K'Tesh's OpenRocket files...

[K'Tesh]

I have one of these assembled but unpainted. Any details needed?

Thanks for the offer.

Nope... Before I left the US, I had scanned the fins and the decals (with rulers). So, this one is good.

Woo! I have some oddballs coming my way at Airfest, I'll try and remember to give them the works. Poke me if I don't :-)

[K'Tesh]

Finally got around to simming the decals on the K-47 (short) version of the Estes Cherokee D.



You can check it out in post #23.

[K'Tesh]

Still need the plans for the Arapahoe E... I've figured out a better way of doing the fins in OR, and I'd like to get this posted.

[EDIT] Due to a dispute with the current owner of the design, this will not be coming to a thread near you. Sorry folks... you can take it up with Don.[/edit]

I'm in Mobile, AL, on the coast. Those are all way too far away from me. Thanks for the thought though.

oops... thought georgia

I've been wanting to do this for some time now... And now it's done... The Cineroc/Omega files have been all reworked:



You can view the updated files in post #1
__________________________________________________ __________________________________________________ _________

Please note! All previous versions of the Cineroc/Omega .ork files are obsolete! My old techniques for fin decals, and launch lugs induced changes in flight performance. These new files are much more accurate in appearance, and should give pretty accurate flight simulations... Especially the Cineroc versions, as I was able to resolve the problem that was resulting in N/A altitudes.

On some of the sims (marked as having rail guides) I simulated the guides. The actual guides were made from card stock, and were included on the body tube marking guide. To replicate them, I had to make the guides twice the thickness of the card stock, plus the thickness of the standoff (3/32").

Versions marked as "(Mod)" have been designed to take D/E motors (instead of D only), as well as having added TTW fin tabs, and enlarged launch lugs to accommodate a 3/16" launch rod, instead of the stock 1/8" launch rod.

Eliminating the engine hooks' phantom body tubes will eliminate the warnings about Discontinuity, and Jagged-edge fins, and flight characteristics may also improve (it's up to the end user to remember to add the weight of the engine hooks in that case).

Redshifted rockets will be marked with "(Mod)" to identify them.

The Big Daddy file is up...



I cracked the problem I was having with the fins decals... I had to add length to account for the fin tabs.

[kcobbva]

As promised...



(At least THIS Big Daddy won't lawndart)

Fin measurements and decals were taken from scans provided by Kruegon.

My fins (using Kruegon's scan) was 1/16" different from his .rkt file. I printed the fins with the ruler, then cut the ruler out and used it to make my measurements.

Man you are good!!! This is a great looking Big Daddy! One of our favs

[K'Tesh]

Thanks kcobbva! I'm glad you like it. I didn't mod the file for the changes to the nosecone that I'd do... That's outside of OR's abilities.

I did a little bit of work on another file today... I hope you all like it.



Mind you, I didn't add the decals (would have required an air fin)(and that's just a bit more trouble than this file is worth), and I rotated the black fin to move it away from the launch lug (easier masking).

Motor is shown overhanging the body tube by 1/4". In reality, it looks like it could have completely slid inside the body tube.

[K'Tesh]

Oh... and I updated my OR tutorial for fins to now include how to attach surface mounted fins to a curved boat tail. I discovered this trick just recently.

[Charles_McG]

Thanks the tutorial thread. I was having trouble importing a fin (as a .PNG). I still don't know what the original problem was, but I mimicked your instructions in the tutorial, and it worked.

Sounds like your fin was hexed or something...

Speaking of hexes... I worked on this for a spell today...

Estes Zoom Broom (853)


'bout time I finally tackled a Goonybird.

A PBT was used for the engine hook, and I attached the air fins to another (you can delete them if you want to get the flight performance the image indicates).

Fins and decals were derived from those found over on plans.rocketshoppe.com.

[K'Tesh]

Rex, you'll be pleased to know that I've updated the .ork file for the A-20 Demon clone.



The file can be downloaded in post #73

[K'Tesh]

I'll stick up for this one... The Estes Defender (1924) has been updated now...



You can download the updated file in post #60.

As a USAF Veteran, I just might need to build that one someday.

I built it before I was even an enlisted Airman.

[K'Tesh]

Continuing my love for two stage payload rockets... Here's Estes' Supernova Payloader (2011).



WYSIWYG (except I edited out the CG/CP markings). I also altered the "paint" on the booster's fins to make them visible (black on black and they disappear into an odd looking mess). Went with gray for the silver. With the "silver paint" the finish looked really grainy, and due to the difference in the lengths of the parts it was "applied" to, it really looked bad. Also the file size balloons tremendously with the "silver paint" graphic.

Just in case you didn't know, this one is actually back in production again.

I've built four. One was finished before it was destroyed (crushed body tube (not from a launch)), two unfinished clones, and a BT-60 upscale.
Let's hope the Omega can make a return soon.

Hey KT,

Do you have a Sea-Strike D in your arsenal? Think we need to represent the Navy too!

Sorry fm,

The Sea-Strike D isn't in my arsenal. However I was working on a clone of the Phoenix Missile. Then there's the STANDARD missile. Maybe I can push those for you. Oh, and Hojo fans, if someone will get me a scan of the fins and decals of the BT-55 version, I might be able to get the Army represented.

Tanks? No, Bombers! I was USAF. Our goal at the time was to nuke'em till they glow, and let you guys shoot 'em in the dark. Glad it didn't turn out that way.

Thanks to all our Veterans, Active Duty, and Emergency Personnel out there.

[Forever_Metal]

They will never see me coming...

I was a BUFF Crew Chief before I transitioned into the B-2 program in '93. I'm a SAC trained killing machine! Lol!

[Forever_Metal]

My dad was a 52 jockey 68-71

[K'Tesh]

Me, I loaded F-111E Aardvarks and EF-111A SparkVarks. Bombs (anywhere from 5lb practice munitions to nukes), AIM-9 missiles, chaff and flare (no bullets tho (no internal gun)), occasionally I'd hang fuel tanks, or assist with the ECM pods. Mostly spent my time loading, unloading, or maintaining them.

I just stumbled across your OpenRocket thread. You do some amazing cosmetic reproductions here.
From a simulations standpoint, how did you achieve the ring fin on the solar flare? Was it just a tube expanded to the proper diameter? And does it function for flight simulation purposes or does it give some sort of diameter discontinuity error?
