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.

[n27sb]

There was not one.
They accepted my submission but have not posted it yet.
Notice that it almost beat the H record.

Very nice! So is that the next record you're going for?

If you read this thread

Trident , an Airstart Cluster

I always wanted to do an Airstart Cluster. Ready to mount fins.

I was ready to launch Trident this weekend but weather was not good.
It was a G cluster that would exceed 3K.

I can load it with a total of H but it might exceed our waiver.
I will see how it does on the G first.

Congratulations again on the record.
I cannot find the page you have copied..I’m on the records committee, you would think I could locate it.
Could you post a link to the page.
