Well I get to build another or do some extensive repairs. Had an E16-6 CATO today. The result is not pretty..... *sigh*

EDIT: Oops, initially asked for date code but this is the same CATO you mentioned in another post. Motor date you gave is 04 15 13.Well I get to build another or do some extensive repairs. Had an E16-6 CATO today. The result is not pretty..... *sigh*
Photos of aftermaths are always appreciated by me to get an idea of the failure hazard.Well I get to build another or do some extensive repairs. Had an E16-6 CATO today. The result is not pretty..... *sigh*
Oh, no! At least they're cheap at Hobby Lobby.

I have a spare on hand, and another is on its way from Estes. It is simple and elegant and flies nicely. I definitely want to replace it.
I may consider basswood fins as Kruegon mentions above because the TCR sod farm site is big enough to go higher than the 2000 feet the Star Orbiter goes on an F26-9 especially if one uses a Chute Release. But quick sims push it to sonic speeds on even a baby G. This F26FJ flight got to almost 350 mph.
I must say, this is one of my favorite threads on this board. Excellent build thread of an excellent rocket with lots of great info, pretty pictures, and video. Thanks and kudos!
Fabulous build. I think I have read it 3 times now.
What at are your thoughts about using a g25 moon burner in it?

My real world data using the F15-8 in a Star Orbiter carrying an AltimeterThree and a Chute Release has it ejecting about 1 second after apogee....which to me is just about perfect. This is typical for the three flights I have on it on F15-8s (and is why I'm waiting for my local H-L to get F15-8s back in).
I also have two flights to just over 2000 feet on Aerotech F26-9s. There the delay is almost perfect - just a fraction of a second past apogee for deployment. In one case it fell all of two feet after apogee before deployment.
Maybe it would slow down more without the added ounce and a half of payload (plus what I did to make the top few inches a payload compartment).
The instructions tell you have to make a tape thrust ring....I did find the lack of motor block interesting myself, but that opens up other possibilities as long as one stays reasonable (and away from transonic speeds )
Hi Bernard,
I'm going to build one of these as well to use both the Altimeter 3 and the Jolly logic Chute release... May I ask you how you rigged the altimeter and the chute release for your Star Orbiter?
Did you build a separate bay for the Altimeter?
Any ideas or suggestions will help!
Thanks!

Thanks Rich,
I was thinking just for schmidts & giggles of making a small nose cone bay (like Leo did) to house the JL3 to keep it from just jangling around with the chute release pack....I'm also thinking about a streamer about a third of the way down the kevlar cord to the main body to act as a drogue of sorts until the JLCR deploys the chute...Does that sound like it would work ok? I would be trying a more traditional dual deployment system like the OP, but I live in NJ, which is really a "nanny-state" when it comes to obtaining black powder to make a traditional deployment charge.... I would have to apply for a firearms purchasing permit to correctly/legally obtain the black powder, hence my interest in the JLCR!
Thanks for the information!
Cheers,

The Chute Release needs to be in with the 'chute, of course. The AltimeterThree can live there as well, but on all three Star Orbiters I've built I used a BT-60 coupler, a ply disk and a screw eye to create a payload compartment from the top six inches of the model. One or more altimeters can ride there easily.
I have been using the little protector "bag" that Dino Chutes (and JL) sell to protect the Chute Release a little bit (and make it more visible on the ground which helps when one forgets to tether it )
Ah, so you were the one flying the Star Orbiter at the WAC launch at Sixty Acres a week ago! Nice. The F15-8 is perfect for it.
I was too wrapped up with the TARC launches to get mine in the air....I did bring it.
I just got one at Hobby Lobby for 14 Bucks with the coupon...looks like a real hot rod!
Thanks for the info., are there any online resources that would help me learn how to build a payload compartment?
Thanks again!
