Success! I test-flew my Sirius Interrogator tonight, although the A8-3 first flight was a little nerve-wracking. The two B6-4 flights were much more satisfying. I saved some B and C motors so my wife and girls could see it fly next week. :cool:

I forgot to wrap masking tape around the motor on the Tau Zero's maiden flight, so the body tube core-sampled about 3/4" of slightly moist sand (in the alfalfa field) after spitting the motor. The Prometheus, on the other hand, spanked the sky rather soundly on just an A8-3. :D (Craig, I think you'll like its performance!)

The best part is I got to fly on the site where my mom and dad's old farm was before they sold it 17 years ago... and where I flew the majority of my rockets growing up. :D :cool:

Gotta go finish writing some "Interrogator" reviews! :eek:

Hope the Tau Zero wasn't too badly damaged...

I'm looking at the parts for the Prometheus (they arrived this morning) and it actually seems bigger than the RockSim images make it appear. That A8-3 should have reached about 250'. I'm really looking forward to flying mine now. :D

I'm looking at the parts for the Prometheus (they arrived this morning) and it actually seems bigger than the RockSim images make it appear.My RockSim file says it's 18.65" long, in contrast to the Tau Zero, which is only 15" long.


That A8-3 should have reached about 250'. I'm really looking forward to flying mine now. :D That would be about right. I was *really* surprised at how it ripped off the pad into the sky. I didn't think it might possibly be a high-performance design, just that it looked cool and different from other rockets. :D ;)

Okay, Paul (and the rest of you), here you go. They're not terribly impressive, because I learned how difficult it is to prep the rocket, push the launch button, track the rocket, take pictures, and recover the rocket is for just one person. :rolleyes: (I need an "exhausted" emoticon here.)

Very clean "core sample" in that shot, Jay. The body tube doesn't look damaged at all.

My RockSim file says it's 18.65" long, in contrast to the Tau Zero, which is only 15" long.

What I meant to say was, the Prometheus "looks taller in person than it does on the screen"...

I now have the upper section all glued up and stacked into the lower section, and the fins have been cut, edge-sanded, and root-edge prepped. The proportions of the model just seem to "work"...

...I was *really* surprised at how it ripped off the pad into the sky. I didn't think it might possibly be a high-performance design, just that it looked cool and different from other rockets. :D ;)

It's a good design, Jay. And using RockSim simply made it easier to "get it right" before building it. Watch out when you use "B" and "C" motors, though. The Dv numbers are a bit high (B4-4 and B6-6 are right at 30 FPS, and the C6-7 is 24 FPS), so you might want to use reefed shroud lines...

What I meant to say was, the Prometheus "looks taller in person than it does on the screen"...Funny. Bill said the same thing about me when we met at NARCON. :p ;) :D


The proportions of the model just seem to "work"...And I've discovered that's the unconscious part of the designing process. It's when my brain finally said, "Okay, *that's* cool. --Quit tweaking it now and leave it alone!" :eek: :rolleyes: :cool:


It's a good design, Jay. And using RockSim simply made it easier to "get it right" before building it. Watch out when you use "B" and "C" motors, though. The Dv numbers are a bit high (B4-4 and B6-6 are right at 30 FPS, and the C6-7 is 24 FPS), so you might want to use reefed shroud lines...That's an excellent suggestion. My RockSim numbers are slightly different from yours, since I only have the motor sticking out 1/4", instead of the default 1/2":


Motor / Alt. / Dv

A8-3 -- 223 ft. -- 5.9 fps
B6-4 -- 559 ft. -- 29.41 fps*
B6-6 -- 568 ft. -- 33.15 fps*
C6-5 -- 1237 ft. -- 43.28 fps*
C6-7 -- 1261 ft. -- 21.73 fps


But yeah, I'll need to do the "reefing" bit, for sure. I guess I'd have to recommend these motors: A8-3, B4-4 or B6-4, and C6-7. And maybe switch to a streamer for that "C" ... if you want your rocket back, that is. :rolleyes:

That's all I ever allow on any design. Just enough to grab with fingers or a pair of pliers after the flight...

And maybe switch to a streamer for that "C" ... if you want your rocket back, that is.

You could also cut back to a 10" parachute; the descent rate only increases to 13.125 FPS, which isn't too bad. RockSim recommended a 2.375" x 23.75" streamer for this design when using the C6-7 (the size of the streamer changes with the motor used...).

Update on my Prometheus model: I now have the motor mount and fins installed, only requiring the launch lug to be added. It'll be primer-ready by this time tomorrow.

If by "Admiralty Colors" you mean silver, gray, black, and some shade of orange, maybe; it looks good in the RockSim 3D image. I may not match it 100%, but it should be close. And I still have that "Edda" font name decal image to apply...

Addendum: Model is now complete, construction-wise. It's sitting in the primer-queue, waiting its turn. There's only...30? 40? 50? ahead of it... :o

I'll try to move it ahead of some and get it finished sooner. I really want to see this one fly...

I might, Bill, I might...

Actually, over the past couple of weeks I built AND painted two rockets for my two Cub Scouts, for the pack's annual Rocket Shoot this past Saturday.

AND sanded the balsa fins, AND sealed them with CA in one case and wood glue in the other.

If I could find my camera, I'd even have proof!

In lieu of that, here's the thread from TRF with RockSim images:
http://www.rocketryforum.com/showthread.php?s=&threadid=27014

The fins on the Demon Rider are 1/4" smaller in width and length than shown in the picture, so the points on the inside trailing edge don't actually touch the body tube. I couldn't get the fin template to fit on the 4" wide balsa I was using, so I just made the fins a little smaller.

Both rockets flew great on both Saturday and Sunday, btw, with the exception of the Bat Wing's ejecting its motor on the first flight, barely popping the nose cone, and crumpling the first 1" or so of the body tube when it hit the ground. Using one of those old flimsy Quest motor hooks and having the nose cone a bit too tight just didn't make for a successful flight.

JRThro

And partially sanded it, too!

Btw, Scott has told me he won't let me beta test his next kit unless I actually finish the Odyssey, so... given time, I'll finish it.

Btw, I can think of 4 rockets, off hand, that I've actually painted. There could be 1 or 2 more, but I wouldn't put money on it.

I did finish the Tau Zero over the weekend, and I started on the USS Atlantis that arrived on Saturday. Two problems.
#1 Jay, how did you mount the launch lug? Does it have a standoff or is it mounted on one of the inner fins?
#2 The USS Atlantis kit has some of the worst looking decals that I've ever seen. They look like a cleanup of the original scan that was started and given up on. The colors are off and everything has a blue ghost that surrounds it, which leads me to believe that the paper moved during the print process. I'm going to e-mail Pimp Daddy to see if I got a bum set or if they're all like this. I'll try to scan them tomorrow and let y'all see for yourselves.

The "ghosting" around things could also be an artifact from the .jpg file that they probably printed the decals from. Since JPEG compression is lossy, if a file is saved with too much compression, there can be ghosting or blurring around what should be nice crisp lines, etc.

EDIT: I've attached a jpg file showing two copies of some simple shapes. The first copy was saved with not much compression and shows very little ghosting. The second copy was saved with too much compression and shows too much ghosting to be acceptable for a decal.

I was *really* surprised at how [the Prometheus] ripped off the pad into the sky. I didn't think it might possibly be a high-performance design, just that it looked cool and different from other rockets.For those of you who are thinking about building a Prometheus (i.e., Craig), I'd recommend that you use 3 feet of elastic shock cord, in addition to your Kevlar (TM) thread. That way, you should be able to avoid "whiplash" damage, as you can see from the closeups below. :rolleyes: (I only used 2 feet of elastic. :o )

You can see the silver smudge on the black fin, as well as the black smudge on the silver payload section. :eek:

I always thought that a good rule of thumb for shock cord length was about 3 times the length of the rocket. How would that work with the Prometheus?

I've been using three feet of Kevlar and three feet of elastic lately. That said, my Q Modeling Rogue uses no elastic at all, just a nice piece of heavy duty Kevlar, and I've yet to have a problem.

Thanks for the reminder. I was trying to use "stock" Semroc lengths (except for trimming the Kevlar so it doesn't "protrude,"), hence, the 24" long elastic cord. :o

The Prometheus is just over 18" long, so with a 36" shock cord (outside of the body tube), we'll see on Saturday if "twice as long" helps minimize the "whiplash" tendencies. :D :p


It's always good to have another rocketeer around to remind you about "the little stuff!" Thanks!

(This is a separate report from the full flight day activities.)

As part of my afternoon flight session, I managed to get the Prometheus up on an A8-3. As with the Tau Zero, this was an arrow-straight flight, with no noticeable rotation or extreme weather-cocking. The flight to apogee was smooth and the model seemed to reach a reasonable altitude. Parachute deployment was quiet and gentle, which is what RockSim predicted for this motor.

As with the TZ, I didn't feel like chasing the model by myself, so I limited the flight to the A8-3. It seemed to get higher than the TZ, probably due to the reduced overall drag. Prometheus is a traditional design, generally clean to the slipstream. It will be interesting to see what this model does on a different motor, either a "B" or the 13mm A3.

This is a great design, and flies so nicely that it will get flown again in future sessions.

Cool! And thanks!

(chuckling) Got pics? ;) :D


Cheers,

Not this time, and it wouldn't have been much to look at given my current status with cameras anyway. If I can get one of my local buddies to go with me next session, I'll get some. No promises as to flight shots, but I'll see what I can do. I wanted them, too...

It's sanded primer right now, but now that it's flown, I need to get serious about which color scheme I want to go with. White overall with green NC, maybe a green decal stripe just below the NC, and one black fin is one combination I'm thinking about.

I forgot to wrap masking tape around the motor on the Tau Zero's maiden flight, so the body tube core-sampled about 3/4" of slightly moist sand (in the alfalfa field) after spitting the motor. [SNIP]

The best part is I got to fly on the site where my mom and dad's old farm was before they sold it 17 years ago... and where I flew the majority of my rockets growing up. :D :cool:This morning in church I talked to the guy who owns my "old home place" (which is a giant hayfield this year), and he said, "I know what you're doing out there (i.e., flying rockets), so it's okay with me. Come out any time." :eek: :cool:

Too bad he hadn't said that two and a half weeks ago. I missed a couple of *beautiful* flying days this fall. :(

OTOH, I managed to finish the paint job and try out some preliminary decals on Tau Zero Prototype II. :D Looks like I need a clearcoat, a calm day, and I'm (*finally!*) good to go!
