Wow. A rainbow vomiting unicorn. We don't have those in America. :tongue:

 

[qquake2k]

Left overs from Mork suspenders? I Like em but don't fit the metal theme. LOL

I can't believe I used to watch that show. LOL

 

[VonMises]

Really like the color choices, and the overall proportions.

 

[gdjsky01]

I see no issues with the color of the nylon. Just sayin'

The color of the nylon?

 

[o1d_dude]

The color of the nylon?

Yes, the rainbow colored nylon shock cord is politically correct.

Oh yeah, the nylon webbing. Duh!

Just think of it as flying the flag of the city of Cusco, Peru.

Why thank you, Jeff. It'll certainly show up on the ground.

 

[Spooks]

That is another beauty Jim!!

Thanks again for sharing, I use some of you techniques in my builds now, never forget about the hairdryer on those vinyl though, in case ya need it, Mark was right about it!!

Just realized that I quoted. DOH!

 

[qquake2k]

It's been a while since I've worked on rockets, but I'm hoping against hope that we'll have a launch next weekend. So just in case, I got some work done on the finishing touches. I'm using a 60" military parachute that I got from Aerocon. It had a tiny loop taped onto the end with some sort of space age tape. The loop wasn't big enough for the quick link, so I lashed it with some Kevlar and cut the tape. I also got the retention clips made, from 1/8" x 3/4" aluminum bar. Hopefully Death Punch will fly soon!

 

[o1d_dude]

I like the color scheme. And the rainbow shock cord. LOL!

 

[kpklein]

Five finger death punch???? Why not call it Love and Understanding?

Looking forward to seeing this on Saturday!

Ari.

 

[qquake2k]

Lord willing and the creek don't rise!

 

[gdjsky01]

I expect a HUGE long launch report!!!! Many many flights...

Waiting..... :wink::gavel::flyingpig:

 

[iter]

I'm with Jeff here.

We were in so much hurry yesterday, I was even less social than usual. I didn't even see you Jim. How did it go?

Ari.

I'm afraid you're going to be disappointed...

Hey Ari, I saw you and Leah from afar, but we were never in the same place at the same time.

 

[qquake2k]

I finally flew Death Punch! Photos and videos can be seen in my launch report.

Punched rite thru the sky... :clap:

 

[o1d_dude]

I think this is my favorite of all the rockets Jim has built.

What's not to like? It's big, it's colorful, it has a chute for the airframe and a second chute for the nosecone.

But next time I want to see it go up on an "energetic" J motor.

 

[qquake2k]

I have to agree, I really like it too. I got a lot of comments on it at the launch. I'm thinking about a J250 Fast Jack for its second launch. Should take it to about 2400 feet.

 

[qquake2k]

I was just reading the instructions for the J250FJ reload. It says it comes in a long delay only. I'm guessing that's 14 seconds? It also says it doesn't come with an ejection charge, I'll have to supply my own BP. I emailed Aerotech asking about the length of the delay, and how much BP comes with the I229T reload.

 

[gdjsky01]

I can not say this is my favorite since several have not flown yet.
:wink:

IIRC most new AT loads come only with long delays. You are expected to drill them as needed. I like this of course. As for no BP, that is news to me. I am frugal with it. I use 1 to 2 grams that come with a load as needed and always save any left over.

 

[o1d_dude]

No special sauce comes with the reload? Okay.

Long delay only? Okay.

Now about that motor choice. The J250 burns a bit over 3 seconds and produces only 8.2G of acceleration on MY 80 oz 4" tube fin. As a firm believer in the "Motion is Lotion" school of thought I consider 8.2g's a bit slow. I'm not sure how much the 5FDP weighs but got believe it's more than 80 oz.

Didn't you put it up on the I599 for the maiden? That one sims 27g's on MY bird so it's most likely a lot less on the 5FDP.

Try running a sim on the J540R and see if you like that. It's a 2.25 or less burn and a Redline so it peaks at about 650 newtons.

J800t?

I know, I need to get caught up. Next launch, I'll only fly virgin birds. I agree with the long delay. When I was flying a lot of mid power, I always ordered the reloads with the longest delay possible. You can drill down, but not up!
