Second flight was an Estes X-Prize Thunderstar

Staging went well, but 3 of the 6 shroud lines were stripped off the parachute at ejection since the rocket was moving quite fast.

isn't that rocket a 2 engine cluster? did you chad stage both??

It was an X-Prize Eagle, and I've fixed my original post.Originally posted by Loopy
Yeah - what he said!!!
Well, no amount of delay in the world would have kept the parachute shroud lines from being stripped off in this case, but your point about longer delays is well taken.Originally posted by powderburner
This points out one of the other considerations for selecting upper stage motors; you need a slightly longer delay charge. Estes highlights (or at least, they used to) some of their motors by marking them with purple ink and using delay intervals that are a couple seconds longer than the 'single-stage' counterparts.
Yes, you better do something to check stability with CHAD boosters. Especially with the drought in this part of the country and the grass fire hazards, we don't need a horizontal cruise segment and a ground ejection.

thanks for clarification!
however, now that you got me thinking...hmmmm, double-CHAD staging on the Thunderstar??! maybe have to try that
BTW - the Estes X-Prize Eagle flies great as a 2 stage using Gap staging!!
NOT the most pleasant of sights!Originally posted by andysrockets
with cyder in the frame too.
DO you think my richter recker will work chad staged with 3 d12's to 3 d12'sOriginally posted by jflis
So long as you don't tape the CHAD motors to *each other*, CHAD-staging clusters works well. Biggest problem is that you are adding a LOT of extra mass, so stability becomes a concern. Also, you have more than one motor casing droping from the sky.
My experience is that the motors stage at such a low altitude that the motors tend to stay clustered around the launch pad so it isn't that big a concern.
My biggest CHAD was a 4 motor cluster (total of 8 D motors) in my Dudley Do-Right

by the way ive also done it with my 24mm upscale duces wild. 2 d12'0s chad starting 2 e9's... it's lots of fun when so much can go wrong..
jim F. you should make a kit like that...
