I just looked through the changes - nice to see some clarifications in there. Also....Million Feet Award! It's time to start logging for that one.

Also noteworthy is that this rocket is set up with twin altimeters and redundant charges.

Congratulations! Can you tell us how you ignited the motors?

 

[n27sb]

I just used the regular igniters that come with the AT motors. All wired in parallel with a good hot 12v system.
I used about 3' of 18g twisted pair as the leader , connected to the clips. I scraped the clips well to clean them up. lightly taped the rocket end of the leader to the fin. This allows for a foot or so of liftoff before the wires pulled
off. Sorry no picture.
