tunnel on the mmt. So if that counts, not past the mmt at all.

Not at all. You don't want it to get bent. As David wrote, a tunnel works fine as well, a couple of strips of balsa between the MMT and the airframe are an easy way to form a tunnel.

I cut it off right at top of MMT.

Is this for routing the ejection to the second stage motor?

Electronic staging for composite motors. If you have your ignition controller in your sustainer, you need a method of running the wire down to the igniter in the nozzle.

Thanks, makes perfect sense.
