Here is my version of the Star Wars Discord Missile. I decided to delete the froward nose
fins as they make the design unstable. For as many add on tubes as this design has the
preformance seems to be good. Gotta love this sci-fi stuff .

Enjoy and Thanks Again, JP

Craig and James,

I took your suggestions to heart (for the most part), and here is "Laser Wolf" Version 2. I hacked 5 inches off the BT-60, and moved the small fins forward from the LT-115. I put the fins on a diet, and reduced the largest fins from a 1.68X upscale to only 1.36X (about 26% smaller now). I moved the launch lug aft, and put it on a standoff.

While I was able to switch to a C11-5 instead of a C11-3, the launch rod lengths will need to stay at 48" for the C11 and D12 (which appear to stabilize at 38" and 35", respectively). The E9-6 doesn't "get stable" until 44", so a 60" rod will still be needed.

I really like this design Jay. This one get my vote for your next kit release . I you don't like the fin standoff amd the launch lug placement concider the following.


Cut that LL330 in half or just use two LL320 launch lugs.
One LL on the upper body tube and the other on the side of an large fin.
You end up with an Upper LL and an Lower LL. (Lower LL in rocksim Make Inside Tube)
One drawback to this is a launch rod is needed for alignment during assembly .

Once again Jay, Great Design!

Your Pal, JP

Jay,

I like what you've done here, too. Dv numbers are high, but not horribly so. She just needs a bit more "kick" off the pad (like a lot of us...).

I'm still trying to figure out how I could inspire anything to go on a diet...

Craig,

My wife's been insisting for years that I could lose some weight. I keep telling her I'd look stupid without a head and one arm.

I didn't start gaining weight until after I'd met her. So I ask her if she'd like me to be fat and happy or thin and miserable.

She tells me that's *not* what she means. I just say, "Oh, well."


Cheers,

*I'd* probably pick something a lot simpler.

Although I'd need to figure out a more effective (not to mention aesthetically pleasing) method for compiling instruction sheets.

Y'know, Dave at Sirius Rocketry uses black and white photos. (--Hmm...)


--Sorry, did I say that out loud?


(It doesn't help that I get distracted with writing songs and screenplays, either. )


Cheers,

You want distraction from rocketry? Try PHP/HTML/CSS/MySQL haiku...

Call it 'Ode to a BLOB I once thought I knew'...

My hair drops in clumps and my face turns dark blue...

Cause it takes all my time from drawing something new...

I Have been fighting with this design for some time now. I think I have finally got it in a version that will actually fly. DV's are good and most importantly the lift off velocities are acceptable with a 36" rod. The DV's are still a little high so I used 1/4" shock cord that is 36" long. Also funny twist is that I actually have built this design (All Semrco Parts) as of 02-08-08 and am just now posting the Rocksim file. OOPS! I will post photo's later of all that I have built before they under go the spring test flights hopefully with Jon .

A big THANK YOU to Carl nd Sheryl of SEMROC for sending me all the right part no matter how poorly I describe what I need. Carl always seem to go above and beyond the call of duty. Thanks Carl, the CR-KV-60 was exactly what I needed for the Tranquility 9 design (to be built and unvaled soon) .

Enjoy and Thanks Again, JP

WOW, James, just WOW!

Later,
EV

Thanks EV, I knew you would be tempted with the Sci-Fi design . I am glad you like it and lets hope it flies as well as it looks . One never knows when a test flight design will turns into a W.S.M. ( Worm Seeking Missile). Its happend to me twice now. LOL.
