How does a stock Big Bertha on an Estes B6-4 compare for soft deployment values? Its the closest model I've seen that consistently has a gentle just after apogee *pop* for a perfect deployment speed. That is if its going straight up on a windless day.

It's even better with the C6-5... B6-4.....260'.....21 FPS.....427 FPS/S.....36" C6-5.....650'.....14 FPS.....470 FPS/S.....33" Those lengths at the end of the lines represent the distance up the rod where the model reaches safe flight speed.

You guys seem to have an inexhaustable supply of rocket design ideas oozing out of your melons!!!!
How about some designs that are constrained a bit for us lazy people who hate to cut tubes to a custom size, cut fins to any size, and print out custom decals. Basically a kitbash design using the pre-cut fins, tubes & decals from whatever kits that are currently available. Mix & match several kits if needed. The Renegade, the Screamin-Mimi, the Enduring-Freedom kits, the X-Prize kits, and heck, even the small kiddies kits like the yankee! (I love that cone). Thats one heck of a pile of parts to kitbash from. Just trying to come up with something to use up all these kits that I got at half-off sales. The older I get, the less creative I become. You guys don't seem to have that problem. Must be the power of cheese!

Chris,
I like the "challenge" of this idea, using standard parts to kit-bash across kits. I'm in!  Just a thought.....why don't we start this as a new thread? Later, EV

Done.
Look under some goofy titled thread about kitbash.

New Design: Moonbean Express
This may or may not be a new design. I tried to stay with a classic look so I hope you folks like it. I am still unsure of the placement of the launch Lug which is forward of the CG. I wanted to avoid a standoff fin which would have messed up the clean lines of this design. What do you think Craig, LL ok or not??
Thanks and Enjoy, JP James Pierson NAR #77907

Has a sort of early Bob Clampett / Chuck Jones look to it...  One thing you might try is using a longer lug, full-length of the payload section. This might reduce the chances for rod-grabbing and binding. Trim the top of the lug to match the angle of the cone... Another possibility -- create a "fat fin base" for one (or all three) of the fins and mount a second lug inside that base, then attach the fin on top of that. Shape and fill the joints to smooth the edges out. That way the lug blends in with the fin and is less noticeable. It also doesn't break the overall flow of the rocket's shape. Third possibility, similar to the last one, is to use two launch lugs on either side of one (or all three) of the fins, and fill in around them with balsa or just some filler compound, to blend them in. Make the lugs appear to have been part of the fin as decoration instead of as launch lugs... I agree, having a launch lug on a standoff would look bad. Even attaching the lug to the side of a fin, the way Estes did on some early designs, would distract the eyes.

We've been told that from time to time, Chris. Not always in those words, mind you...   More often it's phrases like "You're full of it!"... Somehow, the older we get, the words "cheese" and "oozing out" no longer seem to go together...  Quite the reverse, actually...

New Design: "Mars Voyager"
I was watching a Mars special on PBS about a month ago, and one of the computer animations featured a ship very much like the front end of the design below. Since it wasn't stable by itself, I whipped up the lower section, which oddly resembles the Centuri "SPACE: 1999) sustainer.
I'll have to revise this post later to add a parts list. All components are Semroc, beginning with the BC-2032 (Centuri PNC-231 "Orion") cone. RockSim says this model should fly nicely on a C6-3. Enjoy, --Jay "Shrox, I'm *not.*  --But apparently I look like I could be Shawn Switenky's big brother."

New Design: Silver Sleek
Here is a design I came up with called the Silver Sleek. My biggest problem these days is not new design ideas (Thanks to you Folks) but names for them. If you folks would please use your mighty Cheese curds brain power for some new names I will be very greatful.
Happy Easter to All and thanks again, JP James Pierson NAR# 77907
